Latest release note

Release date

March 11, 2026

Release version

2.54.0

New Features:

  • Soft start – Speak2 75 will now operate at a very low battery level.
    • When operating at a very low battery level, maximum volume will be limited. This also applies if linked to another Speak2 75, and one unit is at a very low battery level; maximum volume will be limited on both units.
    • If trying to increase the volume at a very low battery level, the battery indicator will illuminate in red.
  • Deep sleep mode for new units arriving with this firmware out of the box. To activate the unit, simply connect it via the USB cable.
    • The unit only needs to be activated the first time out of the box.
    • This helps prevent units from potentially being unboxed in a deeply discharged state.

Updated:

  • Faster charging at a very low battery level.

Fixed:

  • Could be stuck in Standby mode instead of Sleep mode.
