Am thrilled by the crystal clear sound and the wealth in sound. The noise, before me, many have warned there is not. (I'd hear, sounds with less than half a note value can differ, which is not always a blessing...) Popular songs seem to me as if I were in a concert hall. Seen in an absolute saving handset *; * To the unexpectedly great sound comes of comfort; very light and so hardly notice you're wearing, because I hear mostly about Smartphone (Samsung S3), before I can and choose back and skip the headphones title just pause and continue playing. Easily palpable are the buttons for louder and softer and the button to off and on. The petite but badly, could be that this is a weak point in long-term use. Even when switching off the headset and switch off the smartphone the music plays at the ear after switching both units at a touch of a button (continue playing) exactly up where I last stopped. It may be that nothing special is for experts - I am fascinated *; * The included cable makes the lack of radio function via Bluetooth bearable. Clever is that the Bluetooth controller can be set with the built-in battery separately to the charging cable while the earphone is not blocked. I just requested from Bose, if there is no such part as an accessory that would allow unlimited use (a part of the handset, a part when reloading). Property me a USB Bluetooth transmitter for using the handset also on office PC without (14.99 with USB 4.1) brought in to listen wirelessly to work. There are 7 hours of battery operation something little. , , The range of reception is indicated by 9 meters, but is limited at the latest while walking through rooms quickly. For the headphones are probably not developed. Normally I wear the smartphone or laptop with me - and who holds the connection stable. Should it break times, helps to reset or off and on rebuilding de connection reliably. (Takes 2 to 3 seconds, I had in two weeks intensive test two painting therefore is not an issue for me) All in all, I took the test phase while the right of return-intensive and was not disappointed. From me a strong buy recommendation.
