Boxwave

Boxwave 3.5 mm TRRS audio adapter 8-piece set

SKU CH-C0B5-91430

Eight 3.5 mm TRRS adapters convert balanced audio jacks to screw-terminal blocks for custom wiring without soldering

  • TypeAdapters
  • Eight-piece set gives four male and four female TRRS connectors for balanced audio wiring
  • Gold-plated copper contacts on each adapter maximise signal transfer and resist corrosion
  • Four-conductor TRRS design carries three signals plus ground for microphone and stereo applications
  • Screw-terminal blocks let you attach stranded or solid-core wire without soldering
  • Black moulded plastic housings protect the terminals in CCTV camera and earphone installations

What is in the box

This set contains eight TRRS audio adapters, split evenly between four male and four female connectors. Each unit converts a 3.5 mm jack to a four-screw terminal block for custom wiring. The adapters arrive organised in a plastic storage box.

How it holds up under repeated use

Gold-plated copper contacts maintain low resistance across many connect and disconnect cycles. The screw-terminal design removes the need for soldering, so joints stay mechanically secure without thermal stress on the conductors. Moulded plastic bodies resist cracking during routine handling.

The spec that decides fit

These adapters use a four-conductor TRRS layout with three signal paths plus ground. They will not work with standard three-conductor TRS plugs that carry only stereo audio. Verify your device requires TRRS before ordering.

Questions about this item

How much heat does the adapter generate when used continuously?

The passive copper and gold-plated contacts produce no measurable heat during normal audio signal use.

What tools or cables do I need to connect wires to the screw terminals?

A small screwdriver and stranded or solid-core wire are all that is required; no soldering equipment is needed.

Will these TRRS connectors work with older stereo 3.5 mm plugs that have only three conductors?

They accept four-conductor TRRS plugs; a three-conductor TS or TRS plug will connect but the fourth contact will remain unused.
