Update: After two weeks of sporadic use, the device can hardly be heard from the receiver, both indoors and outdoors. I threw the box away so I'm not going back, I think the only thing it will be useful for is listening to music while I walk the dog. Keep your expectations low here, they pay for 5 star reviews. I used to give 4 stars (my reviews don't sell) but I'm giving it up because of the quality and many others may not be updated since the device was in the zero bag. -------- old test report ---- ----Good: The noise reduction works very well indoors. Easy to put on headphones. The sound quality is good. The battery life is excellent. the end. Driving and indoors was not a problem. Overall, this is a great device that serves its purpose for remote work. I'll keep it and make sure it's just a desktop device so it doesn't get disconnected from the charging cable.
