The ModMic is also excellent, and you can attach it to existing headphones [1]. I use this at home with my prized Sennheisers.

It baffles me that some people don't seem to care about their audio quality on calls. The most obnoxious are those who use speakers and you get echo on all your talking, and despite telling them, they still never bother to get a decent mic.

Another common offender are the Bose QC35s: they have a terrible mic - I wish people would stop using them.

All the Apple things have great mics. I always keep an old pair of 3.5mm earpods in my bag as a good, portable laptop mic.

I see comments along these lines here all the time, and I don't get it. I'm on zoom a majority of my day, and have maybe two colleagues that don't just use the laptop mic/speakers and have a headset. I almost never have trouble hearing or understanding or listening to background garbage. In fact, those with headsets will sometimes be worse because they're making a lot of mouth sounds close to the mic.

Maybe it's just that Zoom is good at this? TBH, when we used to use Webex on dedicated phones I felt like I couldn't ever hear or understand anything. Maybe that's where this microphone feedback comes from?

If they're using external speakers, the only reason you're not hearing echo is because it's being software-cancelled. Different systems are better or worse at this software-cancelling; phones are good, Apple computers are good, otherwise YMMV.
I assume it also depends on if they are using the laptop speakers or some standalone ones. I'm guessing the cancelation tech is tuned for the onboard speakers
This depends. On my (dell) laptop, the mic is basically right between the two speakers, below the lip of the laptop. It’s possibly the worst placement you could come up with for a microphone, because it barely picks up voice, and picks up all the typing, desk noises and speaker echo in the world. But I suppose that’s not surprising from the company that thought that a webcam beneath the laptop display would be a good idea...
I really thought they had some clever software or leasing to make the picture appear as if you were looking into it because of the placement but nope...just a nose cam.
Yeah that would make sense
Teams is good, Slack is good, Zoom is good. Which ones are bad?
Google hangouts is the worst in my experience. Bringing external people in who aren’t used to google meets are always surprised. We buy everyone nice microphones and our meeting protocols are you unmute you talk then remute when done. We have a bunch of parents so this has been a good practice no matter what.
Those are all good until they’re not. I’ve had echo and other room audio problems crop up intermittently in all three of those platforms during calls.
Interesting. I normally use the external speakers on my iMac. I have verified with a number of different people that they're not getting echo.

Yet one sees other people utterly convinced that using external speakers is bad, bad, bad.

That may explain it.

The most common problem I see is not echo, but software audio ducking that happens as a result of using onboard speakers and mic.

Some people have a hard time realizing that they're interrupting someone else because that other person's audio is getting ducked while the laptop prioritizes mic input over speaker output - with the intent to reduce echo.

Almost. The laptop of the person being interrupted is essentially muting its mic temporarily to avoid sending an echo of the interrupter. You could say it's prioritizing its speaker over its mic.

Basically, of all the ostensibly unmuted mics, only the one with the loudest human is truly unmuted.

It's closer to half-duplex than full-duplex. Full-duplex with no artifacts requires no echo cancellation which requires headphones.

What does the term "duck" mean in this context? I'm not sure what you mean.
“Ducking” refers to lowering volume so that other audio can play on top of it. When an announcer speaks over a song in the radio, or when Siri lowers your music so she can talk over it - that kind of thing.
Try talking while they are also talking. You'll see the problem.

It's easy to have conversations with friends on discord where 3-4 people are talking at once all with headphones. However this has never worked on a zoom or hangout with less techy family members or work colleagues using ext. speakers.

That may be part of it. On calls that I'm on people generally don't talk over each other.
After having used both Webex and Zoom extensively for the past year, it seems that Zoom had much more aggressive echo cancellation up until recently. It feels like Webex has tweaked theirs recently so it's not quite as bad for those people who insist on just talking at their laptops with no external mic or headphones. Still, any of them with laptop speakers/mic sound worse than any other of them with a halfway passable headset.

