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

Product Strengths

  • Excellent sound quality, described as articulate, natural, and impressive with great instrument separation
  • Support for high-quality codecs like aptX Lossless and Snapdragon Sound provide near lossless audio and high-resolution capabilities

Product Considerations

  • Some reviewers found the default sound tuning to be bassy and muffled, needing EQ adjustment
  • The Sennheiser Smart Control app's EQ is considered basic and limiting
  • The case is considered larger than competitors
  • Some found the ear tips did not seal as easily as other earbuds
  • Some reviewers experienced a hissing sound in transparency mode

Comparisons (according to reviewers)

  • Vs. AirPods Pro 2: AirPods Pro 2 sounds better out of the box, has better ANC and transparency, and better ecosystem benefits for iPhone users

Takeaway: The Momentum True Wireless could be a good buy for those wanting earbuds that will last for years. With the right settings, they sound great and come with future-ready features.

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.

Our Summary

Product Strengths

  • Excellent sound quality with depth, great soundstage, and crisp, clean elements
  • Active noise cancellation is a useful addition and blocks out rumbling and background chatter
  • The earbuds themselves are smaller compared to the previous version
  • Touch controls are responsive and easier to use than the old version, and customizable

Product Considerations

  • Continuous battery life with ANC on is quite short at around 4 hours
  • The case is not the smallest and can create a bulge in your pocket
  • Microphone sounds muffled
  • These do not support multi-connect, meaning that these cannot connect to a phone and a tablet simultaneously

Comparisons (according to reviewers)

  • Momentum 2's do not support multi-connect like the Jabra Elite 75T
  • AirPods Pro's transparent hearing quality is better than Momentum 2's
  • Sony's noise-cancelling has an edge over the Momentum True Wireless 2
  • Galaxy Buds Plus have great clarity, but the bass isn't as good as the Momentum 2's
  • The Momentum 2's sound better than AirPods
  • Momentum 2 is more comfortable and nicer to use, battery life is better, and noise-cancelling is included

Takeaway: The Momentum True Wireless 2 earbuds offer respectable noise cancelation, sound good, and are sweat-resistant. These could be worth buying if sound is the main priority.

Expand Details

Our Summary

Product Strengths

  • Premium design and build quality, using materials like aluminum and glass for a luxurious feel
  • Sound quality is generally praised as excellent, detailed, and balanced, especially after equalization
  • Comfortable and secure fit, particularly for those with smaller ear canals
  • App provides an intuitive EQ interface with customizable presets

Product Considerations

  • Active noise cancellation (ANC), while solid, is not considered the best on the market compared to brands like Sony or Bose
  • Some reviewers experienced connectivity issues, including problems with multipoint pairing and occasional signal dropouts
  • Battery life is respectable but not outstanding, with some reviewers noting shorter-than-advertised playback times
  • Responsiveness of the touch controls is sometimes too sensitive, leading to accidental pausing or track skipping
  • Some users have found the default sound profile (Optimal) to be somewhat flat or boring, requiring EQ adjustments

Comparisons (according to reviewers)

  • Compared to the Apple AirPods Pro, the EX has more clarity, better soundstage and separation, but tonal balance may be preferable on the Airpods Pro
  • Compared to the Sennheiser Momentum True Wireless 3, the Beoplay EX offers a more balanced and detailed presentation with a more luxurious build
  • Compared to the Devialet Gemini II, the Gemini II offers a more neutral sound signature with advanced ANC capabilities, but Beoplay EX offers a more balanced and detailed presentation with a more luxurious build

Takeaway: The Beoplay EX offers a luxurious experience with refined sound and a stylish design. It's a good choice for those who prioritize sound quality and aesthetics, and value a premium feel.

HIFIMAN
Svanar Wireless
499
/
Released
2023
SVANAR Wireless — Ultimate Personal Audio in True Wireless Form.
Check Amazon
HIFIMAN is a hifi brand known for its planar magnetic headphones that use extremely thin diaphragms and acoustically transparent "Stealth Magnets" to reduce sound distortion. The company pioneered high-resolution portable audio players and creates electrostatic headphones that bring high-end sound quality to more accessible price points, as well as widely renowned flagship models such as the Susvara.
Expand Details

Our Summary

Product Strengths

  • Excellent sound quality, potentially challenging cabled IEMs, with a dynamic and holographic rendering and beautiful mids and airy treble.
  • Effective ANC, making it suitable for reducing ambient noise, even in noisy environments, with up to 35dB of noise attenuation.
  • Good build quality, with the IEMs made of lightweight metal and Kevlar, and a sturdy charging case.
  • Good bass performance, with texture and extension, punchy, without overpowering, and a powerful but tight impact.
  • Wide soundstage, creating a spacious and immersive listening experience.

Product Considerations

  • Connectivity issues with LDAC, especially outdoors or in areas with interference, leading to intermittent signal drops.
  • Transparency mode might generate turbulence in windy conditions due to microphone placement.
  • Limited codecs available, with no aptX support.
  • Physical size of the charging case is large and might not be pocket-friendly.
  • Included eartips may not be suitable for all ear sizes, with a shorter nozzle affecting fit for some users.

Comparisons (according to reviewers)

  • Vs Final ZE8000: Svanar Wireless offers a more W-shaped and punchy signature, greater upper mids gain, more precise imaging, and a vaster sound layering capability, while the ZE8000 sound more neutral to L shape, warmer, and have more sub bass boost and warmth.
  • Vs Noble FoKus Mystique: Svanar Wireless has some emphasis in the bass, but not as much, has stronger overall imaging performance—providing a wider soundstage and the best balance between the separation and cohesion in the imaging.
  • Vs HIFIMAN Svanar (wired): Svanar Wireless soundstage is taller and wider but not as deep, since clarity isn’t as sharp and clean, silence being more ”noisy”.
  • Vs Sony WF-1000XM4: The Svanar Wireless presents a much more detailed, natural and sophisticated kind of sound, while Sony has bloated bass, that overwhelms everything else.
  • Vs Apple AirPods Pro: The Svanar Wireless generally outperforms the AirPods Pro in sound quality.

Takeaway: The Svanar Wireless is a solid choice for TWS lovers, with a top-tier sound quality, effective ANC, and its convenience and comfort. It is innovative, less bass-heavy tuning, and overall a solid proposal.

Our Summary

Product Strengths
