# technics-az100: a Windows client for EAH-AZ100 earbud controls

> technics-az100 reimplements control of Technics EAH-AZ100 earbuds on Windows through the Airoha RACE Bluetooth RFCOMM channel. A tray app and CLI set noise cancellation and ambient modes and read battery and codec status; a protocol log records frames and command IDs recovered from Android app analysis and Bluetooth captures.
