Hmm.... ich hab da was interessantes gefunden: http://allaboutwindowsphone.co…eadset_for_Windows_Ph.php
Ich zitiere:
ZitatNokia's first generation of Lumia products (Nokia Lumia 505, 510, 610, 620, 710, 800 and 900) have an AHJ connector, which is different from the OMTP connector used in earlier Nokia products (including its Symbian smartphones).
Nokia's Windows Phone 8 devices (Nokia Lumia 520, 521, 620, 720, 810, 820, 822, 920, 925, and 928) use a new universal connector, enabling the use of both AHJ and OMTP headsets.
Apple's non-standard signalling and control method means many designed for iPhone headsets are incompatible with other devices. In general the audio out and one button control on such headsets will work, but the audio-in (microphone) and volume controls will not.
Das würde ja bedeuten, dass eigentlich fast jedes Headset mit Lautstärkeregelung funktionieren müsste, inklusive dem WH-701 mit AHJ Stecker. Außer natürlich den Apple-Headsets.
