3 source(s) feeding this product's score.
Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
13:56The reviewer finds the TRN BA15 to be a surprisingly successful flagship multi-BA earphone, with a V-shaped but comfortable tuning, excellent build and accessories, and natural-sounding highs. However, it has a dry, neutral bass lacking depth, a recessed lower midrange, and can sound harsh on heavy or poorly recorded material. Overall, it's a positive recommendation for its price, especially for calm genres.
21:43The reviewer finds the TRN BA15 to be a well-built and comfortable earphone with a balanced, detailed sound that excels with acoustic music and well-recorded tracks, though it lacks a bit of weight in the lower mids and may not satisfy bass-heavy genres. The treble is improved over the BA8, being less bright and more comfortable, and the overall presentation is engaging with a good soundstage.
