Monoprice Inc. 7139 6.35mm TRS Plug to 3.5mm TRS Jack Adapter

6.35mm TRS to 3.5mm TRS Adapter

This adapter connects a 6.35mm stereo plug to a 3.5mm stereo jack, letting you use standard headphones with professional audio equipment. The gold-plated contacts resist corrosion and maintain signal integrity across the connection. Model 7139 is built for straightforward stereo audio routing in studio or home environments. It suits musicians, podcasters and listeners who need to bridge different jack sizes without signal loss.

Simple Passive Connection for Mixed Gear

The plug-and-play design requires no power or drivers, so it fits into any signal chain between a source and a headphone or cable. Its compact form leaves adjacent ports accessible on crowded interfaces, mixers or amplifiers. The adapter handles stereo signals only and does not convert balanced to unbalanced lines. Buyers needing mono TS connections, XLR conversion or digital audio formats will need a different solution.
