The only fault I have with them is due to my high arches, which make the elastic strap a bit tight, but Im hoping it will stretch over time. Looking back at my Amazon purchasing history this is at least my 7th Bluetooth speaker purchase. Y’all. Out of the box the detachable ear piece is not working! When Im listening to pop, its usually stuff by Nick Cave, Greg Cartwright, or Jason Molina (RIP). I absolutely love these and am looking forward to another comfortable summer looking good! It is adjustable, but even the lowest position provides ample stretch. My voluptuous feet were hanging off the side and it was squeezing the life out of my little piglet! For what I bought them for, they are worthless and without Amazon’s awesome return policy, would have been a complete waste of money. I usually where toegoz but could not find.
