Casio WU-BT10 Wireless Bluetooth Audio & MIDI Adapter
Bottom line: The Casio WU-BT10 Wireless Bluetooth Audio & MIDI Adapter ($94.99 on Amazon as of 2026-10-06): Bi-directional Bluetooth MIDI between CDP-S/Privia PX-S boards and phones, tablets or DAWs; main trade-off: locked to select Casiotone, CDP-S and Privia PX-S models, not universal Bluetooth MIDI.

Pros & Cons
Pros
- ✓ Bi-directional Bluetooth MIDI between CDP-S/Privia PX-S boards and phones, tablets or DAWs
- ✓ Streams Bluetooth audio through the piano's built-in speakers or connected headphones
- ✓ Drops the USB-to-host cable run for wireless lesson-app and DAW sessions
- ✓ Tiny 0.24 lb adapter travels in a gig-bag pocket with no external power brick
- ✓ First-party Casio part, so fit and firmware handshake are matched to the listed models
Cons
- ✗ Locked to select Casiotone, CDP-S and Privia PX-S models, not universal Bluetooth MIDI
- ✗ Bluetooth audio and MIDI both add latency versus a wired USB-to-host connection
- ✗ Occupies the piano's dedicated adapter port, blocking other accessories in that slot
