What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Unmatched virtual surround sound and immersive 3D audio from a single bar creates a cinematic experience without extra speakers
  • Excellent music performance with balanced drivers, clean highs, and tight, impactful bass
  • Supports a wide range of audio formats, including Dolby Atmos, DTS:X, DSD, FLAC, ALAC, and Sony's 360 Reality Audio
  • Thirteen drivers fully submerge the listener in the action, and the large drivers gives the bar a physical advantage over smaller speakers used in virtually every other soundbar
  • Updated software and app provide a simple setup and stable operation

Product Considerations

  • Bass performance is disappointing, especially on stereo content
  • Large and heavy design may be difficult to fit into some home theater setups
  • Lacks HDMI 2.1 support, which may be a drawback for gamers seeking high frame rates on the latest consoles
  • Virtual surround sound is good, but cannot quite match the clarity and positioning of a real multi-speaker system, especially for sounds behind the listening position
  • During testing, the soundbar got hot and smelled like burning plastic after only 10 minutes of operation

Comparisons (according to reviewers)

  • Vs Sonos Arc: Reproduces a more extended low-bass
  • Vs Sennheiser AMBEO Soundbar Plus: Is a bigger setup with a lot more rumble in the bass
  • Vs Sonos Beam (Gen 2): Reproduces a more extended low-bass and has a better Atmos performance
  • Vs Sony HT-A7000: Ambeo system is a marvel to behold, even as offerings like the Sony HT-A7000 get closer than ever to its virtual sorcery

Takeaway: The Sennheiser Ambeo Max is a premium soundbar that delivers an incredible virtual surround sound experience from a single unit. It is ideal for those who want a high-end, immersive audio experience without the complexity of a multi-speaker setup.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

HD-559  

  • Positioning: Entry-level design focused on affordability and everyday listening needs.  
  • Description: Offers clear sound and comfortable design with a straightforward acoustic setup suitable for small rooms and casual music enjoyment. Compared to the HD-560S and HD-660S2, its basic performance and limited feature set make it a better fit for buyers with lower budgets and simple functionality needs.

HD-560S  

  • Positioning: Mid-tier model balancing cost and improved technical performance.  
  • Description: Delivers enhanced clarity and precision with a refined tuning approach that benefits home or studio use. When compared with the HD-559 and HD-660S2, it provides better sound detail while remaining accessible for buyers seeking moderate cost and practical functionality.

HD-660S2  

  • Positioning: Mid to high-level design crafted for a richer and fuller sound experience.  
  • Description: Offers a warmer sound signature with improved bass impact and a wider soundstage. Relative to the HD-560S and HD-800S, its technical enhancements and superior build quality justify the higher investment for users aiming for more refined performance without reaching the premium flagship tier.

HD-800 S  

  • Positioning: High-end open-back design intended for detailed, analytical listening applications.  
  • Description: Provides natural, transparent sound with a wide soundstage and precise imaging that benefits critical listening in controlled environments. Compared to the HD-660S2 and HD-820, it emphasizes technical accuracy and spatial detail.

HD-820  

  • Positioning: Premium closed-back design engineered for reference-class listening in isolated environments.  
  • Description: Features a unique closed-back design that merges open headphone sound characteristics with enhanced bass warmth and improved isolation, suited for quiet and nearfield environments. In comparison with the HD-800 S, it prioritizes sound isolation and versatility over the expansive open-air presentation.

Our take on the brand

Sennheiser pioneered the world's first open-back headphones with the HD 414 in 1968, which became the bestselling full-size headphone of all time, and later developed the HD 25, evolving from 1980s broadcast use to become the industry standard in DJ booths worldwide. The brand is known for unique engineering approaches, such as integrating high-voltage amplifiers directly into earcups with Carrara marble chassis in the HE 1, developing proprietary ring-radiator transducers and absorber technology to eliminate resonances, and creating the long-running MD 421 microphone that has remained in production since 1960.
