Product information

Description

Hosa GPM-103 is a compact gender changer adapter that converts a 1/4" TRS (6.35 mm) jack to a 3.5 mm (1/8") plug. Finished in black, this adapter provides a mechanical and electrical connection between professional audio equipment and consumer devices, enabling the use of headphones, instruments or other audio products with mismatched connectors. The adapter is designed to adapt a mini stereo phone plug to a stereo phone jack and is suitable for studio, stage and portable audio setups.

Advantages

The adapter offers a simple and reliable way to join devices with 1/4" TRS and 3.5 mm stereo connectors without soldering or complex cabling. Its compact form factor and black finish make it unobtrusive in both live and studio environments. Because it directly converts the plug size while preserving stereo wiring, it is practical for headphone use and other stereo signal applications.

Suitable for

Converting headphone plugs from 3.5 mm to 1/4" TRS on amplifiers, mixers and audio interfaces
Connecting consumer portable players or smartphones to professional monitoring equipment
Using consumer headphones with instruments, practice amplifiers or stage gear that use 1/4" jacks
Temporary or portable audio setups where a quick connector adaptation is needed

Key specifications

Connector 1: 1/4" TRS (6.35 mm) stereo jack
Connector 2: 3.5 mm (1/8") stereo plug
Function: gender changer / adapter for stereo signals
Typical use: headphone and line-level stereo adaptation
Colour: black
Form factor: compact, inline adapter

How to use

Insert the 3.5 mm stereo plug of your headphones or audio cable into the adapter's 3.5 mm end, then plug the 1/4" TRS end into the target jack on the amplifier, mixer, audio interface or instrument. Ensure the connections are fully seated to maintain proper stereo contact. When removing, pull the adapter from the jack rather than pulling on attached cables to avoid strain on connectors.

Usage recommendations

Use the adapter for short-term or portable connections and when a direct, passive conversion is required. Avoid exposing the adapter to excessive force, moisture or environments with heavy mechanical vibration. For permanent installations or long cable runs, consider a dedicated cable with the required connectors to reduce the number of connection points and potential signal loss.
