This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.

Ex Output:
Bad review

I own and use a variety of different headsets for work in the real world but this particular device just does not cut it. It's uncomfortable, doesn't have enough power, is very difficult to hear, makes voice recognition really weird & it feels cheap as heck. The best thing about it, aside from its size, are it's battery life. I'd pass on this, get one that actually meets your needs or buy something more expensive so you don't feel like you've thrown away money.
