A:AnswerIt will continue to play as long as the right and left are close, but the right headphone is the one paired to your device, so it would be best to wear only right if using only one.
A:AnswerThey can work with a Bluetooth TV. These headphones are more designed for sport, but you can use them for anything. I'd get a good pair of over the ear headphones with better sound quality for a TV.
A:AnswerThey have been in stock in-store in Boston area stores since before Christmas. Haven’t looked since. If you’re reading reviews you’ll see that I returned mine because connectivity was really poor even with latest firmware. You may have better luck than me however.
A:AnswerYou can do what you're asking with the right bud, but since the right bud is the one that connects with your phone, you need to be using that one.
So no, you can't use just the left earbud, but you can use just the right earbud.
I keep the right bud in my ear all day at work, only taking it out to charge, and I'll leave the left one in the charge case.
A:AnswerIf you are looking for a solid set of wireless earbuds, I would recommend these. They don’t have as many features as some of the other products, but for good sound and fit these are excellent.
A:AnswerI've tried playing tennis with my phone sitting near the net and the connection would sometimes go in and out when I turned my body (the receiver is in the right earbud). That's on an open court. I doubt you'd be able to get a solid connection through a locker and I'm pretty sure 75 feet is too far.
