Sennheiser AMBEO Soundbar Plus vs Samsung HW-QS90H Soundbar

The Sennheiser AMBEO Soundbar Plus is the stronger pick for movie fans who want true 7.1.4 virtualization, DTS:X and MPEG-H support, and the widest connectivity, including RCA, optical, Ethernet and AirPlay 2. The Samsung HW-QS90H is a wider all-in-one bar with 13 drivers, four woofers and 580 W, and it adds a display and voice control. The Sennheiser carries more ratings and a proven track record; the Samsung's higher score comes from a much smaller pool of owners. Build on both is plastic-bodied and wall-mountable, and neither is water-resistant.

  • Choose the Sennheiser AMBEO Soundbar Plus if you want the most complete format support and connections, with 7.1.4 virtualization and DTS:X from a single bar.
  • Choose the Samsung HW-QS90H if you want a wider bar with more drivers, four woofers and an on-screen display, and you mostly watch Dolby Atmos content.

What reviewers say

Sennheiser AMBEO Soundbar Plus

  • 4.5 / 5308 ratings

Rated 4.5 out of 5 from 308 ratings, the AMBEO Soundbar Plus is well received for its room-filling virtual surround and strong built-in bass. Owners still flag the price and its size.

What people mention
  • Surround effectMixedListeners find the virtual 7.1.4 staging impressive but less precise than physical speakers.
  • BassPraisedThe dual built-in subwoofers are said to deliver deep bass without a separate sub.
  • CalibrationPraisedAutomated self-calibration is described as quick and effective at adapting to the room.
  • PriceCriticisedReviewers call it expensive for a single soundbar.

Samsung HW-QS90H Soundbar

  • 4.8 / 540 ratings

Questions and answers

Which is better for movies with DTS soundtracks?
The Sennheiser. It decodes DTS:X and MPEG-H as well as Dolby Atmos, while the Samsung lists Dolby Atmos only.
Which has more bass without a separate subwoofer?
The Samsung on paper, with four woofers and 580 W against the Sennheiser's dual 4-inch subwoofers and 400 W. The Sennheiser reaches down to 38Hz and self-calibrates, so the gap is smaller in a real room.
Which is easier to fit under a TV?
The Sennheiser. The Samsung is 49 inches wide, so measure your stand and TV first.
Is the Samsung worth stepping up to over the Sennheiser?
Only if width, driver count and a display matter more to you than format support and inputs. The Sennheiser covers more codecs and connections.
Which lasts longer?
Neither maker publishes a lifespan figure. The Sennheiser has far more owner ratings behind its score, which gives a better read on long-term satisfaction.
Can either be wall-mounted?
Yes. Both are listed as wall-mountable, and the Samsung also sits flat on a table.
