I have the g930 from Logitech and they are okay, but I won't pick up another pair when these fail me (again).
The good and the bad: They are comfortable and their wireless range isn't too bad. I haven't had a problem with conflicting wifi. Sound quality is okay, nothing fancy and nothing spectacular.
As for problems... Well this is my third replacement from Logitech. First was a buzzing noise that took over all the audio and would take about 15 minutes of being off to fix. Next was the battery and it wouldn't charge more than say 20% and I couldn't go without an hour without it giving me a battery warning. The third and last replacement before Logitech told me to fuck off (still under even a single year) and the one I still have the battery is an issue. Lasting only about 5 hours (my original one went around 8-10 no problem before telling me I should recharge.
Other than that for the $80 I paid for these while on some sale they aren't too shabby.
TL;DR
I'd probably avoid wireless. Get that zalman clip-on mic and a good pair of real headphones.
