They feel great in your hands . I am forever losing my keys and my phone and this is the perfect solution to that. Im still dont understand why advertised as CL15. These shoes have convinced me to purchase at least two more pairs (different styles) for the manufacturer. If you want the battery option the unit will give you plenty of that, but your better off just to buy the backup battery as the headphone are junk, cheap, light, finicky touch sensor on the external of the headset. Ive only worn them twice now but so far am very happy. This shoe rack is perfect for the space I had. Another complaint I read was that one of the plastic clips broke. I?ve tried purchasing my cables elsewhere, but the coronavirus has put yet another plan on the sidelines. Lets not even get into how dysfunctional it is without this sound leak issue.
