BOYA BY-K3 TRRS 3.5mm to Lightning Audio Adapter

TRRS Microphone Adapter for Lightning

The BOYA BY-K3 converts a 3.5 mm TRRS microphone or headset plug to a Lightning connector for iPhone, iPad and iPod Touch models that lack a headphone jack. Apple MFi certification guarantees full iOS compatibility without error messages. The 10-gram dongle supports sampling rates up to 48 kHz for clear audio capture. Inline controls handle volume, track skipping and call answering.

For Mobile Recording Not General Listening

Content creators who plug a lavalier, shotgun or headset microphone into an iOS device get a direct digital path with noise filtering. Users who only need stereo headphone playback should look elsewhere because the adapter must be unplugged before audio can be heard through the device speakers. It also does not add a second Lightning port for simultaneous charging.

Steady Performance During Long Sessions

MFi authentication keeps the link stable across iOS updates so extended interviews or livestreams do not drop connection. The fixed 10-inch cable avoids the intermittent contact that plagues shorter dongles under movement. Heat stays negligible because the adapter draws minimal power from the Lightning bus. Audio quality remains consistent at the rated 48 kHz sample rate throughout the session.
