jeez they've missed a few key points. Sound is 10/10 and I loved my Bose soundsports. Was very excited to get these. Ok - sound wise - best ever. Comfort in-ear - crap. Everything ear comfortwise supplied is crappy, either bad comfort and they fall out. So then the additional $45 to get the comply's recommended...well if you do any exercise, these are not good. Even a walk around the block will have you pushing them into your ear. It is incredible that this important element of sport headphone has been so underdone, BTW the Bose never were never noticed in-ear doing walks, MTB riding and running. The Bose sound its really good, but a level below the B&O's. Ghosh the BEO's sound quality covers a lot of deficiencies. So if you love a lush sound, stay at your desk and make lots of calls (you can charge em and keep charging while making calls which I love) is a great function. If you're a sport head, there are better options. Ah, it's a compromise - the best sound or better convenience.
