Most headphones Ive listened to, with on and off A. The dual plugin feature is handy, and I can plug into my PC, my Surface and my phone with the different plugs. My ears are not tired after the long use. Does not have any noise cancelling at all. Nice fabric and this purple color is very pretty (prettier than my picture indicates - lighting). They broke at the beginning of this summer. Was so excited to get them before my trip to Panama. After the latest Swarm update it crashes almost all of the time. Not a conventional use, I know, but meets the need PERFECTLY and at about the third the price of a compression vest via DME companies. Ive grown so attached and I cant move on.
