TRN announced their latest flagship multi-BA pair of IEMs, the TRN BA15 that features a huge driver configuration of 15 Balanced Armature drivers on each side, so a total of 30 BA units in a single pair, exciting isn’t it. The drivers are arranged in a three-way electrical crossover with a revolutionary tubeless wave-guide system. It features finely crafted aerospace-grade magnesium alloy ear shells, providing excellent looks for its users. The TRN BA15 has a price tag of245$.
We have seen multi-BA drivers with like 5-6 BA units on each side. But TRN has equipped 15 drivers on each channel in the BA15, totalling 30 Drivers in the pair. They precisely cover the entire frequency range from 10Hz to 40khz producing a super-detailed melodious sound output for the users. The pair features 7 x 30095 BA units for well-extended lively treble frequencies, 4 x 50060 & 3 x 60040 BA units for exceptionally detailed vocals and mid-frequencies, and a single 22955 BA unit for ultra-fast lower end response. TRN has implemented a three-way crossover design so that the BA drivers work perfectly with each other.
TRN BA15’s outer shell is made using a high-precision CNC machining process. It is made up of premium Aerospace-grade Magnesium Alloy material. The housings are carefully hand-polished and matched, before going through sandblasting and anodization. This presents the users with a robust ear shell that is pure bliss to look at. The pair is available in two different colour options, Diamond Silver and Meteorite Fire Red.
TRN BA15 features a high-quality 16-core, 240 strands Litz 6N silver-plated OCC copper cable with replaceable termination plugs. It comes bundled with 2.5mm/4,.4mm balanced, and 3.5mm SE termination plugs.
The TRN BA15 uses BA units with extremely high-sensitivity. The pair has an impedance rating of 30 ohms and a sensitivity of 100dB/mW. It can be powered easily even directly through smartphones.