I'd say if you're dealing with difficult people who really don't want to do more than point at an icon on a screen and go, the most bang for the (effort) buck is to ask if they have a set of headphones. Most people still have some earbuds around from when their phones still had headphone jacks. Just getting rid of the speakers makes a huge difference when folks refuse to mute while not speaking.

I was lucky enough to have an old Shure vocal mic and a cheapo XLR-USB interface sitting in a box of electronic stuff, so I typically put on my headphones and speak into the mic (on a desk stand). For camera...I tried the phone thing and while it does look a lot nicer, the phone gets warm and has to run for an hour or two at a time. Eventually just got a Logitech C920 once they dropped back to non-scalper prices.

A couple of clamp lights with parchment paper clipped over the end made more of a difference than buying a mirrorless camera would've (and they were way cheaper). My DSLR doesn't (and wasn't meant to) run for hours as a video cam so I didn't bother with that.

Also, using OBS and its virtual camera plugin means I can tweak and color correct the cam feed without having to dig into the OS webcam configuration. Plus, real chromakey beats crappy Zoom/Webex background removal when I do just want to goof around with cool backgrounds and overlays.

> don't care

Until you spend 1/2 hour talking to a certain family member, the one who calls from Burger King and sits right next to the soft drink machine so you can hear the ice being dispensed, you haven't fully lived.

I live next to a U.S. Marine Air Station. Until you get to share the full force of F/A-18s buzzing your place at full throttle, you haven't lived. Seriously - very loud.....
When Moffet Field was an operational Naval Air Station we would get P-3s, both going out to/returning from patrols, and circling around for touch an go landings for training, also C-5s and C-17s, and some fighters. The fighters were of course the noisiest, so you've got some serious loudness going on.
It's probably just related to crappy laptop hardware. Macbook speakers/mics are great and I never hear any feedback from them. When it happens, and you can hear your voice echoing on everything you say, it gets quite annoying.
> In fact, those with headsets will sometimes be worse because they're making a lot of mouth sounds close to the mic.

Yes this also freaks me out. Also when people use headsets in a room with lots of background noise, it sounds as if they use an open mic.

I'm also quite convinced that the Mac with just the internal mic/speaker is quite good for most cases. But I definitely want to look further into the issue. Also I certainly don't want to use a dedicated external mic, that seems total overkill to me.

Depends strongly on where your colleagues are. If they’re in a dedicated office at home the chances for background chatter are low.
I care, but not enough to ask people to QA my setup.

I don't know of a way to check how I sound without bothering anyone.

I mostly use Zoom and Webex, but both have an option (usually accessed via a little arrow next to the mute button) to open settings. Both give you the option to choose which mic/speakers you want to use and both allow you to do a test record for a few seconds and then have it played back to you.

I know in Webex you get this option before you are connected to the actual meeting, but Zoom may have it somewhere else I haven't bothered to look for. I make a habit of testing my mic every time I connect to a meeting, just in case I mucked something up or there's some other issue I wouldn't have known about. It's a minute of checking to save several minutes of embarrassment and delay later on.

Using the Zoom "record in the cloud" feature should roughly correspond to how people hear you BUT it does not let you know if eg your setup echoes someone else's voice. Bother someone, find a friend, ask your manager, geek out about audio, something.
There's a way to launch a "test meeting" where you can hear yourself as others would: https://zoom.us/test
Just listen to your own audio? In windows there is a checkbox for this, and most call apps have a settings page where you can listen to your own mic.
Not really. Zoom applies lots of noise canceling and other filters, so your raw audio doesn't correspond to what you actually sound like to other people (unless you use "original audio").
> they still never bother to get a decent mic.

one more damn thing to get

one more damn thing to research

one more damn thing to fit into your budget

one more damn thing to acquire that you maybe hope to never ever use again after the Year Of Videoconferencing is over and will have cluttering up your life forever after unless you find someone to pass it off to

(if you are really passionate about it: cut the gordian knot of all those problems by convincing whoever holds the purse strings that it would make all these interminable meetings much better if everyone had a nice mic, and get the company to buy a bunch and send them out.)

