I take a size 9 in shoes and these are the size 8-9 slipper. So I needed a super shoe. If I need to adjust volume I either click top or bottom of the controls. I really struggled to find a headset that could be worn all day and could easily transition between music and calls, but this is it! It’s smaller, fully waterproof, battery is great, and the overall design has improved dramatically! The cable is nice and soft. Ive never had Adidas sandals before. Oddly enough JBL’s website doesn’t mention this fact in the specs. This is the best Design and Quality belt I ever ordered or used. Instruments are more reasonably positioned, offering a more comfortable sense of space.
