As notorious readers of manuals, I first looked for such a and none found. The compatibility list I could not see the link, which can be found in the poor, enclosed safety instructions.
Also in the Fire Phones None Manual. Thanks to another review I knew at least that you can start and pause with the remote control by pressing the center button, 2x jumps a title before and 3x a title back. Volume controls with the upper and lower rocker switches.
So far so good - well, because the buttons work in conjunction with my Huawei Ascent P7 really impeccable! The voice search proves to be very well thanks to good microphone.
For sound: without the support of an equalizer, I would say rather dull to blurry. With the use of such shows the actual bandwidth of the headphones - because here are truly individual successes achieved. And this reflects in my opinion of a good hardware.
Center support audibly, basses raise no problem ditto the heights. Now I expect for the price not a high-end product, but I'm surprised how good the quality. No distortion, no oversteer even at higher volumes. That's good.
The fit for my relatively small earpieces surprisingly good and free of pressure.
Conclusion: Buy recommendation with a star deduction for lack of documentation.