It baffles me that some people don't seem to care about their audio quality on calls.

Here's the thing about perception: A lot of it happens without your conscious knowledge.

One of the things about using Audacity as one's cheap studio software, is that you have to adjust for recording latency for multitrack. It's really easy to see how a part of perception is unconscious with the delay.

Almost no one is going to notice 5ms or below. At 20ms, many musicians are going to have this definite sense that something is off, but they can still hang. In between, it's a spectrum.

In order to introspect enough to notice things that are below conscious perception, some people require some training. This is also why audio snake oil works.

I use the wireless ModMic myself.

> Almost no one is going to notice 5ms or below. At 20ms, many musicians are going to have this definite sense that something is off, but they can still hang. In between, it's a spectrum.

Reminded me of this article, easily one of the top 20 I've ever read (Brian Eno, Francis Crick, Italo Calvino, roller coasters, trepanation, time, death, drumming)

https://www.newyorker.com/magazine/2011/04/25/the-possibilia...

> “I was working with Larry Mullen, Jr., on one of the U2 albums,” Eno told me. “ ‘All That You Don’t Leave Behind,’ or whatever it’s called.” Mullen was playing drums over a recording of the band and a click track—a computer-generated beat that was meant to keep all the overdubbed parts in synch. In this case, however, Mullen thought that the click track was slightly off: it was a fraction of a beat behind the rest of the band. “I said, ‘No, that can’t be so, Larry,’ ” Eno recalled. “ ‘We’ve all worked to that track, so it must be right.’ But he said, ‘Sorry, I just can’t play to it.’ ”

> Eno eventually adjusted the click to Mullen’s satisfaction, but he was just humoring him. It was only later, after the drummer had left, that Eno checked the original track again and realized that Mullen was right: the click was off by six milliseconds. “The thing is,” Eno told me, “when we were adjusting it I once had it two milliseconds to the wrong side of the beat, and he said, ‘No, you’ve got to come back a bit.’ Which I think is absolutely staggering.”

I also go to a game developer meetup. This developer was actually delaying all of the players, so that 40ms was their typical latency, no matter what. The developer had done some research with his multiplayer game, and concluded that most people didn't notice under 40ms round trip.

Some of the hardcore FPS players in the group could definitely tell!

10ms is 3m, thus e.g. in an orchestra, 20ms latency is normal.
Yup. 30 feet or 10 meters is about the limit for comfortable improvisation. Really large orchestras can require musicians to compensate. I had to do this once when my school's band joined up with a National Guard band to form a huge orchestra for an 1812 Overture. (With actual cannon!)
It baffles me as well. Especially because I do get feedback like wow your voice “carries”, or it is clear, or that it is “calm”. The best comment I received was that it sounded like I was there in the room and that it captured my voice well. Related to the OP my voice also has been called convincing.

This is with a beyer dynamic microphone extension for a studio headphone. And I have the gain fixed.

Everyone else in our comp keys team sessions has keyboard sound, plops, distortions. But in general it pretty well understandable at the cost of having to spent effort to understand. So maybe software is doing a hell of a job here.

The most difficult part is testing how you actually sound for other people. The software can do whatever to the signal coming out of your machine.
You are wondering why people who prioritize something else "don't care about audio quality"? Remember open offices? The likely culprit for them going with noise canceling headphones? Yeah they still have their old gear and are accustomed to it and the form factor.

Philosophically it is also why would you go with something big and cumbersome for a feature you seldom use? You don't carry a glass bed scanner in your laptop bag - you take a photo if you really need to get a digital copy of a printing. Plus not all are equally enthused or know how to filter through the crap without a large /in person show room/ that would be either filthy or a pain in the ass to disinfect before a pandemic.

Not helping matters are audiophiles being infamously placebo connoisseurs and walking proof that it is easier to fool someone than convince them they were fooled. That market is flooded with bullshit and specious claims so the default assumption for people claiming you need new more expensive audio equipment has been "ignore them, they are gullible idiots who think you need gold cables for digital connections to reduce low level noise for digital signals".

