Overview

A passive stereo adapter that lets you plug standard 3.5mm headphones into a 6.3mm jack. Suitable for home audio, studio gear, and instruments.

Design and Build

The adapter features a 6.3mm three-pole plug on one end and a matching 3.5mm three-pole socket on the other. Contacts are gold-plated to resist corrosion and maintain signal integrity. The black metal housing provides shielding and durability for regular use.

Typical Applications

Use this adapter to connect consumer headphones or earphones with a 3.5mm plug to professional audio interfaces, headphone amplifiers, mixing consoles, or musical instruments that have a 6.3mm stereo output jack.

Connectivity Details

Both connectors follow the standard tip-ring-sleeve (TRS) wiring for stereo audio. The 6.3mm plug inserts into a 1/4-inch jack. The 3.5mm socket accepts a 1/8-inch plug. No active electronics are present, so audio passes through unchanged.
