Product Strengths
- Secure fit is achieved via included ear tips and wings, suitable for any fitness routine
- Good battery life, lasting over 7 hours in tests
- Sound quality is good, with a frequency response that closely follows the headphone preference curve

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:
Select products
Select product comparisons
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.

- Fit might not be perfect for everyone, as the earbuds are slightly on the larger side.
- Touch controls can be sensitive, and may require getting used to.
Comparisons (according to reviewers)
- Vs AirPods Pro: Beoplay 11 has a bigger case.

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.
