Plantronics POLY BLACKWIRE 5220 C5220 USB-A

Excellent build quality, these are bit more slightly expensive headset but the sound quality is really great.

These have done a good job for me. I wear these for at least a couple of hours every working day for calls, and they are comfortable enough for that. They don't leak too much sound, and the microphone is good in not picking up to much ambient sound. I've had the first pair for over a year (I recently ordered a second pair for when these finally give up) and the only issue I have noticed is the cable coating degrading slightly, but I'm not exactly ultra careful with them to be fair, they do get knocked about a bit. To be honest I would have preferred a braided style cable, but overall for the money paid they are good.

Sound quality is good and the mic works fine, but not brilliantly comfortable on one ear when reaching 4 hours into a call centre shift.
