About TRRS & Smartphone Cables
Smartphones use a TRRS 3.5mm connection: three rings on the plug instead of the two on a standard TRS mini-jack, adding a microphone channel alongside stereo audio. That extra ring is why a standard microphone lead often will not work plugged straight into a phone, and why a purpose-made TRRS cable or converter lead is the fix.
The range covers TRRS to TRRS cables for linking phones to TRRS-equipped gear, TRS female to TRRS male adapter cables from CKMOVA and COMICA that let a standard camera microphone, such as a lapel microphone, record into a phone, and a SWAMP TRRS splitter that breaks out separate mic and headphone plugs. Smartphone to dual RCA leads from SWAMP, KLOTZ and Mogami play your phone straight into a mixer or stereo, and simple 3.5mm aux leads live here too, alongside the wider audio link cables range for 6.35mm and XLR connections. Phones without a headphone socket can use a smartphone audio interface instead, and plug-shape mismatches are usually solved with a small audio adapter.
TRS (tip-ring-sleeve) carries stereo audio on a 3.5mm plug and has two black rings. TRRS (tip-ring-ring-sleeve) adds a third ring and a fourth conductor, carrying stereo audio plus a microphone signal. TRRS is the standard for smartphone and laptop headset sockets, so an aux cable with mic support is a TRRS cable.
If the mic has a TRRS plug, it connects straight to the phone's headset socket. Standard TRS microphones need a TRS female to TRRS male adapter cable so the phone recognises the mic. Phones without a 3.5mm socket also need the maker's USB-C or Lightning headphone adapter, or a smartphone audio interface.
Yes. Run a 3.5mm aux lead or a smartphone to dual RCA cable from the phone's headphone output, or its headphone adapter, into an aux or stereo line input. Keep the lead short and set levels at the mixer rather than maxing the phone.
