Keyboards in the Professional HYBRID and Professional HYBRID Type-S (silenced) series support both Bluetooth and USB (hence the "hybrid" moniker).
The Bluetooth version is 4.2 LE (Bluetooth 3.0 in previous models), and the USB port is Type C.

Up to four Bluetooth hosts can be paired, with fast switching between them or USB.
In Bluetooth mode, the keyboard is powered by two standard AA batteries. Alkaline batteries are estimated to last three months.
When a USB cable is used the keyboard does not draw power from batteries, and it is not able to charge batteries either. There is no USB hub.

The case designs is similar to the HHKB Professional BT, but with a shorter battery bump and equipped with an exposed Type-C port.
The logo has been moved to the top on all model variants, and there is an bi-colour LED for connection and battery status.

The keyboard supports simple key remapping in a [[Microsoft Windows]] or macOS program when connected via a USB cable. The mappings are stored on the keyboard and can be used in Bluetooth mode.
Three different layouts can be stored by using combinations of the first two DIP switches (off-off, on-off and off-on). The remaining four DIP switches configure mostly the modifier/function keys and override these keys in any user-created layout.

Twelve models (Normal/Type-S, White/Charcoal grey, Printed/Blank/Japanese) were introduced on December 10, 2019. There is no "JP" moniker for keyboards with Japanese layout.
