Not really an option.
These are both passive speakers so they need an amplifier to work, so you need speaker wires to go from the speakers to the amp (hence not wireless).
Depending on what you actually need you can make a wireless source to plug into the amplifier so that it receives BT or Wifi signal (but it's still plugged into the speakers)
That would be by connecting to the SA-5 SoundTouch amplifier. They are still wired to the amp, it just gives it access to wireless music sources (Spotify, tunein etc)
