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:

  • Bose products prioritize unparalleled comfort, allowing for extended wear, a hallmark of the QuietComfort series.
  • They feature  effective and customizable active noise cancellation (ANC), with granular control to adapt to various environments, setting a benchmark in the industry.
  • The brand's companion app enables user customization through EQ settings and various listening modes like customizable active noise cancellation, spatial audio, and a transparency mode.

Ultra Open Earbuds

  • Positioning: The entry-level, open-design earbud focused on portability and environmental awareness.
  • Description: Uses an open-ear architecture that keeps ambient sound in play and suits active or outdoor use. Compared to other Bose products, these earbuds provide fewer advanced noise cancellation features than the QuietComfort models while emphasizing light weight and lower cost for casual listening.

QuietComfort Headphones (in-ear)

  • Positioning: A standard in-ear solution aimed at delivering balanced active noise cancellation and clear audio.
  • Description: Features active noise cancellation and crisp sound quality in a compact design that fits everyday use. When compared with the ultra in-ear and over-ear offerings, they offer a moderate noise cancellation level and soundstage that is suitable for small to medium rooms.

QuietComfort Ultra Earbuds

  • Positioning: A premium in-ear option built for enhanced noise cancellation and refined sound clarity.
  • Description: Incorporates more sophisticated noise cancellation and improved acoustic tuning for clearer audio in bustling urban environments. In contrast to the regular in-ear model, they bring advanced connectivity and battery performance, while differing from over-ear headphones by prioritizing portability and a less enclosed listening experience.

QuietComfort Acoustic Noise Cancelling Headphones

  • Positioning: A mainstream over-ear model delivering effective noise cancellation and a comfortable fit.
  • Description: Combines solid active noise cancellation and an immersive sound profile suited for extended listening in quieter settings. When held against the ultra over-ear series, they deliver balanced performance without the premium build and extra features, and they offer a more enveloping sound compared to the earbud lineup with reduced portability.

QuietComfort Ultra Headphones

  • Positioning: A high-end over-ear flagship distinguished by next-generation noise cancellation and advanced audio performance.
  • Description: Integrates enhanced noise cancellation and upgraded drivers that provide a more expansive soundstage designed for focused listening in larger spaces. Relative to the standard over-ear model, they offer superior build quality, connectivity, and refined audio tuning, making them distinct from both the basic in-ear and ultra in-ear options.

Our take on the brand

Bose pioneered commercial active noise reduction with the first aviation headset in 1989, leading to their consumer QuietComfort line. The company operates with a unique ownership structure where MIT holds majority non-voting shares (donated by founder Amar Bose in 2011), enabling long-term research priorities while remaining private and independent.

  • Supports a wide variety of Bluetooth codecs, including LDAC, AAC, aptX, aptX HD, and SBC, offering versatility in device compatibility.
  • Strong battery life, rated up to 80 hours without ANC and 60 hours with ANC, making it suitable for travel and extended use.
  • Powerful, textured, and nuanced bass is a standout feature.

Product Considerations

  • The included carrying case is bulky and may not be ideal for travel, taking up significant space in a bag.
  • Comfort is not great for everyone, with some users experiencing hotspots on the headband during extended use.
  • With ANC on, some users have noted the bass can become boomy with a reduction in sub bass.
  • Treble transparency mode is not as good as other models.
  • The headphone may clip the sound when ANC is on and the user hits bumpy roads or takes a harder step.

Comparisons (according to reviewers)

  • Vs Audeze Maxwell: The Apollo has a latency issue.
  • Vs Focal Bathys: The Apollo has a more engaging, punchy, and emotional sound, also it has more features and tech, but the Transparency mode of the Bathys is better.
  • Vs Apple AirPods Max: The Apollo offers superior sound quality with better clarity, speed, separation, and refined dynamics compared to the AirPods Max.

Takeaway: The Noble FoKus Apollo is a well-built wireless headphone with a strong battery life and great bass performance, making it an enjoyable choice for those who prioritize powerful sound and noise isolation. It offers a versatile listening experience with a range of connectivity options and a comfortable design.

ZE8000 MK2
349
/
Released
2023
ZE8000 MK2 further enhances the 「8K SOUND」 introduced by final for the first time as the initial model, which is an audio design capable of analyzing sound elements with extremely fine physical characteristics. Even tiny audio details can now be distinctly felt through the 8K SOUND. Simultaneously, through dual optimization of hardware and software, using "SN ratio" as a measure of the signal-to-noise ratio, the quality of song audio becomes clearer, and irrelevant noise is reduced, highlighting the details and subtle differences in musicality.
Check Amazon
Final is a hifi audio brand known for deep in-house manufacturing control by designing and building its own diaphragm-forming machines and assembly jigs, while engineering products like their D-series headphones for longevity through screw-fastened parts that enable user repairs and future upgrades.
Expand Details

Our Summary

Product Strengths

  • Upgraded 8K sound provides a crisper, cleaner, and more detailed sound, especially when enabling the 8K sound feature
  • Improved ANC performance compared to the previous generation ZE8000, with a 32% improvement in noise reduction
  • Enhanced comfort and a more secure fit due to the new 'Shield Fin' ear tips
  • The design minimizes contact between the ear and the plastic parts of the earphones, supposedly improving overall comfort
  • Wide soundstage with spatial imaging depth

Product Considerations

  • Battery life is not the best, offering only about 5 hours of playtime on a single charge
  • The case does not support wireless charging
  • Touch controls aren't intuitive
  • Some users may find the build quality of the case to be slightly lacking compared to the premium feel of the earphones themselves
  • The microphones on these earbuds do a pretty good job at focusing on speech and rejecting some of the noise going on around you, but the ANC and transparency modes are not quite top tier

Comparisons (according to reviewers)

  • Vs Bose QuietComfort Ultras: Dialogue and landscapers mowing lawns aren't eliminated as effectively
  • Vs Sony WF-1000XM5: ANC does not reduce noise as drastically, but the characteristic ‘whoosh’ sound was much more subtle and effective in translating music

Takeaway: The ZE8000 MK2 offers a noticeable step up in sound quality with the upgraded 8K sound, making music feel very large, showcasing a level of scale rarely found on true wireless earbuds. If you want possibly the best sounding wireless earbuds on the market, these are worth at least giving a shot.

2020
Leading audio technology and innovation with improved ergonomics designed for full day wearing and refined touch controls for a more personalised experience.
Check Amazon
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

  • 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.
