Audio split for TRRS headsets

This Defendwe cable separates a single 3.5mm TRRS combo port into dedicated headphone and microphone jacks. It lets you connect legacy analogue headsets or external microphones to modern laptops, tablets or smartphones that only provide a four-pole socket. The 20cm length keeps the adapter tidy in a laptop bag or pocket. Gold-plated contacts and a TPE jacket maintain signal integrity for clear voice and stereo playback.

Replaces proprietary combo-port dongles

Many ultra-portable devices omit separate audio sockets, forcing users to rely on USB audio adapters or Bluetooth headsets. This splitter restores wired analogue connectivity without driver installation or battery drain. The upgrade is worthwhile when you prefer a trusted wired headset, need lower latency for calls or recording, or want to avoid the bulk and cost of a USB sound device.

Fits any 4-pole 3.5mm jack

Plug the male TRRS end into the device and attach your headphone and microphone plugs to the two female ports. The cable works with smartphones, tablets, laptops and portable recorders that follow the CTIA pinout. It frees you from carrying a separate USB audio interface and leaves the device’s USB-C or Lightning port free for charging or data.

Questions about this item

Will the 20 cm cable reach from my laptop's 3.5 mm combo jack to headphones on the desk?

The 20 cm length is intended for close-range use such as a laptop bag setup; measure your routing path before relying on it for longer runs.

Does the TRRS male plug insert fully into a recessed 3.5 mm port on a tablet case?

The gold-plated 3.5 mm male connector has a standard barrel length; very deep recesses or thick cases may prevent full insertion.

Will the gold-plated contacts on the 3.5 mm jacks need cleaning over time?

Gold resists oxidation, so routine cleaning is not required; occasional dry contact cleaner can restore conductivity if static or crackling appears.
