The description indicated that they were a universal mount. They are super soft. These would not fit on my Hyper X Cloud headset as they are to small! Within 2 days - almost all dogs are gone. Good sound, but not what I expected from SONY. (Not like a hair piece. 100% not acceptable. I tried putting them in dryer to shrink and it left marks on the inside of dryer and size dufnt change. Well technically I was wrong. Im enjoying this earbuds/headphones because of the battery life and the sound quality.
