Samsung Smart (phone) control. From the comfort and sound pleasure at that.

Control specializes in Samsung devices, which is probably the most important thing you should know before making a purchase. On the product side, however, is "Yes, with most smartphones and portable players compatible." - I can see that is definitely not so, at least I have "control" quite a few tablets and smartphones, but in my household is allowed only the Galaxy Notes, the new Samsung Galaxy S6 and the Ativ S. -> Blackberry, Acer, Kindle Fire ? -> None. ;-(

What I mean by that?
The mini keypad can i put my Samsung (for example my smartphone the AtivS) optimally control:
- Answer / end phone calls
- Start voice control and thus ...
- Start phone calls or
- Start Search or
- Settings --- in short: Everything else fumnktioniert about the voice control can also these earphones.

(+) Sound quality is impressive!
(+) Ambient noise quite minimized and without that you can full speed * turning up as music on *.
(+) Comfort is without doubt the best I've ever had at In-Ears. (Three sizes are supplied silicone essays, I take the middle and get along well with them.)
(+) Cable length and quality is equally without any complaint.
(+) Practical clip clip still helps to fasten the keypad / microphone on the lapel or collar.
(++) One small bag (unfortunately with Velcro) is super convenient for storage - that alone I could be a very big thank you and praise sing because me this bag just super super like.

NEGATIVE:
(-) Why but with this headset only Samsung can control devices is beyond my knowledge. I use a variety of handset or comparable headphones (the not do anything else in principle) and that this handset can take at least talks on phone / hang up and adjust volume.
With this headset from Sennheiser happens on many devices nothing, that is at least volume can not settle on the button on the control panel itself -. While the headphones transmits the sound must regulate to the volume but the device itself and the central control knob shows, for example, on BlackBerry no benefit for calling and not volume ... which I thought was very disappointing.

In summary:
(+) Tested positive ... I have on the Samsung Galaxy Note Smartphones and especially my AtivS (Windows Phone 8.1).
(-) NEGATIVE was the test on BlackBerry, Acer Tablet and Kindle Fire Tablets all.

Well, what I would say is difficult to * only "good or * only" bad sum.
I recommend anyway care when choosing --- especially if you want to control something other than Samsung so, you might be disappointed. If you want to use Samsung Smartphones / phablets / Tablets so that it is the first choice not only for sports applications.

And moreover, you should decide which ear shape is chosen also because Sennheiser offers this model with different ear-fixing mechanisms to:
