Where the swivel of the ear cups attaches seems like it might be a week point. The only headphones on the market that do it all: over-the-ear, Bluetooth, active noise cancellation, and volume limiting). I walked over 40 miles in these during a visit to Italy. Very good quality for the price. There are no instructions included with this kick stand however it is pretty intuitive. Secondly, I tried them on they were soft, snug, and felt like a ?Dream? on my feet I didn?t want to take them off! As is, I cant recommend these to anyone. After wearing both the E8 & E6 for a full day each I gotta tell ya, the sound quality is INSANE! I?ve heard some gripes about there not being much headroom for overclocking. NÃO COMPRE!
