- The cable is high quality with a robust interchangeable connector system for different terminations (3.5mm, 2.5mm, 4.4mm)
- Overall, the Monarch MKII is considered to have one of the best tonal balances among tribrid IEMs
- Great horizontal width and effortless imaging and layering
Product Considerations

- Bass dynamics and impact may not be strong enough for bass enthusiasts
- The treble can be uneven, with some reviewers experiencing sibilance or a metallic timbre
- The packaging and included accessories are underwhelming
Comparisons (according to reviewers)
- Compared to the Symphonium Helios, the Helios has sharper transients and tighter bass, but the Monarch MKII's midbass body stands in stark contrast to the Helios’ dipped lower mids and provides warmth the Helios was missing

Our take on the brand
Our Summary

- Clean tonality, with no stridence or sharpness in the treble, and no issues with sibilance

- Treble could sound slightly exaggerated on some tracks, though it generally maintains a smooth and refined quality
Comparisons (according to reviewers)
- Vs Hype 2: Hype 4 has better bass performance, more satisfying listen, but similar overall sound, the mids on the Hype 4 have thickness and richness, where the mids on the Hype 2 are a little thin

Video review
Our take on the brand
Our Summary
Product Strengths
- Sound signature is likely to be palatable for a wide range of people at its price point.
- Good emphasis in the upper midrange, decent timbre, good resolution, the upper midrange is upfront with the vocals, nice details, and it works well with a smooth treble.
- Very smooth treble and the absence of sibilance.
- Good dynamic bass that's nicely textured and has a decent rumble.
- Imaging is accurate.
Product Considerations
- The Truth Ear Nova does not sound better or more balanced than the Hexa, since the reviewer prefers a more balanced sound signature.
- Nova is not a thick-sounding IEM, it's quite thin.
- The midrange is chiefly defined by a cavernous suckout in the low-midrange.
- Soundstage is a little narrower than preferred.
- Shell size may be slightly large for smaller ears.
Comparisons (according to reviewers)
- Vs. Moondrop Variations: Nova is significantly cheaper and close enough in performance that one should save money and go for Nova.
- Vs. Truthear Hexa: Nova easily has a smoother treble presentation, has more dynamic bass, and is more ergonomic, but Hexa has one of the best midranges in this price tier.
- Vs. Truthear Zero: RED: Zero: RED beats Nova almost across the board in tuning and simply sounds more normal.
Takeaway: The Truth Ear Nova is commendable for achieving its tuning at its price point, especially for those looking for a V-shaped presentation or Harman-esque kind of sound signature. If the Harman IE target is to one's liking, Nova is probably as safe a choice as any of the other Harman options out there.

Our Summary
Product Strengths
- Detailed and clean sound, putting plenty of micro-details on the foreground
- Good build quality and comfortable design

- Tuning switches featured
- Open and wide soundstage
Product Considerations

Comparisons (according to reviewers)
- Approaches the FiiO FH7 closely, but is not exactly as punchy and engaging when bass notes are coming to play, FH7 has a better midrange rendition
- The FH5s gives a harder edge to treble notes, but at the same time creates a wider and more spacious soundstage
- The FiiO FD5 emphasizes warmth, smoothness, and a lush sound with prominent bass and midrange, where the FH5S has a more textured midrange, and a cleaner bass with less emphasis
Takeaway: The FiiO FH5S provides an outstanding unboxing experience and impressive features, along with a clear sound. The IEM allows for long listening sessions.
