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.

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.

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
• The sound is source dependent
• More mid-treble and air up top, lesser fullness in lower-midrange, and less of the mid-bass boost would be ideal

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

Takeaway: The Softears Enigma is a well-balanced high-end IEM, with craftsmanship and attention to detail evident in its distinctive design and thoughtful packaging. If one favors a sound that leans toward musicality with a relaxed tuning, the Enigma is sure to please.

Product Strengths

• Custom, personalized fit due to custom molding, offering comfort and secure fit
• Excellent acoustic isolation, effectively blocking out external noise
• High sensitivity, making them easy to drive with various sources
• Astonishing sound with a high level of detail and clarity
• Durable build quality

Product Considerations

• High price
• Deep canal fit may not be comfortable for all users
• Requires external EQ tweaking to achieve optimal frequency response, as the out-of-the-box tuning may not be ideal
• The included case design can be unwieldy and annoying to open
• Ambient port plugs are small and can be easily lost

Comparisons (according to reviewers)

• Simpler implementation of drivers in the Sennheiser can yield better results

Takeaway: The Premier are a high-end custom in-ear monitor option with excellent sound reproduction, build quality, and personalized fit. For those who prioritize sound quality and custom fit, the Premier could be worth the investment for critical listening or professional use.
