Top positive review
Not Bad given all of the features and capabilities.
Reviewed in the United States on December 14, 2015
To set conditions, I was in search of a wireless (Blue Tooth) over the ear headphones that allows me to place and receive phone calls with a noise canceling capability for a long period of time. I acknowledge that it would be hard to find a headphone that provides the best of these features without breaking the bank. After a lot of research and this purchase, her is the quick down and dirty.
Noise Cancelation (the only reason why this gets a 4 star rating from me). The head phones do ok, though they do work in drowning out ambient noise (engines, air conditioning, etc.) they do have a "hiss" when the feature is turned on. Somewhat annoying, this "hiss" is seems to be too invasive and counterproductive to a noise canceling head set. Nothing spectacular in this area, Bose has this portion of the market locked in.
Audio: The sound is great. I am not an expert but I can tell that these headphones provide superior sound quality to many of the headphones with less options available. I am sure a trained professional can argue against me, but for an amateur, they are more that sufficient.
Phone Calls: The headphones are awesome in this respect. The accelerometers in the headphones answer the call when you place the headphones on your head. This is a neat feature that I did not expect to be as useful as it is. I know that some people reported the phone calls were not clear, I have not heard any negative remarks and test calls proved to be clear. I am sure that the Blue Tooth works great at 300 feet on an open football field, but in the house, it seemed to work "OK" between floors. There were times when it would crackle a bit, but the fix for this is to keep my phone in my pocket... too easy.
Comfort: I did not feel any issues with wearing these headphones for a long time. They are comfortable, snug, and they are not as heavy as reported in other customer feedback.
Battery Life: Awesome. Traveling for long periods of time, I am not concerned about the 24 hour battery life others may be concerned about.
Extra: You can (at the press of a button) hear what is going on around you. By pushing one button, the music stops and the microphones amplify sound allowing you to have a conversation, listen for sirens, etc. This is an added bonus I was not expecting.
I give it a 4 star only for the "hiss" that is somewhat counter productive.
