This was an interesting read, but what to me personally is more interesting is how to prevent hearing loss over the years. I might be wrong on this, but I recall a hearing specialist advising me not to use earbuds at all, or at least limit the use to max 1 hour at a time. A dynamic headphones, such as the good old Superlux HD 681 would be "better" in the long term. (Not trying to advertise for that headphone, it's just one of the few that is cheap, good, and I can rewire myself and even add a plug so I can easily buy new aux cables). However I cannot wear my headphone longer than 6 hours without it getting annoying. And running with a big headphone is a big no, but than again, I'm nowhere near to running longer than 30 minutes in a row. Anyone who has his own thoughts on this topic? |
The issue isn't necessarily about all "earbuds," the issue is that many earbuds (including the ones included with Apple iOS products) don't seal the ear canal very well, so a listener is exposed to outside sounds in addition to sounds from the player. Since the outside sounds have a tendency to mask the sounds coming from the earbuds, the listener will often turn up the volume to better hear the audio material and therefore be exposed to SPL's that can cause hearing damage over long exposure times.
The advice to use something like the Superlux HD 681 is that circumaural headphones offer some (not a lot, but some) shielding from outside noise, so a user won't be tempted to increase the volume level as much. Active noise canceling headsets and in-ear-monitors (like Etymotics-brand) provide better sound isolation so that users can keep the volume at more moderate levels.