> You are wondering why people who prioritize something else "don't care about audio quality"? Remember open offices? The likely culprit for them going with noise canceling headphones?

Exactly that. I've been working for 5 years in more or less noisy open offices. Some of them so noisy that there were regular arguments between the self-proclaimed quiet ones and the noisy phone callers. I followed this with amusement.

So yes, it is quite an exaggeration to now ask for Hifi audio quality during meetings. Apart from that, I think a little noise makes the lockdown in the home office a bit less boring, the majority of people worked on-site before the pandemic.

> It baffles me that some people don't seem to care about their audio quality on calls.

1. It is a bunch of extra work and expense for something I probably do not really want to be on. Easy audio communication is bound to induce more audio communication.

2. I have to maintain a bunch of infrastructure for it, manage configuration, and deal with all the wires. It is far from a free and easy improvement.

3. I rarely speak in meetings anyway.

> Easy audio communication is bound to induce more audio communication.

Alternatively: if you you are going to be hassled with an online meeting, get it over with quickly and with the least stress. It is very slow and stressful to fumble around with “Can you repeat that?” or worse, people not mentioning that they didn’t actually understanding you and then dragging out the meeting with their misunderstanding.

“If you have to eat a shit sandwich, take big bites.”

There are very good USB mics like the Blue Yeti for example. Plug and play with just one cable. You don't have to have a studio recording setup to get your voice to come through nicely.
The Blue Yeti is an okay mic, but is a little pricey for what you get and also buys you into some other stuff you may not want to spend the money on, like a bit of a heavier-weight arm, etc. to be close to one's mouth. It's also a little sensitive for spoken word and while it can sound great in a treated room it's not great for conferences or untrained users due to its habit of picking up a lot of ambient noise through untrained positioning or habits (drumming on a desk, that sort of thing).

Most folks I know recommend the Samson Q2U or the Audio Technica ATR2100 instead as easy mics to deal with for untrained users; shameless plug, but I wrote an article for Mux about this not long ago which explains in some depth why one mic may be preferable to another for untrained users: https://mux.com/blog/zoom-like-you-mean-it-1/

I wouldn't get a Blue Yeti for voice calls. Besides being pricey, it's a condenser mic and a lot more sensitive and prone to picking up other sounds you probably don't want.

Something like the Audio-Technica AT2005 also supports USB plug and play, is half to two-thirds the price, and is a dynamic mic so will reject a lot more of the undesirable sound before it even gets into the computer.

It's easier to not capture undesirable sounds than it is to try and clean it all up after.

And come appraisal time you get marked down, your peers will have possibly negative opinion of you.
> The ModMic is also excellent

I have a ModMic 4 and I am disappointed. I used it for voice calls with my Sennheiser Momentum headphones.

- Accidentally pulling on the wire will cause it to turn on the magnetic handle and create unpleasant noise for others. - It picks up signal from the phone trying to connect and transmits it to the listeners as buzzing sound. So I had to put my phone far away to avoid that. - The mute switch does not really mute, it’s more like turning the volume to 10%. Learned that the hard/awkward way. - Sound quality is mediocre, to me it always sounded like any generic mid-range headphones+mic combo.

If I could test ModMic before buying it, I would pass. I’d rather put the money towards a standalone mic (e.g. yeti) + boom arm. It’s expensive, but the quality is way better. I now use Røde PodMic with Scarlett Solo. It’s whole other price tier, but I do not regret spending that money, which I cannot say for the ModMic.

> It baffles me that some people don't seem to care about their audio quality on calls.

They might care but have no idea it is bad. You can’t hear yourself on a call.

I absolutely love my Bose QC35s. With the modmic that I attached to them. When using the mic built into the Bose QC35s it switches to mono audio, and the mic itself is indeed also terrible. Very unfortunate.
Which mod mic do you use? The QC35s have the extra small plug so I thought most mod mics would not fit.
The modmic has their own little sticker that is stuck to the outside of the mic. That's what the modmic attaches to. If you have the wireless one, that's that. If you have the wired one, the 3.5mm jack goes into your PC, not into the QC35s. So it doesn't matter what kind of plug the QC35s have.

