Audio extension cable DELOCK 85831 — 1 m, 3.5 mm male to female, gold-plated contacts, AWG 28, black

DELOCK 85831 is a 1 m audio extension cable with a 3.5 mm male plug to 3.5 mm female jack and gold-plated contacts. The cable uses 28 AWG conductors and a black TPU jacket. A screw-on adapter is included that converts the 3.5 mm male connector to a 6.35 mm interface, allowing use with devices that have either 3.5 mm or 6.35 mm stereo jacks. The cable is coiled to reduce storage space and the TPU outer material provides flexibility and mechanical resilience for regular handling.

Advantages

The gold-plated contacts improve conductivity and help maintain a stable audio signal. 28 AWG wiring provides a balance between flexibility and signal integrity for short extensions. The screw-on adapter enables compatibility with 6.35 mm jacks without requiring a separate adapter, and the coiled design reduces tangling and occupies less space when stored. The TPU jacket increases flexibility and abrasion resistance compared with standard PVC jackets.

Suitable for

• Extending headphone connections to smartphones, tablets and portable players
• Connecting speakers or line-level audio devices to PCs and audio equipment
• Temporary or mobile setups in home studios and rehearsal spaces
• Car stereo systems where a short reliable extension is needed

Key specifications

• Length: 1 m (coiled cable)
• Connector: 3.5 mm male to 3.5 mm female
• Adapter: screw-on 6.35 mm compatible adapter for the 3.5 mm male plug
• Contacts: gold-plated
• Conductor size: 28 AWG
• Cable jacket material: TPU (black)
• Cable type: stereo audio extension (coiled)

How to use

Insert the 3.5 mm male plug into the source device or existing cable and connect headphones, speakers or other audio equipment to the 3.5 mm female jack. If a device requires a 6.35 mm connection, screw the included adapter onto the 3.5 mm male plug before connecting. Route the coiled cable to avoid excessive stretching; the coil provides a compact profile while allowing necessary extension for typical listening distances.

Recommendations

For best signal quality, keep the extension length short and avoid routing the cable near high-power cables or strong electromagnetic sources. Do not overstretch the coiled section; allow some slack to reduce mechanical stress on connectors. Clean the gold-plated contacts periodically with a dry, lint-free cloth to maintain reliable contact.
