One 3.5mm Jack for Both Sound & Microphone
This tiny audio adapter combines both stereo audio OUT and microphone IN into ONE single 3.5mm TRRS jack, and is specially designed for your wired headphones with inline microphone, such as Bose QC15/25 (for Apple Devices) or your phone headsets.
Therefore in order for both the audio & microphone functions to work properly, the plug of your wired headset should be TRRS CTIA standard.
- Tip: Left audio
- Ring 1: Right audio
- Ring 2: Ground
- Sleeve: Microphone
Note: Wired headsets with TS / TRS / TRRS OMTP plugs probably wont work properly with this audio adapter.
