A:AnswerAbsolutely! They come with the cord/cable to connect to normal headphone jacks, and they still work nicely. If the battery is charged then the active noise cancelling will still work, and it's pretty nice when you're around others. I use this option on hand-held gaming systems, or when I don't want to connect to BT.
A:AnswerIf you are going to sweat at all, these are not the most comfortable. The ear pads are pretty tight to keep out ambient noise and help with NC. It gets hot and sweaty relatively quickly even when not working out.
A:AnswerThey don't really carry this model for some reason, but I found them online on their website when I was looking for their prices (note: I originally found them, and the deal on Amazon.com). I went in and spoke with a few employees, and they didn't really know why it wasn't stocked.
A:AnswerNot much leakage of music out ..and they do allow ambient sounds in if you dont turn them up too loud ..if your looking to drown out jet engine noise ..these will only do it 1/2 way
A:AnswerI'm not sure what Will is doing with their pair of headphones but these are good for about 20 hours of audio playback when using Bluetooth and with noise cancellation activated. That's at a listening volume of about 50%. I usually listen at 65-70% and they still last about 18.5 hours before needing to be recharged.
