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.

Reviews
HIFIMAN is a hifi brand known for its planar magnetic headphones that use extremely thin diaphragms and acoustically transparent "Stealth Magnets" to reduce sound distortion. The company pioneered high-resolution portable audio players and creates electrostatic headphones that bring high-end sound quality to more accessible price points, as well as widely renowned flagship models such as the Susvara.
Check Amazon
Expand Details

Product Strengths

  • Sounds big and open for a closed-back headphone, with an impressive soundstage for its type.
  • Offers a warm-leaning, smooth, mid-forward sound signature.
  • Very good imaging creates an immersive listening experience, and detailed separation of instruments.
  • Easy to drive with a low impedance and high sensitivity, making it suitable for use with portable devices.
  • The wooden earcups have a large internal space that brings sufficient volume and breathing room to the driver.

Product Considerations

  • Build quality may be disappointing for the price, particularly the headband, which is considered cheap compared to other headphones in the price range.
  • Comfort can be an issue due to the weight and headband design, which may cause discomfort on the scalp for some users.
  • Lacks clamping force, so the weight is felt on the top of the head, and it does not isolate sound very well.
  • Treble response might be somewhat softer or less energetic compared to other headphones, which might not appeal to those seeking a more exciting sound.
  • One review mentions an issue with a dip around 5kHz and a peak around 10kHz that impacts some instruments, though it is admittedly 'nitpicking'.

Comparisons (according to reviewers)

  • Vs HIFIMAN HE-R10D: There is a difference in price and sound signature.
  • Vs HIFIMAN Susvara: The HE-R10P has less soundstage, the Susvara has more transparency, but the HE-R10P has more mid-bass presence.
  • Vs Focal Stellia: The HE-R10P has a larger soundstage and more powerful bass, but Stellia has a safer tuning with a brighter high end.

Takeaway: The HiFiMan HE-R10P is a closed-back planar headphone that delivers exceptional sound quality with remarkable imaging and detail, making music sound lively and fun. Its unique design aims to create an open and spacious listening experience, allowing listeners to enjoy music for hours.

Reviews
Subtonic Audio is a hifi headphone brand recognized for their SLAM dual-armature woofer system, delivering bass extension down to 3 Hz, and their complex 7-way CTRL crossover that splits signals into narrow bands for precise control. Their flagship Storm IEMs showcase hand-enameled faceplates with a two-thirds rejection rate.
Check Amazon
Expand Details

Product Strengths

  • Considered by many as having the best sound achievable in an in-ear headphone, making it an exceptional audio experience
  • The sound signature is mostly balanced with tasteful coloration, where the treble imparts a particular element that is potentially preferable
  • The midrange is extremely well done
  • Features unique SLAM subwoofer, woofer, midwoofer, mid tweeter, tweeter and EST technologies
  • Built with Grade 5 titanium, providing sturdiness and high quality

Product Considerations

  • Treble performance can be hit or miss depending on the listener's anatomy and HRTF
  • Requires more power than typical IEMs, potentially draining the battery of portable audio players
  • Shells are on the larger side
  • The included cable is nice, but the chin cinch tends to slide down

Comparisons (according to reviewers)

  • Compared to the Hi-Senior Megafest and Dusk Default DSP, the Storm is an editorialized or enhanced version of those IEMs, particularly regarding bass and mids
  • Compared to the 64 Audio U6T, it has similar balance with similar tasteful colorations, but Storm's bass is more punchy and the upper treble is more to the reviewer's preference
  • Compared to the Empire Ears Odin, the Storm is preferred because the Odin is not as versatile, and the Storm sounds more detailed
  • Compared to the Empire Ears Raven, the Storm is more normal in a good way because the Raven has massive bass and a strange lower midrange resonance feature
  • Resolution, stage and tonality are better on the Storm compared to Grand Maestro

Takeaway: The Storm is a high-end IEM with exceptional sound quality and great build, even if pricey. It could be worth buying for those who want the best possible audio experience and appreciate a balanced sound with unique features.

Expand Details

Our Summary

Product Strengths

  • Gorgeous IEM with a finish worthy of a top-of-the-line IEM, pictures not doing it justice
  • Highly revealing, with incredible detail and microdynamics that deliver a vivid, lifelike reproduction of music
  • Excellent speed and strong texture in the balanced armature based low-end
  • Clean, detailed, and transparent mids with top-tier detail retrieval coupled with strong layering and separation
  • Soundstage is wide and three-dimensional, with holographic imaging, giving a real sense of being on stage or in the studio with the performers

Product Considerations

  • The IEM is on the larger side, so consider this if you've got smaller ears
  • Ronin is bright and has energetic treble, which may not be preferred by those who like a warmer sound with bass emphasis
  • Bass is more neutral, and it's not going to have the impact of a dynamic driver bass
  • Treble can be somewhat unforgiving, highlighting unpleasant aspects of older or lower-quality recordings
  • Some reviewers found the character of Ronin to be a little bright and sometimes bass-lite, and may need proper pairing to sound its best

