2. Design And Build Quality
The Moondrop Kato sports an all-metal construction with solid stainless steel machined housings. Fit and finish are excellent, conveying a premium feel. While built to last, the metal does add a noticeable weight. The 7Hz Timeless features aluminium alloy shells with a unique circular, planar disc shape. They feel sturdy, though the two halves exhibit a visible seam line. The metal build seems durable but contributes to a heavier weight as well.
Both models come with detachable cables terminated in 3.5-mm plugs. The connectors inspire confidence, though Timeless uses MMCX connectors, which have more durability concerns long-term. Overall, build quality is excellent on both, but the extra heft could bother those sensitive to heavier IEMs. The Kato takes a slight edge for its seamless shell design and secure connectors.
Verdict: Moondrop Kato
3. Comfort
Despite their metal construction, both the Kato and Timeless offer surprisingly comfortable fits for most ear shapes. The Timeless' short, angular nozzles allow them to sit flush in the ear. Smaller ears may experience contact with the angular shells. The Kato's nozzle length achieves a good seal, though the shapely metal housing rests heavily in the outer ear over time. Noise isolation is about average on both. While comfort is quite subjective, most should find either set suitable for moderate listening sessions. For all-day use, the Timeless' lighter weight gives it a small advantage in long-term comfort.
Verdict: 7Hz Timeless
4. Sound Quality
I. Tonality
The Moondrop Kato pursues a mild V-shape signature with a slightly boosted bass and sparkly treble around neutral mids. Its overall tonality aims for harmonic realism and accessibility to various genres. The 7Hz Timeless has a more pronounced V-shape, with a bigger bass lift and additional lower treble emphasis. This provides an exciting, engaging sound compared to the more natural Kato. Those wanting an analytical, fun sound will prefer the Timeless, while the Kato suits listeners craving accurate timbre and minimal coloration.
Verdict: tie (depends on preference)
II. Frequency Response Graphs
III. Bass Response
Low-end performance is an area where the different driver technologies are apparent. The Kato’s dynamic driver bass provides pleasing extension with a natural decay. The texture is admirable. In contrast, the Timeless’ planar driver delivers impressive sub-bass rumble paired with a bit of bloat and slower decay in the midbass. Both avoid muddiness in the lows. While the Kato bass sounds tighter and more realistic, the Timeless provides that deep visceral engagement certain genres call for. Bassheads who crave subwoofer-like lows will really appreciate the Timeless’ incredible extension.
Verdict: tie (depends on preference)
IV. Midrange Performance
The Moondrop Kato’s midrange shines, excelling in clarity while retaining a natural tonality. Instruments have an appropriate body, and vocals sound realistically smooth. Meanwhile, the 7Hz Timeless’ lower mids can come across as slightly recessed due to the bass and treble emphasis. This gives them a cooler, more analytical tone. Upper mids are vivid but have a tendency to sound somewhat shouty. Overall, the Kato provides a more accurate and fatigue-free midrange for long listening sessions. Vocal lovers will really take to its lifelike and detailed performance.
Verdict: Moondrop Kato
V. Treble Response
Both models have elevated lower trebles for added sparkle and air. The Kato manages this without harshness or sibilance. Meanwhile, the Timeless can occasionally sound slightly hot around 8 kHz. Its crisp attack trails into a smooth decay, avoiding sharpness. The extension is excellent on both. Overall, the Kato strikes a better balance between detail and non-fatiguing quality in the treble range. The Timeless provides that extra low treble energy some may favour for an exciting presentation. Those sensitive to hot trebles should opt for the Kato.
Verdict: Moondrop Kato
5. Technicalities
I. Soundstage And Imaging
When it comes to soundstage properties, Timeless pulls ahead noticeably. Its spacious width and impressive depth create an immersive presentation, while the Kato sounds more intimate. However, the Kato edges out the Timeless for imaging precision and instrument placement on the stage. The Timeless conveys a better sense of space, but the Kato wins for accuracy. For pure soundstage size, the Timeless is the winner.
Verdict: 7Hz Timeless for soundstage size, Kato for imaging
II. Instrument Separation And Detail Retrieval
On critical listening, the 7Hz Timeless showcases the benefits of its planar driver, delivering excellent instrument separation and articulating micro-details with ease. The speed and low distortion make it sound more clinical and analytical compared to the dynamic driver, Kato. Both avoid congestion, but the Timeless retrieves ambiance cues and subtle textures that the Kato misses. The Kato is no slouch for a single DD, but the Timeless takes the category with its technical precision.
Verdict: 7Hz Timeless
III. Dynamics And Speed
The Timeless impresses again here with its quick transient response and crisp note attacks. Drum impacts have a suitable punch, though a bit more nuance would be welcome. The Kato provides nice dynamics and avoids bloating or muddiness in busy tracks. For outright speed and precision, the Timeless leverages the inherent advantages of planar technology to deliver mesmerising performance. The Kato puts up a noble effort for a dynamic driver, but the Timeless wins handily.
Verdict: 7Hz Timeless
IV. Resolution
Complementing its stellar transient response, the 7Hz Timeless offers amazing resolution that competed well above its price bracket upon release. It reveals fine nuances and textures that the Kato glosses over. The Kato itself performs admirably for a $200 dynamic-drive IEM. But ultimately, The Timeless provides a more analytical, detailed window into recordings. Its planar pedigree grants clarity and insight unmatched at the price point.
Verdict: 7Hz Timeless
6. Gaming Performance
For gaming usage, the Timeless' expanded soundstage grants better spatial awareness than the more intimate Kato stage. However, the Kato has superior imaging precision for competitive play. The Timeless' analytical detailing also helps convey in-game sound cues. Ultimately, the Timeless would likely be preferred for immersive single-player adventures, while the Kato's imaging makes it better for competitive online play requiring pinpoint accuracy. Either model works reasonably well for casual gaming.
Verdict: Draw (depending on the intended use case)

8. Conclusion
Breaking down every category, it's clear these two IEMs have unique strengths and will appeal to different listener priorities. The Moondrop Kato earns praise for its natural tonality, realistic midrange, and refined treble. It provides an engaging yet fatigue-free sound. Meanwhile, the 7Hz Timeless impresses with its huge planar bass, vivid clarity, and outstanding resolution. Soundstage space is vast, and imaging is quite good.
In terms of pure technical performance, Timeless is the winner. But some may find its tuning flaws, like the recessed lower mids and occasionally hot treble, bothersome in the long run. At the end of the day, choose the Kato if you want beautiful tonality and cohesion suited for long listening. Pick the Timeless if you crave a planar experience with awesome speed, dynamics, and detail. Either model represents a solid option around $200 that outperforms its price. Your music tastes and sonic priorities will dictate which is the better choice to spark your musical passion.
