Following the announcement by Samsung in August 2014, I have been waiting to be able to buy it at last. I am when it comes to headsets, no fool. Have until now always the original headset of my Samsung Galaxy S5 used, which in itself is not bad indeed. The Gear Circle is to evaluate thoroughly positive. Included is next to the device itself, the appropriate charging cable (micro USB), 3 pairs of rubber for the earplugs, and 3 different sized brackets. In the mount bracket allows easy Gear press Circle in and take out. It acts on the neck not annoying, which I do not use the bracket itself. The comfort is also high enough so as the headset is very light. Go for a jog is the holder but certainly useful. To use the Gear Circle optimally, the Samsung Galaxy Gear app must be installed on the smartphone. (Requires min. 1GB RAM and Android 4.2.2) In addition to the headset can connect not only with the phone. Other settings can be made about Equalizer, notification settings, voice control and volume control. As reported in other reviews, the magnetic lock as start / pause music playback is. The button on the right earpiece, calls can be selected are angeommen and completed and the next song. Under the button, there is a sensor that will be used the volume control. The on and off switch of Gear Circle is on the inside on the left earpiece. The port for charging is covered by a flap. The headset itself is meticulously crafted and the cables are specially coated. Overall, I would to anyone who wants to buy a Bluetooth headset anyway to recommend this device. The sound is great, both listening to music and telephoning. The micro also seems to work well. My interlocutor said that I clearly understand even in background noise. The vibration for incoming notifications is clearly noticeable, but not too hard.
