A:AnswerYes. They wear out if you use them a lot. I have replaced mine a few times every couple of years.
I would advise getting the official Bose replacement part over the cheaper knock offs. You can get them from the Bose web site.
A:AnswerI don't know if they are listed as sweat and water proof but I have been sweating in mine for years and wearing them in the snow when I shovel the driveway.
A:AnswerI have used it in this capacity and it works. Be warned that on hot days when you sweat the ear pads can be damaged and can crack and flake off.
A:AnswerThese QCII 35 headphones are made in Thailand, helps keep the cost affordable, but the sound quality that BOSE is world renowned for is not compromised.
A:AnswerAs quit or as loud as you want I have never turned them up all the way so I don't know how loud they can get but they can go loud enough to hurt my ears.
A:AnswerThese work great as I have the exact same issues, the noise canceling buds also work amazing even outside in strong winds you’ll suddenly hear the wind go quiet and you’ll only hear the call
A:AnswerThere is only one adjustment to these so if you have a particularly narrow head the adjustments may not work. However, my daughter wears these occasionally without issue and she is 4.
A:AnswerWe have a Sony smart tv and we can connect via bluetooth to the tv without it muting the tv/sound bar volume. That way the wearer can control their own volume. Handy for when those that may be a touch hard of hearing to still get the volume they need without blasting the rest of the room!
