Denon just rolled out a major HEOS software update for the Denon Home 550 soundbar and Denon Home 150, Denon Home 250 and Denon Home 350 wireless speakers.
This update adds built-in Alexa voice assistance to the entire Denon Home range, as well as the ability to stream 5.1-channel surround sound wirelessly to the Denon Home 550 soundbar. Owners of the Denon Home 550 soundbar can now associate it with a pair of Denon Home 150 speakers or a Denon Home 250 or Denon Home 350 stereo speaker as wireless rear speakers to enjoy a fully immersive sound experience.

In addition, via this update, the Denon Home 550 soundbar benefits from upgraded DSP, which makes it possible to improve the bass response for a more impactful sound.
Finally, in addition to the new features provided by this update to the Denon Home range, all users of devices integrating HEOS multi-room technology can now enjoy a new look in the HEOS application with a more streamlined and intuitive interface.
