Got these last week. Just like to say they are the most comfortable iem's I have, the sub bass is awesome without any detrimental affect on what is a pretty detailed and balanced sq. Build quality may be a future problem as cables are a Little thin, strain relief is good though. Never had an other in-ear that is so forgiving of fit/sq. micro phonics are a little above plastic cable items, but over ear is comfortable and removes this problem it also brings the mic/remote to a more favourable position.
Overall would recommend to anyone (rare).
Purchased for £40 Belfast apple store.
Really cool. The depth of the fit certainly seems "adjustable."
