These work well, although the mute button doesn't work on a Blackberry Curve. Solid and reliable, excellent for office conference calls. The cable connecting the two sides runs in a slot along the headstrap, and comes loose quite easily.

I actually bought this to keep in my car for safety on the phone. The headphones are comfortable and the sound is very clear. Love the boom mic feature. The price was fair for what it is. Got one for my wife for her car too.

my son loved this stereo headset

Quality is 3.5 stars because I am not sure how the headset's foam ear cover will hold up with use. I actually wanted the H390 for its over the ear material versus foam,BUT there wasn't a 3.5mm option with it. I don't want bluetooth.

Easy to set up and use. Good value for money
