Intro

Only recently TRN released the V90, a hybrid 5-driver-in-ear, now they send a pure 5-BA-driver-in-ear behind. Their 6-BA model X6 has largely failed with the critics (I didn't have the opportunity to hear the X6 myself) and now they're trying their luck again. Personally I think the BA5 is quite successful, with its typical BA sound characteristics, but the sibilants and the sometimes unnatural high frequencies disturb me a bit.

Handling

The full aluminium housing, which is the same material as the V90, is very light, ergonomically shaped and more like a Custom-In-Ear. It is very comfortable to wear when using tips that allow you to get far into the ear canal. If this is not the case, the BA5 sits somewhat wobbly in the ear and stands too far outwards, whereby the fit of the BA5 no longer fulfills the sense and purpose. With the right tips, the BA5 fits the ear perfectly.

For the first time TRN uses the connector and cable that we already know from the KZ ZSX and other newer KZ and CCA models, or TFZ. For me it is the safest connection in combination with the 2-pin connector, because the pins cannot break off and also offers a secure hold. In general, I prefer 2-pin solutions. Otherwise nothing is new about the contents of the package. A small selection of tips will be added, but nothing more.

The isolation is fine, but certainly does not offer autonomous listening.

Sound

Since the BA5 is quite tip-sensitive, different results can be achieved when listening. I use either foamtips, or the smallest silicone tips and enough to get into the ear, which has a big impact on the bass.

The bass is a typical BA bass. Quite dry, midrange accentuated, fast and precise. Nevertheless, the kick could be a bit harder. I usually prefer dynamic drivers for bass reproduction, because BA drivers often make it too sterile and dull for me, but the bass of the BA5 is really quite good in comparison and also has sufficient dynamics. The 22955 is used here, but not by Knowles but a custom version, as it can be found for example in KZ models.
The tuning was done more for balance than for prominent bass. The BA driver can actually do more, which you can certainly tickle out with an equalizer. All in all a homogeneous bass with good detail presentation and speed.

The mids are also controlled by a single BA driver (29689). These are very clear, clean and push themselves somewhat into the foreground, but the BA5 is not a mid-centered IEM. Female voices are somewhat better. I'm missing a bit of body and volume, which is also more obvious in male voices. This makes voices seem too bright for me in the beginning, but you get used to them quickly. The same applies to instruments. Basically, the mids are very relaxed, rich in detail and high-resolution and seem neither too flat nor sterile. Together with the excellent three-dimensionality of the BA5, clearly the strength of the BA5.

I don't know why the treble was given 3 BAs at all. Of course you can reduce the distortion/distortion factor, but this is only the 30095 that is often used in Chi-Fi circuits. In my opinion these are difficult to individualize and tune, because they always have a metallic basic timbre and tend to unpleasant peaks. Nevertheless, I have to admit that the BA5 did quite well. The highs are generally in the foreground and bring a lot of details with them. However, they don't always sound natural, so you have the feeling that artificial sounds have been somewhat exaggerated. In addition, the sibilants are very strong, which of course depends on the voice, but they are always present. Here I would wish for a softer tuning and would also accept detail cutbacks, respectively would also minimize the artificiality. Nevertheless it is fun to listen to some tracks with the BA5 for a certain period of time, but for me it is not a permanent solution.

What makes the BA5 really good is the stage and its spatial arrangement. The BA5 sounds open, certainly also favoured by the quite bright tuning and voices distinguish themselves very well from instruments and effects. I would say that this is where the strengths of the BA5 lie.

Outro

The BA5 is a good representative of the pure multi-BA driver models on the market, which impresses above all with its feel and fit. In terms of sound, it's more for fans of higher frequencies if you don't have an equalizer at hand. Nevertheless, I find the bass and mids very harmonious. One could say that if TRN now combines the bass and mids of the BA5 with the highs of the V90, a very round product should come out. So for my taste the BA5 is rather something for lovers of pure BA sound.
