A:AnswerThey don’t have a noise cancelling ability. However they seal very well if you the right ear tip is being used, this works very well for blocking out sound in place of no active/passive noise cancelling.
A:AnswerSure, just push two times the beats bottom and that's it, also you can keep pushing the beats bottom and activate the voice command and ask for any songs you want.
A:AnswerI had to send mine back to Apple for this issue. Apple returned them telling me that they cold not reproduce the issue. I make sure they are on the charging contact and still have issues with them charging. Do a search on charging issues with these earbuds and you will find out a lot of people have the same issue.
A:AnswerAre you recharging the charging case fairly regularly? If so, track how quickly it drains. Apple has had battery issues with their products - as have other manufacturers. It happens…
If the charging case loses its charge to quickly, call Apple Support. If the set is still under warranty or you have AppleCare, Apple will honor it and exchange the case.
A:AnswerThey are sweat proof, so I feel as if the sauna would fall under the category of that since they will not be submerged in water. I think the only thing to be weary of is the headphones shutting off after to long of heat exposure, they will come back on after they cool down. I’ve used about 10 different headphones and earbuds, including water proof Sony, and this seems to be the case with them all.
