SSQ JSG3 is an audio adapter cable that converts a 6.3 mm (1/4") stereo male plug to a 3.5 mm stereo female jack. With a 3 m length, this cable provides a straightforward physical interface to connect headphones, earphones or portable audio players with a 3.5 mm plug to amplifiers, mixers, keyboard instruments and other audio equipment featuring a 6.3 mm input.
Advantages
The SSQ JSG3 offers a simple, durable solution for adapting between two common jack sizes without requiring additional adapters or bulky dongles. Its 3 m length gives flexibility for monitoring and stage use while keeping cable routing manageable. The cable supports stereo signal transfer for left and right channels and is compatible with standard unbalanced TRS connections.
Suitable for
- Connecting consumer headphones to studio amplifiers or mixing desks with 6.3 mm inputs
- Rehearsal and stage monitoring where a 3.5 mm headphone needs to plug into instrument or amp outputs
- Routing audio between mobile devices and audio equipment for quick checks or practice
- Temporary setups in home studios, classrooms, or small live-sound rigs
When it may not be suitable
This cable is intended for analogue stereo connections and is not suitable for balanced TRS professional connections that require isolation or line-level balanced wiring. It is not designed for digital audio formats or for converting microphone connectors that require impedance matching or phantom power. For long-distance runs beyond 3 m or when professional balanced lines are required, a different cable type should be used.
Key specifications
- Connector A: 6.3 mm (1/4") stereo male (TRS)
- Connector B: 3.5 mm stereo female (TRS socket)
- Cable length: 3 meters
- Signal type: analogue stereo (unbalanced)
- Typical use: headphone/line-level signal adaptation
How to use
Plug the 6.3 mm male end into the amplifier, mixer, instrument or headphone amplifier output that accepts a 6.3 mm jack. Insert a 3.5 mm headphone or audio device plug into the female 3.5 mm socket. Adjust volume levels on the source and destination devices before full listening to prevent loud transients. Use the cable in a straight run where possible to reduce strain on connectors; avoid sharp bends near the plugs.
What to consider before purchase
- Confirm your devices require a 6.3 mm to 3.5 mm passive adapter cable and not a balanced or digital conversion
- Check that 3 m length is suitable for your setup and stage or studio layout
- Ensure headphones or devices connected are compatible with an unbalanced stereo connection
Usage recommendations
For reliable operation, connect and disconnect the 3.5 mm plug while the equipment is powered down or volumes are reduced. Store the cable coiled without tight knots and avoid pulling on the connectors to extend service life.
