For sound:
Who wants Analytic earphones which probably remains a AKG K3003 not spare to more than 1000, but who just want to have fun with music (regardless of direction) is with the headset right. The bass is ausgespägt but not too much (which you can change with various equalizer options). The heights are accurately reproduced.
It's just the typical AKG sound in a small format.
For iPhone control and microphone:
Since the AKG page omits this information I will inform about:
The fact that they work on Apple devices, is clear, but what is to Android devices?
I have to say on my LG Optimus 4X HD it is not working. But the app "JAYS Headset Control" fixes the problem. After their Configurati, they can be controlled Control as an ordinary "1" button. This however can only use the middle button, but since it is just Android.
Also, the microphone can be exploited, since I started using this app.
Criticism:
For the price metal would be attached to the connector that any cable breaks and the like does not happen. Also nice it would be if it were not for the groove between the cables of the individual listener, because (at least for me) accumulated while working in the grinding metal dust in it.
Despite the few, for me quite important criticisms, I can recommend this headset fully all Apple and Android users. I would buy it again and again.
