2.5mm TRRS To 3.5mm Stereo Splitter Adapter – Headset & Mic Combo Cable (0.5m)

Need to connect an older phone or device with a 2.5mm port to your favorite 3.5mm headset?

This little adapter is what you need.

It has a 2.5mm TRRS (4-pole) plug on one end and splits out to two 3.5mm jacks—one for your headphones and one for your microphone.

It works with a bunch of brands like Alcatel, BlackBerry, and even Apple.

The cable is about 0.5 meters long, so it gives you a bit of reach.

It's a basic, no-frills adapter made of black plastic, but it does the job.

Weighs next to nothing at 20g.
