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

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.

Comparisons (according to reviewers)
- The Arya is sharper, clearer, and better resolved than the HiFiMan Ananda, with a more open soundstage, but the Ananda has more bass grunt
- Both have large soundstages and effortless resolution, but the Arya has a more excited tuning while the Sennheiser HD800S is smoother

- Vs Sennheiser HD650: The Atrium overall tuning is very reminiscent of the Sennheiser HD 650, where it is still fairly neutral, but it tends towards a little bit of warmth
- Vs HIFIMAN HE1000 V2: The HE1000 V2 has a bigger soundstage, but the imaging and the separation handle spatial reproduction much better than the Atrium does

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Uses premium materials like carbon fiber, metal, sheep lambskin earpads, and zebra wood faceplates for a luxurious feel, with excellent build quality
- Has a mostly neutral sound signature, with lambskin pads bass response is very good with a tasteful emphasis placed on the sub-bass region, and a decent midrange

- A pad swapping system allows changes to sound characteristics, with lambskin pads and breathable fabric pads included
- Comes with a quarter-inch adapter and a 4-pin XLR adapter for use with portable or desktop devices
Product Considerations
- The stock cable is 3 meters long, which is too long for desktop use
- Headband adjustment can be a little stiff to move
- With leather pads, the highs can get slightly sharp
- There is a slight sharpness in the upper treble that might pose a problem for some listeners, using fabric pads can mitigate this
- Weight distribution could be better, there's not enough padding on the headband, and the clamp force is low, this distributes all the weight across the top of the head, which can be bothersome after 40-50 minutes
Comparisons (according to reviewers)
- Vs HiFiMan Susvara: Has a similar driver structure
- Vs HiFiMan HE1000 Unveiled: Is close in terms of technical performance like resolution, transient response, soundstage, depth, and openness

Our take on the brand
Specially shaped magnets allow sound waves to pass through without interference, minimizing diffraction and distortion for a cleaner, more accurate soundstage.
A precisely engineered grille reduces reflections and refractions, enhancing openness, imaging precision, and overall acoustic purity.

- Easy to drive with high sensitivity, though still benefit from a dedicated amplifier.
Product Considerations
- Some reviewers find the bass lacking in punch, preferring a more pronounced bass response.
- Treble might sound a touch bright and fatiguing, depending on the music and amplification.
- Build quality isn't mind-blowing for the price; made of plastic and metal, not always appropriate for long-term durability.
- Stock cable isn't the most wonderful, a little bit stiff.
Comparisons (according to reviewers)
- Vs Audeze LCD-X 2020: Arya Stealth has better resolution and soundstage, but the LCD-X has a more visceral bass and organic sound.

- Vs Sennheiser HD800S: Arya has a slightly V-shaped profile, while the HD800S is smoother with a more neutral tuning; both trade blows equally regarding soundstage, imaging, and resolution.
- Vs HiFiMan Sundara: Arya Stealth has deeper bass response and cleaner sound, while Sundara is warmer and more mid-centric, with darker treble.
- Vs Sendy Audio Peacock: Arya has clearer, more transparent, and more detailed treble, but Peacock's bass is heavier and more impactful, its midrange is fuller and smoother.
- Vs HiFiMan Edition XS: Arya Stealth is more comfortable and feels better built, but both have a similar sound, with the Edition XS having a slightly punchier bass.
