Come my ideal very close

Comfort: I had been quite a few Bluetooth headset that had all your assets. But only in this one, I feel, nothing to wear on your head. No matter how I move, I feel no movement from the neck strap or the brackets on the ear. No feeling of slipping or flipping, even tying shoes (ie upside down) is not a problem. While jogging no luffing up and down; when cycling fast left / right look without slipping slightly from the ear. I wanted to use the headset into the shower because I have not thought of themselves change the T-shirt because I'm wearing it.

Duration: of course depending on the time of use; but I do not feel I have to charge the headset before leaving the apartment again "soon". Of course, the voice message is to activate the headset also a great help, the one tells the battery status.
Here is a small gripe, which is however not attributable to the manufacturer: on my G3 is theoretically shown the battery level after pairing as a symbol; only shows this always "almost empty". On my HTC One (M7) nothing is displayed - as I said not so bad, since the headset's "self-explanatory" :-)

Charging: I am very excited that it is a normal microUSB connector - no additional adapter cable or charging cables needed. The charging time is very short.

Volume: Rating "very good", if I bow slightly to my ear press is even a very good bass to feel and of course the volume as more sufficient.
Still "good" when I wear the headset normally
The problem is rather to my ear shape as to the headset; I've always had this problem with the headsets of this type. For me dei volume is sufficient, since I myself will sonication sufficient to bike (although I have the volume set on maximum).
As I said I forgive Again full marks because this problem is more likely to find in my ears as the headset.

Controls: very good if you wear no gloves with the fingers - you must be able to feel the small bump for the switching on and off and for volume control. Underlying much larger button for call answer / end and Player control is of course easier to take. I have no idea how it will be in the winter on the bike, but when I know more details I'll still write a comment :-)

The attached arm pocket is for me more of a gimmick, but from the Qualtiät still very good. If one of the neon yellow color disregards and used the bag, the phone will be securely protected. However, there fits a mobile device from the format of the HTC One (M7) pure (by the width ok, the length is close to the limit).

Conclusion:
I would buy the headset again, price / performance is given for me.

/ Supplement:
It is incomprehensible to me why a clue was nowhere to be found, it (Android) Plantronics are various apps and are also suitable for this headset.

The most important is the "Backbeat FIT Updater"; as the name suggests you can about the firmware of the back beats up to date and is automatically informed when there are new updates (the alternative way is to connect the headset to a PC). However, be connected to the update itself must connect the headset to a power source.
For my (yes very new) Headset an update was in fact already exist; one learns about the app also the exact contents of the update.
Incidentally, my above criticism is (symbol shows always "almost empty" as a charging stand to) addressed in this update.

The app "Find MyHeadset" sends one of three selectable tones to the headset, which thereby (hopefully) can be found. The prerequisite is of course that it is coupled with the mobile phone and also turned on. I have not tested it in a noisy environment and therefore can not say whether it is really helpful - but perhaps there are scatterbrained people who need the function often :-)

"Instant Meeting" I did not test, because I have no way of doing this.

"Plantronics Hub" shows, among others, the exact charge level of the headset (in hours and minutes), also can be a description of the headset (Keys) Click. There is also a FAQ with the name, the questions such as "Do not disturb: Reject" "How can I?" Comes in, "Voice commands" or "bracelet / Storage".

"Headset Battery Meter" allows the user to put two different widgets on the home screen, which displays the charge level 4 25% -bar. This program was visually not very appealing to me and seemed inaccurate - at my fully charged headset three bars are displayed.
