Product Strengths

  • Premium design and build quality with luxurious materials like aluminum, Kevlar, and sapphire glass

  • Support for advanced Bluetooth codecs like aptX Lossless and Bluetooth 5.4 for high-quality audio transmission

  • Relatively expensive compared to other true wireless earbuds
  • Larger size and heavier than many competing earbuds, potentially impacting comfort during workouts
  • Physical button controls feel outdated compared to touch controls on competitors

Comparisons (according to reviewers)

  • Compared to the Sony WF-1000XM5, the MW09 has better build quality, but the Sony has better noise cancellation and a more enjoyable default sound signature
  • Compared to the Bose QuietComfort Ultra Earbuds, Bose has superior noise cancellation
  • The MW09 is a noticeable upgrade over the MW08, with built-in EQ, longer battery life, improved durability, and better noise canceling
  • Compared to the Apple AirPods Pro 2, the MW09 has much better audio quality, though the MW09 is not ideal for phone calls

Takeaway: The MW09 earbuds are beautifully crafted with high-end materials and offer excellent battery life, making them a stylish and practical choice for enjoying music. With customizable sound and the latest Bluetooth technology, these earbuds provide a premium listening experience.

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:

  • Master & Dynamic products are distinguished by their use of premium materials like aluminum, lambskin leather, and tempered glass, resulting in a luxurious and durable design aesthetic.
  • The brand consistently delivers a "signature rich, warm sound" with a punchy bass response, often utilizing custom-designed beryllium drivers, which emphasizes musicality.

MG20 Wireless Gaming Headphones

  • Positioning: Budget-friendly wireless headphones designed specifically for gaming.
  • Description: Delivers clear sound and low latency that suits fast-paced gameplay, with a focus on comfort during long sessions. Compared to the MH40 and MW75 series, it offers fewer advanced noise cancellation and processing techniques, making it ideal for users on a tighter budget and who play in small spaces.

ME05

  • Positioning: Entry-level model aimed at portability and everyday use.
  • Description: Features a compact design with reliable wireless connectivity and straightforward controls that support casual listening. While it lacks the specialized tuning of the gaming MG20 and the active noise cancellation of the MW75 products, it may suit users with moderate budgets and daily portability needs.

MH40 Wireless Over Ear Headphones V2

  • Positioning: Mid-range wireless headphones focused on everyday over-ear listening comfort.
  • Description: Delivers balanced sound with improved battery life and a comfortable fit that enhances everyday use. Compared to the MG20 and entry-level ME05, it steps up on audio quality without adopting the premium noise cancellation and processing features found in the MW75 models.

MW75 Active Noise Cancelling Wireless Headphones

  • Positioning: High-end headphones featuring advanced active noise cancellation for immersive listening.
  • Description: Combines effective noise cancelling with high-fidelity sound quality, offering a refined listening experience in various settings. While it provides a clear upgrade in noise reduction over the MH40 and MG20, it is outclassed in specialized processing by the Neuro variant.

MW75 Neuro

  • Positioning: Premium flagship enhanced with innovative sensor technology for adaptive sound processing.
  • Description: Uses smart sensor features with active noise cancellation to adapt audio performance on the fly, offering a tailored experience in larger or noisier environments. Relative to the standard MW75, MH40, and MG20, it delivers more nuanced audio performance and additional functionality.

Product Strengths

  • Excellent passive noise isolation, better than many headphones with ANC enabled, creating a quiet noise floor.
  • Good build quality with quality materials like anodized aluminum, Alcantara headband, and protein leather pads.
  • 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.

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.
