40 mm Replacement Headphone Speaker Driver for AKG Headphones

One side of a favourite pair goes silent while the headphones are otherwise fine, so a replacement driver costs less than a new set. This 40 mm full-range unit is a 32 OHM speaker with a titanium film diaphragm, offered for many AKG models from K480 to Y500. It suits anyone repairing their own pair.

A Driver That Restores One Silent Side

✅ A repair, not a new pair When one side dies, the new driver goes into the existing cup and the headband, cable and pads stay as they are.

✅ Polarity marked for soldering A red dot marks the positive terminal, so you can match the driver to the wires before you solder.

✅ Useful for DIY builds The same unit is offered for home-built headphone projects as well as for bringing an existing pair back.

✅ Metal frame, titanium film The maker gives a metal body and a titanium film diaphragm, the two parts that define how this driver is built.

✅ Full range from one driver The unit is given for the whole frequency band, so one driver covers bass and voices without a second element.

The job itself is short. Open the cup, desolder the old driver, note which wire went to the red-dot side, then fit the new unit and close up. The 40 mm figure is the measurement to check first, because a driver of another diameter will not sit in the same recess.

Quantity is the question to settle before ordering. The pack is described only as a package, with no count given, so decide whether you are renewing one side or both and order the number of units you need rather than assuming a pair arrives.

On branding, the maker states: 'The product is made by POYATU. It does not bear any trademarks that are owned by the original headphone companys, and the seller is not affiliated with the headphone company in any way.' This is a spare part, not a headphone built by AKG.

The figures belong to the driver, not to the finished headphone: 32 OHM, a rated power of 0.5 W, distortion of 2 % and a sensitivity of 111 dB/W. What the assembled pair sounds like depends on the cup, the pads and the cable around it.
