Bin so far quite pleased! (Should change what I'll keep you up to date course ;-)
Pros:
+ Coupled easy & fast
+ Goes perfectly with all 5 (LG P350, LG L7, Galaxy S3 NEO, Odys NOON Pro, MacBook Pro Retina) devices tested
+ Clear stereo sound (perfect for listening to music), no (noticeable) sound - quality losses
+ Small price
Cons:
- Built-in battery lasts only about 2 hours
- Long shipping (St. Pölten, Austria)
- Sooo rare small dropouts, but not interfere with the further
Addendum of 15/03/2015
I am using the device continues to be satisfactory, the built-in battery is now scrap now depends increasingly on the cable, which does not bother me ...
