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.

Reviews

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.

Reviews

Expand Details
Product Strengths
- Premium build quality with materials like lambskin leather, aluminum, and tempered glass, gives it a solid and luxurious feel
- Comfortable for extended wear, due to soft memory foam padding on earcups and headband, and a balanced headband
- Balanced sound signature with warm bass, clean mids, and well-defined treble, making it suitable for various music genres

- Comprehensive package includes various adapters for different connections, and a hard-shell carrying case for protection
Product Considerations
- The earcup size might be too small for some users, potentially affecting comfort and seal
- Some reviewers found the clamping force to be loose, which could be an issue for active use
- Audible hiss can be noticeable when ANC is activated
- The app lacks a customizable graphic EQ
- Ambient mode is subtle and might not let in as much surrounding sound as competing models
Comparisons (according to reviewers)
- Compared to the Sony WH-1000XM5, the Master & Dynamic MW75 delivers above-average ANC performance, but it is not class-leading
- Compared to the Bose QuietComfort 45, the Master & Dynamic MW75 has an audible ANC hiss
Takeaway: The Master & Dynamic MW75 are stylish and comfortable headphones that deliver excellent audio quality and decent noise cancellation. They are a great choice for those looking for a premium listening experience and appreciate high-quality materials.

Our Summary
Product Strengths
- Good value.
- Great transmission range and battery life.
- Touch controls work well.
- Comfortable for long listening sessions.
- Portable design.
Product Considerations:
- Doesn’t support aptX codec.
- Sounds better in cabled mode.
- Noticeable difference in sound quality compared to when using them with a wired connection.
- Latency makes Bluetooth unsuitable for monitoring when programming and recording in real-time with a DAW.
- Seemed a little harsh at times, with what seemed to be a pronounced bump around the 1-2kHz region, making these quite fatiguing to listen to for long periods at a moderate volume when cabled.
Comparisons (according to reviewers)
- The cabled version is less costly and is a better bet for music production, versus the AKG K361.
- Mentioned as an alternative option, versus the Audio-Technica ATH-M50xBT.
Takeaway: The K361-BT is an intriguing wireless headphone, and the draw of wireless listening is a big plus if convenience is a concern.

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.
