6.35 mm to 3.5 mm TRS Adapter

This gold-plated adapter converts a 6.35 mm (1/4 inch) male jack into a 3.5 mm (1/8 inch) female socket. It lets you plug standard headphones or microphones into professional audio gear, amplifiers, mixers and receivers. The 3-pole TRS wiring carries a stereo signal without modification. It is a simple, passive solution for connecting consumer audio devices to larger jack inputs.

Capacity and headroom

The adapter handles the full analogue stereo bandwidth that the connected equipment provides. Signal quality depends entirely on the source and the headphones used; the gold-plated contacts resist corrosion to maintain a clean path. It adds no amplification or processing, so dynamic range and impedance matching are unchanged. Users needing balanced mono or multi-channel connections will find this two-conductor-plus-ground design insufficient.

3-pole TRS wiring

The single specification that decides compatibility is the 3-pole TRS (tip-ring-sleeve) configuration on both ends. This matches standard stereo headphones and most consumer microphones with a combined plug. It will not pass a separate microphone contact found on 4-pole TRRS headsets, nor will it carry a balanced signal required by some professional line-level gear. Check your device plug count before buying.
