Quick overview


    • Record line-level audio from your mixer or soundboard on your iPhone, smartphone.
    • Allows your external audio output to replace your smartphone's mic. Includes attenuator that allows for line-level to mic-level conversion
    • Works with most phones that have a combined headset and microphone jack
    • Works with two audio sources at a time, just use a splitter!
    • Crystal clear sound recording, 100% guaranteed

    Our line level converter allows you to record from outputs such as a headphone jack or audio output jack such as a mixer or soundboard. Simply insert the male 3.5mm (1/8 in.) TRRS plug into your smartphone, and plug your source into the female 3.5mm (1/8 in.) TRS end of the Headset Buddy. The cable is approximately 13 inches long.

    How it Works: Plug the adapter into the iPhone (or other device) headset jack and then plug your audio source cable into the adapter. The iPhone will recognize that an external audio source is connected and turn its internal mic off allowing you to record using the external source. This adapter works with all audio/video recording apps and other functions just as the internal mic would.


    PLEASE NOTE: This adapter is NOT for recording from microphones. Also, sound input for smartphone connections is mono but most apps split the sound into left and right channels for playback in both ears. You are able to input stereo sound; however, playback will only be in the left ear.

    Q: Will this adapter work with a stereo audio source?

    A: The combined headset jack on the iPhone and other devices only has a mono mic input so you cannot record in stereo. Most recording apps split the mono signal into both left/right channels when recording so the audio will play back in both ears. You can connect a stereo signal to this adapter but only the left side will be active; if you use a stereo-to-mono adapter on your input cable then it will make both left/right channels combined and active. There is a new stereo microphone product available which will allow for stereo recording using the docking connector; this is currently the only option available for stereo recording, Tascam IM2 stereo mic.


    Q: Why do I need a different adapter for a microphone?

    A: The iPhone headset mic input is a mic-level input. The mic-level signal is much lower than a line-level signal which is used in audio outputs. This adapter has a built-in attenuator which reduces line-level signals down to mic-level signal strength. If you connect a mic to this adapter the signal would be reduced to a point that you would not be able to hear it in a recording. Use the MIC versions of this adapter for recording from microphones.


    Q: Can I connect two audio sources?

    A: Yes, you can use a standard 3.5mm splitter adapter to connect two audio sources which will combine the signals from both sources into this adapter. Alternately, you could use a small mixer to combine the signals from multiple sources into this adapter.
