This 3-in-1 firmware is valid for
To run firmware upgrades with this 3-in-1 firmware you need to use SpeechControl version 4.3 (or later), SpeechMike SDK 4.3 (or later) or PRDM 4.3 (or later).
To guarantee the correct functionality you need to run firmware updates for all connected devices:
Improved Windows 10 compatibility: With the latest Windows 10 release, Microsoft has changed the USB audio interface. Due to that Windows 10 did no longer accept the reported default microphone level of the device during the first connection and the microphone level was set to zero (0). To overcome this issue we have adapted the firmware in order to guarantee that the correct microphone lecel is now reported to the USB host.
Controlling the playback sound
volume by the touch sensor of a SpeechMike Premium Air works properly now.
IMPROVEMENT | Changed Record LED behavior in Browser mode: The behavior of the Record LED has been changed in Browser Mode to be like in the other custom (keyboard) modes. The Record LED is now turned on/off depending on USB audio stream. In previous firmware versions the Record LED was dark during recording in Browser Mode. [SMPA-113]
FIX | SMPAir constantly sends "CTRL+Shift" after pairing with AirBridge: If the SMP Air docking is still connected to the PC via USB, the AirBridge is connected to the PC and the SMP Air is in Dragon for Windows Mode. Now when the SMP Air (in Dragon for Windows Mode) is paired with the Airbridge, F1 and F2 is pressed, the SMP Air will continuously send the key signals "CTRL+SHIFT". This issue is solved now.

FIX | SMPA does not transfer audio data after PC is turned off over night: In some cases the SpeechMike Premium Air did not transfer any audio data after PC startup if it was connected to the PC and the PC was turned off over night. This issue is solved now.[SMPA-115]
Improved Windows 10 compatibility: With the latest Windows 10 release, Microsoft has changed the USB audio interface. Due to that Windows 10 did no longer accept the reported default microphone level of the device during the first connection and the microphone level was set to zero (0). To overcome this issue we have adapted the firmware in order to guarantee that the correct microphone lecel is now reported to the USB host.
More reliable firmware upgrade process: We have learned that approx. 50% of all firmware upgrades were not initiated, because the device denied to upgrade the firmware for safety reasons. After re-evaluating all safety aspects, we were able to make the firmware upgrade process more reliable in that the device also allows a firmware upgrade in playback mode.
IMPROVEMENT | Changed Record LED behavior in Browser mode: The behavior of the Record LED has been changed in Browser
Mode to be like in the other custom (keyboard) modes. The Record LED is now
turned on/off depending on USB audio stream. In previous firmware versions the
Record LED was dark during recording in Browser Mode.

IMPROVEMENT | Optimized charging of the battery:
The charging cycle of the battery has been optimized in order to enable a longer
battery life. To do that we have disabled the boost charging mode which was only
avaliable when the charger was directly connected to the headset. Secondly we
have changed the charging threshold to reducing the number of required charging
cycles. [SO-107, SO-110]
FIX | SO does not transfer audio data after PC is turned off over night: In some cases the SpeechOne did not transfer any audio data after PC startup if it was connected to the PC and the PC was turned off over night. This issue is solved now. [SO-111]
