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.

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

• Lacks impact and bite
• Headband padding is uncomfortable
• Single-entry cable is on the right side, which is an unusual placement

Comparisons (according to reviewers)

• Vs Sennheiser HD650: Differences come down to something similar to a full-range studio monitor versus a full-range hifi speaker of equal build quality and similar design, Sennheisers are geared more towards enjoying the brain-pleasing sounds of music, while you probably want to mix with the Neumanns
• 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.

• The earcups feature a rotating mechanism, making it convenient to rest the headphones around the neck
• The design is considered stylish, industrial, and unique
• The suspension headband design distributes weight evenly, making it comfortable to wear for long listening sessions

Product Considerations

• The Wraith's headband adjustment system is not very practical and requires a screwdriver to adjust
• Stock pads may not create the best seal, impacting sound isolation
• The soundstage is intimate, and the resolution is average
• The 2.5mm connectors on the earcups might limit replacement cable options
• Sub-bass can roll off with stock pads

Comparisons (according to reviewers)

• Vs HiFiMan Edition XS: The Edition XS has better resolution, clarity, and sub-bass response out of the box, but the Wraith has superior build quality, materials, robustness, and comfort
• Vs Sendy Audio Aiva: The Wraith and Aiva share a similar bass roll-off
• Vs Moondrop Venus: The Moondrop Venus costs slightly more and provides a wider soundstage and more refined sound

• Lightweight design (around 260g) and comfortable earpads make them suitable for extended listening periods
• Detailed and nuanced sound, with a well-balanced midrange and smooth treble, provides a clear and crisp listening experience without being overly analytical
• Precise imaging allows for accurate instrument placement and a good sense of sound direction
• It comes with both 4.4mm balanced and 6.35mm single-ended cables, providing connectivity options for various sources

Product Considerations

• Some feel the price is high for the level of upgrade compared to the original HD 660S, especially with other competitive options available
• While the bass is improved, it's not a bass-heavy headphone and might not satisfy those seeking a thunderous bass response
• The clamping force can be a bit tight out of the box, which may cause discomfort for some users
• The soundstage isn't exceptionally wide, which may not be ideal for those seeking a very spacious and out-of-head experience
• The build quality, while durable, does not feel as premium as other headphones in the same price range due to the extensive use of plastic

Comparisons (according to reviewers)

• The HD 660S2 is generally considered an improvement over the HD 660S, primarily due to the enhanced bass response and slightly smoother sound
• The Sivga SV023 offers a brighter, crisper sound for less money, while the HD 660S2 provides a fuller, more vocal-oriented sound
• The Harmonic Dyne G200 is more exciting and energetic, but has a less natural tonality and may be less comfortable
• The Meze 109 Pro is a better headphone in almost every way, but it is more expensive and may be a little sibilant for some listeners
• HD 660 S2 offers better sub-bass reach and imaging, but the Sennheiser HD 650 still remains unmatched for male vocals
• The HIFIMAN Edition XS sounds bigger, deeper, and wider, while HD 660S2 is more about the tonality

Takeaway: The HD 660S2 is a comfortable and well-rounded headphone with a more balanced and enjoyable sound signature than its predecessor, especially with its improved bass response. It's a great choice for those who appreciate a smooth, detailed, and easy-to-listen-to headphone for various genres.

• Vs Sennheiser HD650: The MIRPH-1 is comparable to the HD-650 without the veil and also comparable to the Clears.
• Vs Rosson RAD-0: MIRPH-1 reminds a bit of Rosson RAD-0, but Rosson was much smoother, much bassier, but also had less detail.

Takeaway: The MIRPH-1 is a well-built, comfortable headphone that delivers a smooth and relaxing listening experience. Its modular design and easy driveability make it a convenient option for audiophiles and casual listeners.
