Slim Connector Design

The Onyx Series cable uses a bevelled step-down connector that measures thin enough to fit through most smartphone cases. This allows a secure 3.5mm TRS connection without removing protective covers. The 3.00 ft length suits desktop or portable setups.

Build Integration

Two gold-plated 3.5mm plugs connect a source device such as a phone, laptop or MP3 player directly to headphones, speakers or a mixer. The slim heads free up adjacent ports and reduce strain on device jacks. No adapters or power are required.

Wired Stereo Users

Buyers who need a durable, case-friendly auxiliary lead for analogue stereo audio will appreciate the 5000-cycle bend rating and aluminium shells. Users requiring balanced audio, longer runs, digital transmission or multi-channel output should consider other cable types.

Questions about this item

How does the 3.00 ft length limit placement of connected devices?

The cable spans three feet, so source and destination must sit within that distance; plan device positions before routing.

Will the aluminium connectors and gold-plated plugs stay cool and quiet during all-day playback?

Passive copper conductors generate no heat or noise; the metal housings simply resist corrosion and physical wear.

Which devices must already have a 3.5 mm TRS port for this cable to work?

Both ends need a standard 3.5 mm stereo jack — smartphones, laptops, mixers, headphones or powered speakers with that socket.
