Exceeds my expectations. The sound quality is excellent, on par with Beats (but less boomy, which is a good thing) and wearability is perfect. Very solidly build. I use it at work and during workouts.
The only annoying thing about is that, when moving (like on a bicycle) there is a lot of wind noise...but this is common with most on-ear headphones, and has nothing to do with the design of the Jabra.
I would buy a replacement without second thought if this unit were stolen or in someway damages (which would be my own fault, because it it's build like a tank)
