The only way to get it to connect was to put the left piece back into the case to turn it off and try again. The label on the packaging definitely says "Headphone - Blue". - Doesnt have AUX input. I?ve had them for over a month and have tried to (lightly) stretch them out over time but they rub my ears practically raw from use within 10-15 minutes. Ties had to be folded in half 2x to fit. This is a very nice, inexpensive upgrade for table saws with cheap, unreliable miter gauges. They seem to fit a tad smaller but I absolutely love them for support, durability and they offer great comfort. Because they are waterproof i can wear them confidently when i exercise , or if it rains while i am outside. I highly recommend them, and IF they ever wear out, I will definitely buy another pair! Discovered Glerups in 2017 and will be a customer for life: Theyve fast become an essential creature comfort and I even travel with them.
