TRN Rosefinch marks the entry of an all-new pair of high-fidelity in-ear monitors equipped with a 12mm large full-frequency planar magnetic driver unit. The pair boasts an exciting design with a semi-open grill on high-quality aluminum alloy face covers attached to imported resin ear shells. The pair has been tuned professionally to produce an immersive sound with a wide 3D soundstage. TRN has adjusted the tuning of the latest Rosefinch to complement different genres with a rich tone, unparalleled clarity, and an expansive 3D soundstage!!

Full-Frequency Planar Magnetic Driver

TRN has featured a 12mm large full-frequency ultra-thin diaphragm planar magnetic driver unit on the Rosefiinch. A planar driver functions differently than a dynamic driver unit. Instead of a cone-shaped diaphragm, it adopts a flat diaphragm that is capable of producing crispier sound with faster transients and an expansive soundstage. The bass impact is also tighter and better controlled with planar magnetic drivers. The driver here on the Rosefinch adopts an ultra-thin 2um diaphragm.

Symmetrical Dual-Sides Magnetic Architecture:-

TRN Rosefinch adopts a dual-sided Neodymium N52-based high-power magnetic array structure on the 12mm planar magnetic driver. It produces a high-power magnetic flux that allows for swift movement of the diaphragm coil resulting in a cleaner, richer, denser sound with low distortion in the output signal. The pair is able to achieve a natural tone with outstanding dynamics and great extensions.

3D Expansive Sound With Professional Tuning Adjustments

TRN has professionally adjusted the tuning of the Rosefinch with a dedicated team of audio engineers. The tuning here has been adjusted to deliver a rich sound with an impactful lower end, lovely vocal clarity, and crisp separation for both instruments and vocals. The pair delivers an impressive sound with a wide soundstage presentation. It basically complements different genres of music with its clarity, resolution, and details.

Beautiful Build With Semi-Open Cavity Design

TRN Rosefinch features a semi-open back cavity design with high-quality aluminum alloy face covers. These are crafted using a high-precision 5-axis CNC machining process. The face cover is attached to high-quality skin-friendly imported resin material ear shells. Resin material gives the shells a lightweight build structure.

High-Quality Stock Cable

TRN bundles the latest Rosefinch with a high-quality stock cable. It adopts a 4-core silver-plated copper and oxygen-free copper hybrid cable with a modular termination plug system. This cable brings the benefits of both SPC copper and OFC copper materials giving fullness to the sound. A swappable termination plug allows you to easily swap the plugs and use your own choice of termination. Please note that the package includes only a 3.5mm single-ended plug. You can buy the other terminations separately(2.5mm/4.4mm).

Build quality

Build quality meets the price standard.

 

It is beautiful and sturdy in construction. I am concerned about the design utilizing a slit shape that I have seen somewhere before, but let's not go into it. They may claim that the design was inspired by the feathers of a vermilion bird, but audiophiles would consider it too much influenced by a more immediate object than an imaginary creature, namely a rival brand of earphones.

 

Rival KZ has recently been molding beautiful housings with its own design, but TRN may be paying too much respect to other brands.

Fit

The fit is good. The inside of the design is quite rounded, so it is gentle against the ear.

Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.

 

TRN Rosefinch has a V-shaped sound signature.

 

Please see here  for detailed reviews on sound quality.

Lows / Bass

The bass on the TRN Rosefinch is a bit expansive but reaches reasonably deep.

 

The bass drum does not sound bad in terms of tightness, but it seems to lack a bit of weight, sounding closer to tapping rather than thumping.

 

The electric bass also tends to be bright and may be slightly lacking in terms of blackness.

 

The lower midrange is a bit cluttered, as the bass, while light-ish, is more present in volume than the midrange. Either way, bass lovers will not find the sound very appealing.

 

TRN Rosefinch

 

Mids

The midrange of the TRN Rosefinch is tuned for three-dimensionality, with a concave center.

 

Staging is considerably emphasized and depth can be felt, but the midrange tends to be cramped and horizontal, making it somewhat difficult to hear. The angle of the midrange as a whole is slightly more forward leaning, so guitar edges and vocals feel as if they are extended from the back.

 

The high-frequency direction is adjusted to be fairly neutral, and the linearity is not bad, so the sense of localization is rather accurate despite the forward tilt. However, the overall structure of the midrange is a typical V-shape, and the adjustment is consumer-like, so it is not suitable for audiophiles who tend to be particular about the accuracy of the sound image in the midrange in general.

 

The resolution is very high and the transparency is excellent, making it an excellent midrange in terms of audio specifications.

 

TRN Rosefinch

 

Highs / Treble

The TRN Rosefinch takes advantage of its planar drive design to provide very extended high frequencies.

 

The highs are quite excellent, with high linearity, a fairly stable sense of localization, and not much lack of detail. Subtlety may be a bit lacking, but there is plenty of exhilaration.

 

However, from the center of the midrange, the highs tend to be quite assertive, so they tend to have a strong tendency to have a shaky or crunchy atmosphere depending on the song. This tends to produce a sense of glare, and there is a tendency for the sound to sound metallic and dry.

Sound quality general comment
  • Original Sound Fidelity: A
  • Recommendation: A-
  • Personal preference: A-

 

TRN Rosefinch IEMs are reminiscent of the new era of planar-driven drivers. It demonstrates the excellent range characteristic of planar-driven drivers, while offering high transparency and very good resolution, and it is clear that TRN has been trying to take the lead in this area.

 

Rival KZ is still struggling to improve transparency even with the KZ PR1 Pro, and TRN may have a clue as to how to overtake KZ by achieving terrific resolution and high transparency comparable to dynamic drivers with the Rosefinch.

blog.ear-phone-review.com

 

However, KZ still has the edge in midrange sound production and overall sound balance, and it is unclear whether TRN Rosefinch will be able to overpower the PR1 Pro and KZ's new planar drive earphones that are expected to appear in the future. In terms of price advantage, TRN Rosefinch is considerably better than the PR1 Pro, but it may not be as highly regarded, as Rosefinch's surprisingly peaky and differentiated sound is not likely to be everyone's cup of tea.

 

Rosefinch is therefore a product that is still at the middle-of-the-road level, but the tremendous performance demonstrated by this product suggests that TRN's planar-drive models in the future could, in some cases, be the eye of the storm for the entire earphone industry.

Pros
  • Lustrous sound
  • Good original sound fidelity
  • Excellent resolution on par with ultra-high end
  • Transparent and clear midrange

General comment

TRN Rosefinch represents a completely new step forward for TRN in the field of planar-drive earphones. With its well-defined high frequencies, carefully tuned and consistent sound design, high transparency, and above all, ultra-high-end resolution, TRN has revolutionized the planar-driver earphone segment. However, its sound balance, which is not well-developed in the midrange, is unfortunately not suitable for audiophiles.
