Compared to cable headphones,

So the sound is perfectly fine, apart from the quiet time noise on the right side.

With the appearance I am completely satisfied, beautiful black and white contrast.

One point with which I am not quite satisfied is the wearing comfort.
If they are also times longer (about 1 hour) will wear the piece,
are they really uncomfortable and you get from the outside earache.

Installation on the iPod and on the phone worked fine.

And of course, the Bluetooth transmission is really handy,
works fine.

What I do not like that, is that if the battery is low,
every few seconds an annoying beeping sound when you use them.
This makes it impossible, then continue listening to something.
A flashing light would have been more practical here.

So, overall, I'm so happy, but:
I've also used wesc Cable headphone the same price range,
and I have to say are better in almost all respects:
Better sound, more comfortable to wear and also visually better.
But just the inconvenience of cables ...

CONCLUSION:
Actually, good price / performance ratio.
However, if you a flawless headphones expected
you have to give up the Bluetooth either
and buy a cable headphones,
or if one is on the Bluetooth, definitely invest more money.