I actually have both a wired (very old, wire kind of broken because I treated it poorly) and a wireless modmic, and both work fine with my QC35s.

Has the modmic gotten better? I've had one for years and it has always sounded like garbage.
There are a bunch of different versions with different capsules. For example, the Modmic Uni doesn't sound very good, but since it's unidirectional (it's a 6mm cardioid electret I think) it is rather more resistant to ambient noise. The Omni has your usual run-of-the-mill 6mm capsule, these are all very similar in terms of sound and noise performance. The Uni is kinda good enough for pure communication, but you'd really wouldn't want to use it for content production.

Also, being electret capsules directly wired up to your soundcard, the soundcard has quite an influence on the quality of the audio (mostly in terms of noise and hiss). Meanwhile the digital versions don't suffer from bad microphone inputs.

It depends a lot on your sound card I guess. Pro streamers use them on twitch as portable options (like Seagull) and they sound great to me.

The only real downside to it is the cable is sort of flimsy and the 3.5mm termination is not great quality. That's how my last ModMic perished, although it lasted a few years.

It also depends on positioning and configuration; having it directly in front of your mouth and/or having the gain too high are common problems I've run into.

As an aside, it's been interesting as someone who knows things about audio to realize how much I've unconsciously internalized that most people apparently don't know. Like more gain != more better or what a plosive is.

I got their wireless one recently and everyone I regularly use it to talk to immediately noticed the quality and commented on it. Can't speak to the wired ones.
In my experience AirPods have excellent mics for what they are. They're definitely a million times better than the built in mic on the various (high-end) phones and laptops I've used in recent years. I wonder how they compare to a standalone mic or a decent headset mic (or that ModMic you mentioned.)
AirPods have a worse mic than pretty much anything you can get. Macbook Pro's built-in microphone or Apple's $20 wired earbuds both have much better mics than AirPods.

I would suggest recording yourself using different microphones and comparing them to see how bad Airpods mic is.

Just did this. My AirPods Pro sounded a lot worse (very soft, muffled and way less resonant) than the pair of analog 3.5mm wired earbuds that came with an older iPhone.

I suspect it's because the wired earbuds had a mic near my throat whereas the Airpods' mic were up near my ears. The difference is very noticeable.

Looks like I'll be keeping my wired earbuds around for future conference calls.

Airpods can't compete with a decently priced boom microphone that actually comes close to your mouth. The distance from your mouth to your ear (where the mic resides) is quite long especially considering how little space they have to throw in a capsule into.

So, either you'll get a lot of ambient noise, the signal is quiet or Apple will do some algorithmic trickery that tries to approximate some kind of echo cancelation on the audio signal, but compared to a simple dynamic microphone that just has a more favorable position and form factor, it'll always lose.

Hmm. I just measured the distance between my Airpods and the corner of my mouth at 3" or around 7.5cm. Very approximate measurement, but it seems to be not far off of recommendations for where to place headset boom mics (google says 1-3 inches from the mouth.)

Also, it's worth noting what the goal is here. The aim is not to capture the most accurate sound period. I've had calls with people who clearly have very expensive setups, but I end up hearing pen clicks, keyboard sounds, breathing, swallowing etc. The Airpods seem to do a great job of making my voice sound good in general. I've gotten compliments on my audio (so it can't be that bad) and the Airpods don't seem to pick up my breathing, typing, etc so I'm happy.

ModMic(tm) is quite expensive.
I have found that many of the people who didn't shower in hot weather are the same people who don't care about their audio quality; I think it requires a certain amount of empathy for other people to realize how jarring and annoying bad audio is for the listener.

It's also similar to the anti-mask problem, frankly. Even if you don't care, you should realize that others do and not abuse them for your own convenience.
