1. I can use for my Smartphone
2. the no cable has (Bluetooth)
3. can be used also during the cycling (helmet)
4. has a good sound quality
5. can be used as a headset for phone calls
In the delivery, the headset, a USB cable for charging and a storage bag contained. The delivery (ZBT) took place very quickly.
The headset complies with the expectations well and I saw him often in use. The sound quality is for my ears top, pairing worked without any problems (iPhone 4S), the volume sufficient for bicycle rides. Use the buttons is used to, then it works but good. What bothers me is the fairly bright blue flashing light (especially in the night), which probably should show the coupling.
The headset is comfortable and non-irritating, even after 3 hours of continuous conversation. By the neckband and the "Over-ear mount" are also head movements no problem if it is / was also an unusual (for me) wearing. The headphones dampen out the noise around enough (but not completely).
If the phone on the table, a room change (brick walls, about 5 m) is not a problem. One drawback I've found in the headphones so far, are disconnections when the body between the equipment and receiver (left pocket, right ear) is. It helps then to plug the phone into the right pocket.
I can not complain, I have not experienced yet on the battery life. Usually, I invite the headphones after use but also back on.
From me there is therefore: 4/5 stars, a star deduction for the disconnections in "incorrect" position and blinking.
