Intro:
The TRN BA5 is an all balance armature IEM with 5 drivers per side. Each side utilizes three 30095 BA drivers for highs, one 29689 BA for mids, and one 22955 BA for low frequencies.
Accessories:
The TRN comes in a small white box typical of of TRN's latest offerings. Accessories are pretty bare bones with 3 sets of silicone tips and a detachable 2 pin QDC style cable. The included black braided 4 core cable has metal plugs, inline microphone, and splitter, while the 2 pin housing is plastic. The cable also has preformed ear hooks.
Build Quality:
Build quality is very good with an all metal shell made from aluminum or magnesium alloy according to the product listing. The nozzle, however, is made of plastic and has a lip to secure ear tips. The finish is a little rough in certain areas and not completely uniform between the left and right shells. There is a metal grill covering the small opening at the center of the faceplate with a single trox screw located at the lower tip of the faceplate. The screw looks to be cosmetic only.
Fit and Comfort:
The smooth sculpted shells provide good comfort for extended listening. Although I found the shells a little bulky, I did not notice any pinching or sharp edges during listening. For me, the IEMs did not fit as securely as I would have liked possibly due to the bulk and shallow insertion depth. Sound isolation is average. There is noticeably more sound leakage in the BA5 due to the open vent design.
Sound Quality:
The bass is fast, tight, and controlled, but lacks the sheer quantity and rumble that bassheads would desire. The strengths and weaknesses of BA bass vs dynamic bass is apparent here. You are trading impact and power for more precision and detail.
Mids are more forward sounding and less recessed compared to many budget offerings in this price range. Mids are clean sounding but have good body so they don't sound thin. There is also good detail and resolution in the midrange.
The treble is well extended with good detail and crispness. There is nice airiness in the upper registers without any shrillness or sibilance.
The soundstage is large with excellent instrument separation which provides good cohesiveness between the musical elements and prevents complex tracks from sounding congested.
Conclusion:
The BA5 is a very well put together IEM. Good build quality, excellent tuning and great sound quality. These are a recommended get for those who like BA bass with smooth, clean mids, and bright airy trebles with superb soundstage.
