Assuming you can get a proper fit, the Triple.fi 10 earphones will reward you with some stellar sound quality. This is thanks to the multitude of teeny, tiny tech Ultimate Ears has crammed into each earpiece. There are dual-balanced armatures for the low- and mid-range frequencies and a single precision-balanced armature for high frequencies. An integrated passive crossover connects each one to the individual speakers dedicated to each frequency. In layman's terms, this means you get tight, thumping bass; rich, encompassing mids; excellent detail; and sparkling highs.
