Just get a wired business headset. No lag, no echo, great audio quality both ways.

When I know one of my peers made a sizable audio investment, as of then I pretend I can barely hear them.

I purchased a nice microphone for podcasting, and it works so well during work meetings that people will comment how much better I sound even if I forget to plug it in.

I second this. The cheap USB ones sound fine and never fail.

If I'm sitting at a desk at home anyway, I prefer to plug things in. Power: don't have to think about battery life or power saving modes. Ethernet: don't have to think about wifi. Headset: don't have to think about bluetooth, codecs, or battery. Keyboard: low latency, has followed me through four jobs.

I do use one of those wireless logitech mice, though. The AA battery gives it a nice weight.
