Replacement ST4 Remote USB Dongle: This is a replacement USB Bluetooth module that's compatible with the spectrum ST4. While many sub bluetooth dongles can connect, very few have the right specs for high speed (low latent) communication with the Sony PS4 Dualshock controller.
If you have lost or damaged the one that came with you spectrum, or you just want a backup, this is the one to buy. We test each of these to ensure compatibility before they go out the door.
