For something so dinky it really feels like a premium product. You would think one of the smallest mice Zowie could offer could fit that niche better since theyre all about hand-size/grip variety but I must say theyre lagging behind the competition. I dont feel the shoes are slipping i guess i am just so used to having to tighten them up to get them snug i keep looking for that set of holes. Bottoms are extra soft foam. Good sound, but not what I expected from SONY. Also the bass response is out of this work, spoke by an audio engineer! Great headphones, I enjoy the sound. It came out the box charged and it charges with USB C (thank god). These set next to the ear, not in the ear and they sound great! They are very comfortable and durable.
