Behringer BH470U

After a few months of using it, I have almost no complaints. Sound quality is superb for this price, the microphone is passable (although it does not work with the Android phones I tested, for some reason the system mis-detects the headset as speaker-only and can't be convinced otherwise).

My one gripe is that the rubber covering of the gooseneck is not very sturdy and started to break from flexing it into place, but that's probably expected.

I haven't used the USB adapter too much so I won't be commenting on that, but it does work, except the volume/mute keys have a few gimmicks (mostly tested on Linux, so they might work better with Windows).