Comparisons (according to reviewers)

  • Vs Empire Ears Odin: Odin is more versatile, but Ronin's treble performance is at a higher level
  • Vs 64 Audio Fourte Blanc: Fourte Blanc offers a more balanced sound overall, while Ronin leans towards a more technical, bright sound
  • Vs Noble Viking Ragnar: Ragnar has more rumble and denser, deeper layers of bass, while Ronin has slightly higher resolution
  • Vs Noble Sultan: Ronin has more details, while the Sultan is more weightier and warmer in representation

Takeaway: The Noble Ronin offers incredible detail, imaging, and resolution, delivering an immersive listening experience for those who appreciate a highly revealing sound. For those with a collection of high-resolution music who want to hear every nuance, the Ronin is an excellent choice.

Expand Details

Our Summary

Product Strengths

  • High-quality build and materials, with CNC-milled aluminum shell and Raffir composite faceplate, which gives a jewelry-like element
  • Great imaging with a big soundstage, good instrument separation, and placement
  • Excellent vocal imaging with a forward, intimate, and balanced vocal presence that avoids sibilance
  • Deep bass extension with physical characteristics (bone conduction driver), and good texture across the entire range

Product Considerations

  • Fit can be tricky due to the larger size, potentially problematic for those with smaller ears, but a deep penetration ensures a good seal with the right ear tip
  • Can be source-sensitive, and might become muddy with warmer sources—more reference or incisive sources are recommended
  • Bass bloom can overwhelm the mids on some recordings

Comparisons (according to reviewers)

  • Vs Vision Ears VE10: The Onyx has a massive arena-like soundstage, while the VE10 feels more like a studio; the VE10 has stronger mids and more extended treble, but can be shouty
  • Vs U12T: The Onyx has more focused and bodied vocals, and the bass provides better pressure and control, while the U12T has greater clarity
  • Vs Aurora: The Onyx offers more precise and lively sound with better bass, and a more realistic vibration

Takeaway: The Noble Audio Onyx has a great build and delivers a unique, dark sound signature with a wide soundstage. With a good blend of bass, smooth highs, and clear vocals, the Onyx provides a great listening experience, especially for genres like rock and metal.

Our Summary

Product Strengths

  • Lovely tuning balance across the board, backed by a wonderfully holographic and immersive soundstage that keeps the listener deeply involved without fatigue
  • Excellent channel balance from left to right, but holographic layering and cavernous presentation will engulf the listener in the presentation
  • Noble Audio's hardest hitting tuning yet, with a combo of fast, physical bass, deep extension, and the brand’s signature top end detail and clarity
  • Visually stunning design with intricate Japanese-themed aesthetic
  • Excellent passive isolation

Product Considerations

  • Slightly dark lower-treble
  • The shell is sizable which could feel big in some ears, and the initial insertion might feel cumbersome
  • The Shogun’s aesthetic design may be 'too much' or 'too gaudy' for some
  • Bass texture might not be as present as expected for the price range
  • Mids and highs could use a bit more energy

Comparisons (according to reviewers)

  • Vs Noble Ronin, the Shogun has a warmer, heavier sound
  • Vs Empire Ears Raven, the Raven has a deeper, stronger subbass response, while the Shogun emphasizes the midbass and low mids a little more, the Raven also adds a bit of an extra pop in the vocals

Takeaway: The Shogun is an all around great IEM that adds a little more warmth and color to Noble’s flagship lineup and stands strong among the competition. It's worth checking out if you want a balanced sounding, flagship quality IEM with hard-hitting bass and impressive spatial imaging.

Our Summary

Product Strengths

  • Beautifully balanced tonal quality
  • Excellent and innovative shell design
  • Unique unboxing and premium accessories
  • Comfortable fit despite the larger shells
  • Wide stereo separation

Product Considerations

  • Treble might seem too controlled for some

Comparisons (according to reviewers)

  • Compared to 64 Audio’s Fourte and the Vision Ears Phonix, the Enigma competes with them in the summit-fi range
  • Compared to Softears Twilight, the bass is tighter and more focused, with better detail, also the Enigma has a more precise and layered soundstage
  • Compared to Elysian Annihilator, the Enigma trades the sharp precision of the Annihilator for a smoother and more forgiving presentation
  • Compared to Empire Ears Odin, the Enigma is easier and more laid back to listen to, whereas the Odin grabs attention with its bold dynamics
  • Compared to Lime Ears Anima, the Enigma feels more refined in comparison, excelling in accurate ear gain/upper-midrange, which results in it sounding more linear and natural
  • Compared to Kinera Loki Emerald, the Enigma outshines the Loki in mids, offering a more natural and emotive presentation
