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
- Very comfortable for an on-ear headphone, even with stock pads, due to its light weight
- Sound is enjoyable, making the listener focus on the music rather than picking apart the headphones' performance
- Easy to drive, sounding great off various sources, like dongle DACs, phones, and dedicated amplifiers
- Impressive bass response, being full, detailed, and dynamic—comparable to some closed-back headphones

- The headband design looks and feels cheap
- Balanced cable may have quality issues
- May not be ideal for those seeking a super airy and clear mid-range or the crispest treble details
Comparisons (according to reviewers)

Product Strengths
- Excellent resolution and detail retrieval, making it a clear step up from mid-fi headphones

- Comfortable design, with well-distributed weight, large earcups, and comfortable earpads
- The Arya Organic is easier to drive than previous Arya versions and sounds better with various equipment, responding well to a decent system
- Balanced and neutral sound signature, though some find the treble slightly bright
Product Considerations
- Noted to lack dynamic weight and bass slam, which might disappoint bass enthusiasts
- Treble response can be fatiguing depending on the music and is somewhat peaky

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
- The Arya has a larger soundstage, but the Focal Clear has better punch and slam

Our take on the brand
Product Strengths
- Stunning aesthetics and high-quality craftsmanship with various wood options and grill designs available
- Creates a wonderful sense of space with a great spherical soundstage and natural depth
- Has an amazing ability to be both smooth and detailed at the same time
- Provides a deep reaching and encompassing bass sound with a punchy and impactful profile
- Natural and lifelike tonal quality with vibrant midrange and textured vocals
Product Considerations
- Not ideal for those seeking maximum detail retrieval or a reference-level sound
- May not be the best choice for music that relies heavily on aggressive, distorted electric guitars due to potential mid-range harshness
- Bass extension may not reach as deep as some planar headphones
- The stock cable has shape memory, and some may prefer aftermarket options
- It's a heavier headphone, so comfort may be a concern for some users
Comparisons (according to reviewers)
- Vs ZMF Verite: The Atrium sits alongside it, and is a significant step above the Auteur, in the sense that it is competing absolutely with the Verite, whereas the Auteur doesn't quite reach the heights of the Verite
- 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
Takeaway: The ZMF Atrium offers a beautiful design and a unique sound signature that combines smoothness and detail, making it a very enjoyable listening experience across many genres. Its ability to create a lifelike and engaging soundstage makes it a worthwhile option for those looking for something special.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Unique octagonal design made of quality materials, with a rugged, serviceable build quality featuring exposed nuts and bolts.
- Surprising amount of bass for an open-back, on-ear headphone, that is solid, tangible, present, well balanced and well tuned.
- The silver-plated OCC copper cable is lightweight, pliable, ergonomic and does not remain bent after staying still.
- Comfortable on-ear headphone, especially considering it's an on-ear design, with thick, soft pads and a comfortable headband.
- Easy to drive with portable devices like dongles or smartphones.
Product Considerations
- Being an on-ear design, the Thalia can become uncomfortable after extended listening sessions (45 minutes or longer) due to pressure on the ears.
- Not the most compact headphone, and does not fold up, limiting its portability somewhat.
- The open-back design results in sound leakage, making it less suitable for noisy environments or situations where discretion is required.
- The height adjustment mechanism, while providing fine control, is a bit fiddly and not easily adjustable on the fly.
- Its lower-midrange will be too full for some.
Comparisons (according to reviewers)
- The Thalia is far superior to the Koss Porta Pro and sets a new standard for portable on-ear headphones, but it is inspired by the Porta Pro.
- Compared to the Grado RS2x, the Thalia is more durable, comfortable, and more enjoyable overall, and is more bassy and thicker in the midrange.
- The Thalia has a faster pace and a better driver control, and offers a lot more in the top-octave than the Sennheiser Momentum 2/3.
Takeaway: The Thalia is a uniquely designed, portable on-ear headphone that delivers great sound and is built to last. It is a good option for those who want a distinctive headphone that is fun to listen to.

Our take on the brand
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
- Provides good detail retrieval, resolution, and transparency of sound, the drivers can show plenty of information and micro detail
- 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
- Vs HiFiMan Arya Stealth: Has a better build quality and bass response
Takeaway: The FiiO FT7 is a well-built, comfortable headphone that offers a neutral-leaning-warm sound that can be tailored with different earpads. The FT7 competes with other headphones that cost significantly more, making it a great pick at its price point.

Our take on the brand
Our Summary
Product Strengths
- Excellent stereo separation for mixing and monitoring
- Built with aluminum, it has a durable feel
- Designed for reference listening
- Clean, linear, and very detailed mids
Product Considerations
- Sound can be considered somewhat restrained, lacking upper midrange and low to HF 'hype'
- Cloth ear pads may not feel as soft or luxurious as velour pads on some other headphones

- Headband padding is uncomfortable
- Single-entry cable is on the right side, which is an unusual placement
Comparisons (according to reviewers)

- Vs Sennheiser HD600/650: The HD600 and HD650 are more comfortable, with a better industrial design than the NDH-30
Takeaway: The Neumann NDH 30 is a tool that can be very helpful for mixing sessions, especially for identifying details in the mid-range of a mix. Its design and build quality also make it a lasting product.

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.
Our Summary
Product Strengths
- Very comfortable, even for extended listening sessions, due to a suspension strap design and large earcups.
- Soundstage is large and open, creating a concert-like experience with sounds coming from a distance and feeling like a three-dimensional experience.
- Deliver detailed and transparent sound, making it possible to hear all the nuances in music.
- 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 HiFiMan Ananda: Arya Stealth is better, with more bass, crisper resolution, and a bigger soundstage; everything is sharper, clearer, better resolved, and more refined.
- 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.
Takeaway: The Arya Stealth Magnets are great for listeners looking for exceptional imaging, transparency, and clarity in their music, offering a high-end sound experience with a spacious soundstage.
