What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

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:

  • Fostex integrates traditional Japanese artistry, such as Urushi lacquering and Aizome dyeing, into the design of their headphone housings, amplified by the acoustic properties of materials like Japanese cherry birch and maple wood.
  • They leverage their "Biodyna" driver technology, optimized with high magnetic flux densities (often using neodymium magnets), enabling detailed, dynamic, and low-distortion sound.
  • Their headphones are designed to be easily driven by a wide range of devices, often featuring a low impedance (25-32 ohms) and high sensitivity, increasing versatility and convenience for users.

TH616

  • Position: The entry-level unit offering basic amplification and straightforward control.
  • Description: Offers a simple design with clear controls suited for small room setups and limited connectivity, making it a budget-friendly option. Compared to the other models, it has a more basic feature set and lower output capabilities for users who do not require advanced performance or multiple functions.

TH808

  • Position: A compact mid-range option focused on balanced performance.
  • Description: Features a clean signal path and improved circuitry that supports better dynamic range and connectivity compared to entry-level models. Relative to the TH616, it delivers enhanced performance while maintaining a moderate price.

TH900MK2

  • Position: A mid-range model with advanced digital control and refined tuning.
  • Description: Incorporates digital tuning and smarter circuitry to boost clarity and responsiveness, making it well suited for varied room sizes and sonic goals. When compared with the TH616 and TH808, it provides a noticeable upgrade in audio detail and connectivity.

TH1100RP

  • Position: A high-end integrated unit designed for higher resolution performance.
  • Description: Offers robust processing and precise digital-to-analog conversion to deliver clean and powerful output for users with higher technical requirements. In contrast to the mid-range TH900MK2, it provides more detailed signal processing and expanded functionality.

T60RPMK2

  • Position: A flagship model that brings premium control and complete feature integration.
  • Description: Delivers groundbreaking performance with advanced components and a design focused on full connectivity and high-end sonic control. Compared to the lower-end models like the TH616 and TH808, it provides superior build quality and extensive functionality.

Product Strengths

  • Crafted with premium black walnut wood, offering a unique and aesthetically pleasing design, and each headphone is unique due to the natural grain of the wood.
  • A 50mm neodymium magnetic driver and a BIODYNA diaphragm made of biocellulose fiber contribute to detailed and accurate sound reproduction, wide dynamic range, and minimal distortion.
  • Lightweight and comfortable for extended listening sessions, due to premium vegan leather pads and aluminum mechanical parts.
  • Many different layers are revealed in the stereo field for great dimension, but the soundstage won’t extend too far outward, providing the listener a more intimate space for the tracks to operate in.

Product Considerations

  • The stock cable is long, heavy, and stiff, and it uses Fostex's proprietary connectors, which some reviewers dislike and recommend replacing.
  • Some reviewers found the high frequencies to be too bright, which could be fatiguing for some listeners over extended periods.
  • The low end is considered moderate and may lack the visceral feeling or rumble desired by bass enthusiasts.
  • The carrying pouch appears very bland and like an afterthought during development.

Comparisons (according to reviewers)

  • Compared to the Fostex TH909, the TH616 features 50mm drivers with Fostex’s own Biodyna cones, as used in the high-end model.
  • Compared to the beyerdynamic DT-990 Pro, the TH616 is V-shaped like the DT-990 Pro, a headphone infamous for its sonic faults.

Takeaway: The Fostex TH616 is a beautifully crafted headphone with great clarity and detail, offering an engaging listening experience. Pairing with a tube amplifier can enhance the sound by smoothing out the treble and expanding the soundstage.

  • Guitar melodies are presented in a detailed and finely resolved manner, even better than the AKG K702 Studio in terms of treble reproduction

Released
2024
The FiiO FT1 offers North American walnut / beech wood ear shells with natural solid wood construction, effectively reducing cavity resonance and minimizing standing waves. Each wooden ear shell features unique grain patterns.
Check Amazon
FiiO stands out for integrating unique features into portable audio devices, such as their BTR7 DAC/amplifier with its screen and wireless charging, and their KB3 mechanical keyboard with a built-in DAC/amp. The brand caters to audiophiles seeking personalization through products like their pioneering X7 music player with interchangeable amp modules and their compact R7 desktop system that combines streaming, DAC, and headphone amplification capabilities.
Expand Details

Our Summary

Product Strengths

  • Shockingly good for the money, a very well-tuned headphone for the price category
  • Good bass response that is fun, with lots of thumpiness and impact in the lower sub-bass regions, while maintaining a clean mid-bass region
  • Trouble response is fairly target-adherent with a chill character and not overly fatiguing
  • Comes with a banger accessories package providing two cables, a carry case, more than a lot of companies are coming out with
  • Delivers impressive sound quality across the board, backed by excellent build quality and a generous set of accessories

Product Considerations

  • The actual earpad area for the ear is not super great, and it will be felt a little bit on the ear, might be more on-ear than fully over-ear if you have really large ears
  • Sound staging is one area that could improve the most, because there is almost none, can sound almost claustrophobic, because everything is happening right here all the time
  • Mid-range is not all that exciting to listen to, vocals can be shouty or honk-type sound to certain vocalists
  • Build quality feels good for $150, but it would not pass the sniff test for $500, definitely feels like it's a budget device

Comparisons (according to reviewers)

  • The AKG K361 has advantages over the FiiO FT1, like sound staging
  • The FT1’s level of midrange fidelity is impressive, rivaling the best mid-fi headphones such as the Sennheiser HD6XX and the Sundara
  • It outshines most closed-back classics, including the Sony MDR-7506, AKG K361, and beyerdynamic DT700 Pro X
  • The smaller FiiO FT1 was enjoyed even more than the FiiO FT5, since it strikes the right balance between fun, warmth, and technicality, handling tough tracks with much more ease than anticipated

Takeaway: The FiiO FT1 is a surprisingly good closed-back headphone for the money and offers a well-tuned sound signature with good bass response. This headphone is priced at $150 and is surprisingly nice with some great terminations.

Sennheiser
HD 560S
279
/
Released
2020
With linear acoustics tailored to extended listening sessions and smooth, gratifying bass performance, the HD 560S was crafted for the analytical audio enthusiast.
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

  • The HD 560S delivers a flat sound profile that should suit most musical genres
  • Very comfortable, with a relatively lightweight design and plenty of plush padding
  • Soundstage is exemplary
  • Lightweight and provide a nimble feel
  • Excels in delivering both vocals and instruments with a remarkable level of clarity and precision

Product Considerations

  • Some users might find it a bit dull over time due to its conservative sound signature
  • Can be a bit intense at times in the lower treble
  • The plastic construction does not scream luxury
  • Some loss of texture in the mid-bass, with bass notes of different instruments often sounding the same

Comparisons (according to reviewers)

  • Vs AKG K702: 560S' sound is going to feel a bit closer, but it may not always be a good thing when trying to hear what is farther off in the distance, for gaming
  • Vs Sennheiser HD58X: The 560S is cleaner and more accurate sounding than the HD58X
  • Vs Sennheiser HD600: The 560S is more intimate and livelier sounding than the darker HD600
  • Vs HIFIMAN Sundara: Compared to the more expensive Hifiman Sundara, the 560S sounds like it lacks detail across the frequency spectrum, except in the sub bass region where the Sundara does not seem to dig as deep

Takeaway: The Sennheiser HD560S is a comfortable headphone with a well-balanced sound, making it a solid choice for both gamers and music enthusiasts looking for neutrality and clarity. It is a versatile headphone for various genres and applications.
