A:Answer I have had 2 pairs of this model. I sleep in them, wear them on the boat (ocean), while I’m gardening, in pre-op, after op, during dental
appts, you get the idea. I have never had a break, just lost sound in lf headphone, which I still use, and why I bought the 2nd pair. Save the newer pair for out and about. Am here today to buy another pair for myself (just can’t get enough of a good thing), and a pair for my hubby (his first). He’s been very impressed with the sound quality AND the toughness of my headphones. Trust me, you’ll be very happy with these Bose headphones.
