A:AnswerI am not 100% sure but I do not believe you can purchase just one. They are sold as a pair and if you need service on any one of them Bose wil replace them both.
A:AnswerYou won't get a chance to sweat in these, they won't work for long enough from my experience. After a week of owning them the right 1 crapped out and is unresponsive to every trick I have tried. 200 dollars for a marketing wank... I feel... used more than these almost brand new headphones.
A:AnswerYes!! I use these when I’m mowing the lawn and it’s really incredible how much noise is blocked when noise cancellation is at full strength (10). Can’t go wrong with these!
A:AnswerYes. There are different levels of the noise canceling feature. When I need to hear my surroundings, I don't have them on max. I use the maximum noise canceling at night because my husband snores and they COMPLETELY drown out the sound and I'm able to get a good night's rest.
