Lost mine after a week. Pain free. Ok I love this thing! In UK sizes Im a 6. When these first arrived, I was worried because the soles were thinner than I was used to. I hope the next generation of these with bluetooth 5. Less harsh in uppers compared to the original HD800 while retaining its clarity and sound stage. Works great with Google Assistant as well. I love having the microphone, however it scratches against your clothes and is hard for people to hear you. The sound is great and the bass is good, I really enjoy it.
