The only downside, for my taste: the volume. I have it from time to time like a little louder and with these parts that's only possible when connecting it to a device with a large volume level. Pleasantly not, not too soft, too loud: For me, the iPod volume at the variety remains. But if I want to loudly I look through your fingers. But what makes the whole bet is that those things so well foreclose the outside world that you have to have no worries, mitzubekommen nothing of the music. So you just have to settle really to be able to entertain, for example, can. I have already had several headband headphones and it's not walk and add that this noise reduction is working so well.
For 30 euros, please, what more could you want. Really solid and good headphones with great sound. I tried once to compare Beats phones and can find no huge difference to the volume and there are still 200 Euros time difference. (And please Hipsterkinder, not scold me, because I have now ventured to say)
