Boss released WAZA-AIR BASS system program Ver.1.31 in October 2025, according to the update history on its support page1. The update covers the bass version of the wearable spatial audio amplifier; the guitar version, the WAZA-AIR, received a Ver.1.31 update in the same month with the same gyro sensor change and a different app version requirement2.
Boss states that the update improves "the sense of stability of spatial audio positioning" through "enhanced tracking accuracy and responsiveness of the gyro sensor that detects head orientation"1. The page also notes that leaving the unit stationary for about 10 seconds after powering on "may improve sensing calibration precision, resulting in more stable spatial positioning"1.
Ver.1.31 adds compatibility with BOSS TONE STUDIO for WAZA-AIR BASS version 1.2.0 and later1. The equivalent WAZA-AIR update adds compatibility with BOSS TONE STUDIO for WAZA-AIR version 1.3.0 and later2.
"The sense of stability of spatial audio positioning has been improved through enhanced tracking accuracy and responsiveness of the gyro sensor that detects head orientation."
The update is installed from a Windows or Mac computer with a USB 2.0 or 3.0 port and the micro USB cable included with the unit. The process requires removing the right ear pad and the sponge over the SERVICE (USB) connector, connecting the unit to the computer, and copying the files WAZA-ABS.BIN and ROMINFO.TXT to the WAZA-AIR B drive. Boss says the update takes about 30 seconds once started1. The current version can be checked by holding the Up/Down buttons while turning the power on and reading the blink pattern of the bass wireless and Bluetooth indicators1.
The page lists earlier releases: Ver.1.30 in November 2022 added support for the FS-1-WL wireless foot switch, including patch switching, effect on/off and PEDAL WAH and FOOT VOLUME control from an EXP pedal, with assignment through the BOSS TONE STUDIO app1. Ver.1.21 in September 2021 improved behavior and BOSS TONE STUDIO connection stability1.
Boss lists no price for the system program download1.
