Robust Level of TRN

TA4 inherits many points of TA3 and also has some innovations. TRN's products do a good job of balancing price and quality. TRN TA4 adopts conventional electronic crossover to accurately and evenly distribute the bass, midrange, and treble regions. The implementation of both dual dynamic drivers and balanced armature helps achieve coherency throughout the entire frequency spectrum.

The Combination of Rigidity and Flexibility

TA4's dual dynamic drive is equipped with Knowles balanced armature. TRN's acoustics engineers took the TA4 to the next level with their experience on the TA3. The ultra-wide frequency response of the two dynamic drivers and the excellent resolution of the balanced armature are brought together to create exhilarating music experiences.

Two Knowles 33518 balanced armature for treble. TRN TA4 provides exquisite treble and upper frequencies.

A good pair of IEMs (when not DOA)

I have mixed feelings about the TRN TA4.

My unit arrived with one unit DOA, Linsoul customer service walked me through the process of verification and then had me destroy the failed unit before sending a replacement. These IEMs would be a 8.5-9/10 if not for the issue of DOA which, to me, points at a lack of QC on the side of TRN.

The units are a little large, but fit snugly within my ears and don't cause any pains.

The TRN TA4 has some of the best accessories for a sub $100 USD IEM. The unti includes your normal silicone eartips, but they also have a set of really sticky eartips, the closest thing would be the SednaEarFit XELASTIC brand of eartips. The included cable has interchangeable tips (with rubber o-ring, I assume for dust protection). The cable wants to maintain its original shape after multiple uses, but it may just need a better case. So, the case, it's too small, it's nice to put the extra cable and eartips in, but if you want to use it for the cable/IEMs, domt bother, you'll just cause yourself a headache when you have to untable the cable.

These IEMs made me realize I don't hate Balanced Armature drivers. The sound is full and detailed without being overbearing or shouty. I do not have the best ear, for how exact something is, but, I can tell if something if wrong, and the TRN TA4 have both wrong. I activatly wanted to listen to more songs, watch movies, and play games with these IEMs, when typically I will listen for a few hours and constantly skip to find a track that sounds good with X headphones.

- They have driver flex, you can hear those drivers crunch when you push them into your ears... Yeah, seriously, it sucks.
- Cable tangles easily
- Included case is too small for use
