Product Strengths
- Excellent, well-balanced tuning, especially for a closed-back headphone
- Good bass response, being tight, punchy, and hard-hitting with quality and fidelity, but not overly bassy
- Comfortable to wear, using the self-adjusting headband and comfortable pads from the E3 model
- Shares a lot of similarities with the E3, but at a lower price point
- Good soundstaging, with decent width and depth for a closed-back headphone
Product Considerations
- The Piano Gloss Black finish is prone to fingerprints, smudges, and scratches, making it difficult to keep clean
- Soundstage could be wider compared to some competitors
- Detail retrieval is good but not a standout feature and may not be at the level expected for the price, particularly when compared to higher-end headphones
- Highs can be a little spicy, and the treble can be a bit more exciting, but less refined than E3
- Pads are glued on, which may make pad replacement more difficult, while being an upside for better seal to the baffle
Comparisons (according to reviewers)
- Vs. Dan Clark Audio E3: Is 90% of the headphone that the E3 is at half the cost
- Vs. Sennheiser HD6XX: The low-end is miles better, mids are almost equally delicious, but the highs are where the HD6XX seems a tad cleaner
- Vs. ZMF Auteur Classic: The Dan Clark Audio Noire X is the more technical and more neutral ride
Takeaway: The Noire X is a comfortable, well-tuned, and versatile closed-back headphone that is a great choice for those wanting a smooth and enjoyable listening experience. It offers a lot of value and is a strong contender in its price range.

- The Bathys has more consistent audio delivery, a more robust EQ, and better overall noise isolation, while the Bowers & Wilkins Px8 is more comfortable and better built
- The Bathys has similar noise isolation performance and similar USB-C and analog capabilities, but the Sennheiser Momentum 4 Wireless has a more accurate treble response and better battery life

Our take on the brand
Product Strengths
- Excellent fit and comfortable for many users, even for extended listening periods
- Very well-balanced and tuned sound signature, often described as a warm, mature, or safe Harman-ish tuning
- Smooth treble presentation, avoiding sibilance, sharpness, or fatigue, while still retaining detail
- Good bass performance for an all-balanced armature set, with nice punch and attack, though primarily focused on sub-bass
- Very good natural tonality and timbre, avoiding a metallic or unnatural sound often associated with balanced armatures
Product Considerations
- Soundstage and imaging could be better for the price, described as average and not particularly wide or holographic
- May lack a 'hook' or standout factor in its sound quality, some find it to be a more laid-back and less engaging sound
- The shells are quite big, which may be problematic for users with small ears
- The recessed 2-pin sockets could be designed better with a deeper fit
- May sound 'boring' at mid-to-low volumes, according to one reviewer
Comparisons (according to reviewers)
- Vs Moondrop S8: RSV offers a warmer and fuller sound with a more even midrange, while the S8 is leaner and more forward, with the S8 being more engaging overall
- Vs Dunu SA6: RSV has better bass quality, while the SA6 has a slightly more pronounced treble
Takeaway: The Soft Ears RSV is a comfortable and well-tuned IEM that delivers a balanced and enjoyable listening experience. It is particularly well-suited for those who appreciate a smooth, natural sound with excellent vocal reproduction.

What competes at this price?
Our Summary
Product Strengths
- Excellent sound quality, potentially challenging cabled IEMs, with a dynamic and holographic rendering and beautiful mids and airy treble.
- Effective ANC, making it suitable for reducing ambient noise, even in noisy environments, with up to 35dB of noise attenuation.
- Good build quality, with the IEMs made of lightweight metal and Kevlar, and a sturdy charging case.
- Good bass performance, with texture and extension, punchy, without overpowering, and a powerful but tight impact.
- Wide soundstage, creating a spacious and immersive listening experience.
Product Considerations
- Connectivity issues with LDAC, especially outdoors or in areas with interference, leading to intermittent signal drops.
- Transparency mode might generate turbulence in windy conditions due to microphone placement.
- Limited codecs available, with no aptX support.
- Physical size of the charging case is large and might not be pocket-friendly.

Comparisons (according to reviewers)
- Vs Final ZE8000: Svanar Wireless offers a more W-shaped and punchy signature, greater upper mids gain, more precise imaging, and a vaster sound layering capability, while the ZE8000 sound more neutral to L shape, warmer, and have more sub bass boost and warmth.
- Vs Noble FoKus Mystique: Svanar Wireless has some emphasis in the bass, but not as much, has stronger overall imaging performance—providing a wider soundstage and the best balance between the separation and cohesion in the imaging.
- Vs HIFIMAN Svanar (wired): Svanar Wireless soundstage is taller and wider but not as deep, since clarity isn’t as sharp and clean, silence being more ”noisy”.
- Vs Sony WF-1000XM4: The Svanar Wireless presents a much more detailed, natural and sophisticated kind of sound, while Sony has bloated bass, that overwhelms everything else.
- Vs Apple AirPods Pro: The Svanar Wireless generally outperforms the AirPods Pro in sound quality.
Takeaway: The Svanar Wireless is a solid choice for TWS lovers, with a top-tier sound quality, effective ANC, and its convenience and comfort. It is innovative, less bass-heavy tuning, and overall a solid proposal.

Our take on the brand
Our Summary
Product Strengths
- Lightweight and comfortable for long listening sessions
- Warm, rich, and musical sound signature
- Easy to drive with a 32 ohm impedance and 100db sensitivity
- Versatile due to the option to use wired or wireless via the Arylic Blue Mini R2R dongle
Product Considerations
- Some reviewers feel that the build quality feels cheap, with thin plastic earcups
- The bass can be overwhelming and muddy the mids, leading to a less balanced sound
- Some find the treble response rolled-off or uneven/peaky, potentially affecting detail and soundstage
- The level of notifications from the Arylic R2R dongle is uncomfortably loud
- Isolation isn't the best for a closed-back headphone, ambient noise can still be heard
Comparisons (according to reviewers)
- Vs. Drop THX Pandas: The HE-R9 offers a more liquid sound, but the Pandas may be consistently better across a wider range of music
- Vs. HIFIMAN HE-R7DX + Moondrop Moonriver II: The HE-R7DX combo offers more clarity and neutrality, while the HE-R9 provides warmth, richness, and a better 3D soundstage
- Vs. Sony WH-1000XM3: The HE-R9 sounds noticeably better from the wired connection, but when switching to wireless mode there was very little difference
- Vs HIFIMAN HE400SE: The He400Se is slightly flatter, and the bass is much less full-bodied
- Vs. HIFIMAN Deva Pro: The Deva Pro is much more balanced, both via cable and Arylic Bluemini, where the cable was preferred, but the planar returns more details
Takeaway: If a warm, smooth, and rich sound is desired, the HE-R9 is a comfortable headphone that makes listening enjoyable. It's versatile enough to be used wired or wirelessly, but might not be the best choice if a neutral and super clear sound is desired.
