I wanted to test the volume levels. The Velcro closure makes putting on this shoe so easy! I used these while I was mowing our yard without any issues since they are waterproof. Incredibly disappointing. They look like a little worried AI robot when theyre in the case and charged up. Buttons all function. Would buy again if I needed more shelving. They are more well-constructed than others Ive found yet still very reasonably priced. For my exquisite taste I enjoy the Bose Lifestyle 35, V30 and Companion 3. Very comfortable and great arch support.
