It's definitely a bit quiet, but I just jack up the volume on my laptop/phone and it works fine. Note that because of this, it might not be good for noisier environments - I've only used mine in a quiet environment, and I don't know how loud it will go.Otherwise it's been great so far. Given that it's only 16 bucks, I'd say I got my money's worth.(Note that it only comes with ONE earpiece. I didn't realize this at first - was surprised when I opened the box and there was only one, but went back to the product page and saw that was indeed correct. I've actually ended up liking only using it with one ear, so it's been fine - just make sure you realize it's 1, and not a pair.)EDIT: had some issues using it with iTunes, but it seems to be working now. I found a setting somewhere in iTunes along the lines of "Sound output", where the options were "Windows Audio Session" and "Direct sound". I switched it to "Direct sound", which necessitated relaunching iTunes, and that seems to have fixed the issue. However, I don't know if perhaps just the iTunes relaunch was what fixed it; I read on a forum somewhere that others have had a similar issue, and just relaunching iTunes fixed it for them.More experimenting to do, I guess.At any rate, still 4-star worthy, since it (so far) still works with iTunes.EDIT 2: no further issues with iTunes or anything. Upping my rating to 5/5 stars (from 4/5 previously); great little earbud, couldn't be happier!
