Appearance Design – Accessories
TRN Conch is designed with conch as inspiration. This design has two advantages – one is that it can fit closely to the auricle when worn, providing a stable wearing effect; the other is that it has an acoustic effect. The liquid metal material used in TRN Conch earphones has a certain inhibitory effect on the resonance generated by the dynamic driver during operation. Liquid metal cavity + electroplating mirror process, the texture is better than that of resin transparency plastic earphones.
TRN Conch gives away a lot of eartips – 7 pairs of eartips. In addition to regular silicone eartips and memory foam eartips, T-eartips developed by TRN are also given away. The supporting effect of T-eartips is better than that of conventional silicone T-eartips, which can have a positive effect on sound transmission and further optimize the timbre of the treble.
The other is the headphone cable, 4-core silver-plated copper wounded and oxygen-free copper braided interchangeable plug cable – which effectively improves the fullness of the sound while enhancing full-frequency resolution.
Supports 3.5mm, 4.4mm and 2.5mm plugs that can be replaced. Supports replaceable tuning nozzle filters, providing three nozzle filters choices – Reference (black ring), Translucent (blue ring), Atmosphere Enhancement (red ring).
Acoustic Configuration and Sound Description
TRN Conch has a built-in DLC composite diaphragm dynamic driver – this type of diaphragm has the characteristics of strong rigidity, fast response, resolution and high-frequency extension. In addition, TRN has equipped it with the dual magnetic circuit design to optimize the magnetic flow, and the acoustic cavity structure and front cavity air holes have also been acoustically optimized.
The low-frequency quantity is moderate, the closing speed is fast, it can bring out a good sense of abundance and thickness, and the extension is deep enough. Supplemented by comfortable rebound, clear layering, and a loose and majestic striking area. The Conch’s low frequency is clean and can create a natural and powerful atmosphere.
The mid-frequency vocal distance and mouth-shaped size are relatively moderate, with good thickness and realism. The imaging is condensed and the lines are solid. It is durable but not irritating, full and not straightforward. Whether it is the deep magnetism of a male voice or the sweetness of a female voice, they can easily control it.
The high-frequency is TRN Conch’s absolute strength. It’s hard to imagine hearing such rich details on a pair of $35 earphones. It is swaying freely, transparency and bright, and every note seems to have been carefully polished, rounded, smooth and melodious. Moreover, the high-frequency is also very solid and steady, not uncontrolled – ensuring the accuracy and smoothness of the instrument’s restored timbre.
The impedance of TRN Conch is 30Ω, and the driving requirements for the front end are very low. It has three tuning nozzle filters: Reference, Translucent and Atmosphere Enhancement. Let’s talk about my favorite atmosphere enhancement filter first – the sound of this filter is very energetic, and the contours of the lines are very clear, which is very suitable for listening to pop music. Its low-frequency extension is deep, and the reverberation is relatively rich; it has plenty of power under fast-paced music, and the earphones are better at handling burrs on the edges of lines.
If you don’t like the sound of stimulate, I recommend the translucent filter. The sense of stimulation of the overall sound will be significantly reduced, and more attention will be paid to the balance of tri-frequency. At this time, the low-frequency will appear cleaner and clearer, and the extension is obviously less than that of the atmosphere filter, but the extension speed is faster, the elasticity is excellent, and the cohesion is more natural, without any dilatory feeling. Plus, the instruments under translucent filter sound very good, especially the string presentation. The soundstage is not very wide, but the sound is layered and the overall transparency is also excellent.
I rarely listen to the reference filter, I just briefly listen to it and then change it to other else. The overall sound is obviously much calmer, it mainly emphasizes ultra-low distortion and control of sibilance, and it is a relatively plain sound – it has no distinctive features and is mainly pleasant.
Conclusion
TRN Conch may not be a pair of earphones that can surprise me greatly with its sound. But for friends with a limited budget, it is undoubtedly a victory of the times to be able to buy such comprehensive earphones with no shortcomings and very strong universal tuning for 35 US dollars.
