## Description

Tiny Versatile 2.5mm male to 3.5mm female Universal adapter, for attachment to headsets/devices with 2.5mm audio input , eg with Bose QuietComfort 25, Audio Technica headsets, etc With Tiny Versatile 2.5mm male to 3.5mm female Universal adapter, KOKKIA iAdapter Bluetooth aptX Receiver (not included) can be attached to a wide range of devices with 3.5mm or 2.5mm audio input, to i) provide Bluetooth Stereo Receiver capabilities or ii) to enhance existing standard Bluetooth devices with aptX quality. Firm attachment (no unwieldy dangling cord), tiny size, elegant design. Has lock/unlock feature for headsets that have matching lock/unlock design (eg Audio Technica). Very slim design to be able to fit in Bose QuietComfort 25 and many other headsets - no other design on the market is slimmer than this. Includes : 1 pc Tiny Versatile 2.5mm male to 3.5mm female Universal adapter

Review: Broke immmediately - Avoid - There is an outer casing on this that detached itself from the rest of the adapter as soon as I tried to remove it from my Audio Technica Headphones ATH-M40X. It is now stuck in the headphones. When I try to unlock it, there are some scratching sounds which I assume is the outer casing free-spinning but I am worried this could damage the headphones.
Review: I'm glad this adapter exists! The adapter works fine with the vmoda boompro mic and my Sennheiser headphones. It is a little difficult to push in all the way in but it will snap/click-in with a little pressure. Just be careful when you're pulling it out from the headphones because there is a little resistance.
