I have the bluebuds for a week and was jogging with it, in the office and on the phone a lot. After adjustment of the setup to my needs (mainly sports) could begin already. In connection with my iphone 5 a class thing. Siri works, battery indicator in the smartphone, Volume Control, track selection, etc. The sound is really great and the processing also. The included accessories is extensive for adapting to your needs. Sizes: S, M and L. Setup is well explained in the manual and is slightly out of hand! Up to 8 Bluetooth devices can be coupled with the buds. He remembers all his partners. Top!
In the sport setup behind the ears can hardly noticed the parts. Nothing is loose or fall out. Much better than normal Iphone headphones.
Clutter was yesterday !!
Battery life: the real highlight! I really have spent 7-8 hours with the gizmos. Charging via micro USB goes quite fast in 2 hours.
And here we go again. I am very pleased! Delivery took about 4 days.
Can only recommend, even if the manufacturer in Germany is possibly not as well known, the headphones!
Much better than my old Bluetooth headset from Phillips.
