4-Pole TRRS 2.5mm to 3.5mm Adaptor

MSRP $12.95 ea inc GST

Converts between 2.5mm Female 4-Pole socket and 3.5mm Male 4-Pole Jack.

  • Slimline metal barrel
  • Gold plated contacts
  • Chrome finish


Our top-quality audio jack adapter is made almost entirely from metal, including the barrel and gold plated contacts. The only plastic parts are the separators between the poles, of which there are 4. If you’re not familiar with a 4-Pole (TRRS) audio jack, it has an extra channel which is typically used for a microphone – exactly like your iPhone headset with volume control.

Fully compatible with both stereo audio feeds and smartphone headsets. You’ll be well pleased when using this adapter with your iPhone, Skype headset or other basic stereo speakers. The premium build quality and materials make it extremely robust and hard wearing, and the chrome finish looks awesome.

Note: Not compatible with mono headsets for wired telephone systems.
