This adaptor converts the 4 conductor jack to a 3.5mm standard stereo headphone jack and includes a built-in microphone and answer button. This adaptor will allow you to use the built-in microphone for multiple reasons: to make calls, to use in an application (such as taking notes), or as a voice recorder/voice commander or skype.

Without unplugging it from your phone, this adaptor will allow you to have phone conversations. And with its integrated one touch button and built-in microphone, you will be able to answer and hang up on calls and then immediately return to your music.

The cable is approximately 14 cm long and comes with a standard 2.5 mm jack on one end that converts to a 3.5 mm female jack on the other end, allowing you to directly plug in any stereo device that has a standard 3.5mm audio jack, such as your favorite pair of headphones or headset.
