(Chi-fi IEM Review) TRN TA2: Not bad if you like a dense, warm sound, but it's a non-mainstream sound in TRN.

Sound quality description

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


The TRN TA2 has a narrow V-shaped sound that is focused in the midrange. The sound image is slightly condensed in the front, making it easy to understand the overall picture of the music, but also making it sound cramped. The mid-range is dense and dense, and the vocal image can be heard loudly, with a rather high sense of fullness and high resolution, so it is surprisingly worth listening to, but it lacks dynamism, and the sound field tends to be flat.

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


It's hard to rate this model. The cheaper TRN MT1 (okcsc ED10) and the more expensive TRN VX Pro are both relatively good, so the TRN TA2, with its middling overall performance and few positives other than resolution, is easily overshadowed and placed in the non-mainstream camp.


In many cases, it is better to buy the MT1 than the MT1, and if you buy more from the MT1, the VX Pro is better in terms of sound balance and use. In other words, unless you want to have a complete collection of TRN products, it's better to just pass on it.

General comment

The TRN TA2 is a listening earphone with a dense sound. It's not bad for relaxing and enjoying music, but many people will find it too quirky, lacking in detail reproduction despite its high resolution, and overall fuzzy. Not only are there many better earphones in the same price range, but even the TRNs tend to be an even bigger letdown since there are other reputable and excellent options nearby, such as the MT1, which you can get for less, and the VX Pro, which you can buy with a little patience.
