The second tip thinner is a good idea because it placed on the kit does not fit my rather thin ear canal. With each other, the kit holds. You can add a small plastic support (supplied) for safety. Once in the ear, it is easy to forget with its light weight of 7.5 grams. The first time we sailed remaining supported above 4 seconds until the kit alternates flashing blue / red. The set appears under the name EP-B7. This is much faster on subsequent occasions. We remain supported two seconds on the kit and the smartphone is connected directly.
To answer a call, a very specific rings and the incoming number is dictated in English. Is pressed in the middle of the kit to take the call. The sound is clear, both for me and my partner. Similarly, pressed the button again to hang up. Two small buttons are located on the top (if you put the kit in the right ear or below if you opt for the left ear) to adjust the volume. By successive click it is adjusted. This kit also allows listening to music. The center button serves as a play / pause while the volume button changes the beaches (it remains pressed 2 seconds + to advance and - to go back to the beginning of the track and back). Although we must give up on the stereo, it can still help.
Discreet and effective, this kit has a rather nice look. It meets the expectations that we are entitled to demand of such a device. Personally, I use mainly by car (as long as it is still allowed!).
Pros: - Lightweight - Clear sound
Cons: - Small adjustment period needed before the movements become natural
