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.

Product Strengths
- Exquisite build quality with premium materials, like anodized aluminum, memory foam, lambskin leather, and high-quality polymer
- Very comfortable, generously padded with memory foam wrapped in lambskin, and the headband distributes pressure evenly
- Long battery life, up to 35 hours with ANC on and 40 hours with ANC off
- Sound quality is rich, refined, spacious, balanced, and impressively detailed
- Good voice pickup and decent noise suppression in moderately noisy environments
- Connectivity options are available
Product Considerations
- Round ear pads may pull down on ear cartilage and rest on ear lobes
- The HX can only be laid down flat, they are not fully collapsible
- ANC is good, but not quite at the level of industry leaders
- Touch panel is awkward to use, and touches are often not registered properly
Comparisons (according to reviewers)
- Vs Sony 1000XM4/XM5 and Bose 700, ANC on the HX is not quite at the level of these industry leaders
- Vs the H95, the HX are more sensible, and noticeably cheaper
- Vs the Sony XM3, the HX looks far more refined
- Vs the Apple AirPods Max, the HX has up to 15 hours of additional battery life, and are also 100g lighter
- Vs the Bowers & Wilkins PX7, the HX brings a slightly higher level of refinement, showcasing detail and nuances that are missed
Takeaway: The Beoplay HX are beautifully made headphones that deliver excellent sound quality and are highly comfortable. If the user values aesthetics as much as audio and is willing to pay a premium for quality, then the HX is worth consideration.

/
Released
2023
The WH950NB headphones are equipped with intelligent, active noise cancellation algorithms that remove surrounding noise. There are two active noise cancellation mode selections that meet everyone's needs. Furthermore, users can choose between ambient sound or wind reduction in different scenarios to create their ideal environment.
Edifier, a hifi audio brand, horn-loaded ribbon tweeters to affordable active monitors through their Airpulse series. The brand achieved the first Hi-Res Audio certified true wireless earbuds with their NeoBuds Pro and in 2010 became China's first publicly listed audio speaker company.
Expand Details
Our Summary
Comparisons (according to reviewers)
- ANC does not compete with Sony or Bose, even in the same price category, let alone their higher-end stuff.
- The Sennheiser HD 450BT and the Urbanista Los Angeles offer better ANC or a unique solar charging design, respectively, for a small price increase.
- More comfortable than the Skullcandy Crusher ANC 2 and Apple AirPods Max thanks to plush padding.
- The Edifier WH950NB hybrid ANC is well implemented, making it a legitimate reason to consider, even outside of the big price savings, as the Stax SPIRIT S3 does not feature any noise cancellation.
Takeaway: The Edifier WH950NB is a comfortable and feature-rich headphone that offers good noise cancellation and balanced sound, making it a solid choice for commuters or anyone seeking an immersive listening experience. With its long battery life and customizable app, these headphones are a great value for the price.

Released
2022
The MOMENTUM 4 Wireless combines audiophile-inspired sound, Adaptive Noise Cancellation, 60-hour battery life, and supreme comfort in a fold-flat wireless headphone.
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.
Expand Details
Our Summary
Product Strengths
- Sound quality is excellent; multiple reviewers describe sound quality as impressive right out of the box (no EQ)
- Good battery life, lasting over 55 hours with ANC on
- Connectivity options include wired listening over USB-C and the standard TRS jack
Product Considerations
- ANC performance is not as strong as competitors, reducing outside noise and loudness by about 76% across all the samples that were taken, while the Apple AirPods Max can achieve something like 88%
- Touch controls can be too sensitive and can be triggered by mistake
- There are some unexpected rough edges; sometimes the touch controls just do not work when first starting the headphones
Comparisons (according to reviewers)
- Vs Sony XM5: The Sennheiser Momentum 4 outperforms the Sony WH-1000XM5 in terms of sound quality
- Vs Apple AirPods Max: Transparency mode is not as good
- Vs Sennheiser Momentum 3: The Momentum 4 provides improvements in vocal clarity compared to the Momentum 3
- Vs Bose QC45: The Bose QuietComfort 45 have better ANC
Takeaway: The Sennheiser Momentum 4 Wireless headphones offer flagship sound, comfort, and long battery life. They could be a good choice for anyone who values sound quality and extended battery life.
