Does not work with Grandstream ID phone with Android

Unfortunately it is not possible, the ARCTIC P324 BT to the Grandstream GXV3240 IP phone to connect properly, although the phone runs on Android. The microphone volume is too low and you can adjust the apparently nowhere. An email to the support of Arctic remained unanswered. Because of the lack of support there is only one star. On my smartphone I could connect the device as a headset. Disadvantage there: you hear in the headset amazingly loud own motion noise caused by the past underline the hair on the bow of the headphones and these sounds are transmitted through the frame to the Ohmuscheln. No buy recommendation.
