Confirmed ear pad compatibility XB Mount:

  • XB 500 ear pad (Sony)

  • XB 700 ear pad (Sony)

  • XB 1000 ear pad (Sony) due to its size it might cover the vents on vented PadMod

In our opinion the ported adapter option adds some low end to the sound.

In our opinion the non-ported adapter option widens the soundstage.

For guidelines regarding mounting and dismounting the adapter plate, watch our instructional video here.

We are including a set of longer screws for mounting the adapter plates. Use these if you find the stock screws too short.

The screws mount into plastic threads on the Stax earspeakers - Be careful not to use too much force.

Production time: 2-4 days.
