It’s made of leather, it’s sturdy, fits the Air Pod case well and has a strong carabiner. Overall I am satisfied and with purchase again. My original Tevas were adjustable across the back heel. The audio is crystal with good noise cancellation. As such, AVOID THESE DRIVES except for offsite backup purposes as otherwise you will have HORRIBLE issues with them. Using a reference such as Doug Macleods Exactly Like This album. The microphone capsule is HUGE. More suited for very small bodied persons, the heels are not sturdy Better than just a plain old slipper. It doesnt affect the headset in any negative way.
