Sound is OK, but so what. Take 2 hours to charge. I FEEL ITS BIT HIGHLY PRICED, AROUND ?2500 ONLY IT WORTHS. Prior to getting this I dropped case on ground and ear buds fell out as it is not magnetized like other buds cases. The quality is like less than $3If I could return it and refund it easily, then I totally would! Other than that, love this sandal! It adjusts in length easily, as the designer put both adjustment screws (one on each leg), facing the same side, which makes it quicker to adjust BOTH legs. Lots of room for adjusting. Given my love for my ES9s I was only buying Audio Technica and I was looking for over-ear and closed-back for comfort and isolation. Such a shame because I own the navy ones with cork bottoms and was looking forward to having white ones as well!
