o Great quality and directional hearing. so easy to wash and wear! You do not feel every stone you step on. Initially we didn’t like this product. I suggest ordering the next size up, as these are too small. I was hesitant because these seem large, but because of the changeable ear pieces they fit perfectly. It sure beats having to borrow my neighbor’s phone to call my phone and track it that way! The TT defaults to no quartz lock when its first turned on, so your speed will be out of kilter first thing when you turn it on, if the control is off the detent. I couldnt be happier and I am one particular hard to please shopper. Tried to call was transferred to a vm saying basically not checking VM.
