We recently got the chance to sample some great audio equipment thanks to the engineers at Trinity, a UK-based group that’s dedicated to bringing out the best from your favorite beats. Their DELTA in-ear headphones, designed with neodymium 8mm dynamic drivers and Trinity’s signature single balanced armatures, deliver high-quality sound in a tidy package. Three interchangeable filters allow you to customize your listening experience; the “fun” silver has a V shape signature for enhanced bass, “vivid” purple focuses on upper mids and treble – a feature that works well with anything acoustic – and the “smooth” gunmetal (our favorite) provides a natural balance across frequencies that makes any instrument or genre sound its best. The set also comes with three different types of rubber buds in a variety of sizes so you can find the best fit – though we found that nearly every option was extremely comfortable and even stayed in place during vigorous exercise, unlike most earbuds we’ve tried. And compared to typical headphones, Trinity DELTA cancel a fair amount of ambient noise that might otherwise distract from your tunes. On top of their functional considerations, Trinity incorporated stylish accents like a 1.2 meter multi-braid cable (which resembles a textile cord more than an electronic component) and an aluminum shell, which contributes both to great sound and good looks. The 24ct gold-plated 3.5mm Jack gives an even greater sense of their high-quality make and durability, while the optional angled fitting provides flexibility depending on the availability of a plug. It all comes wrapped in a simple zippered triangular case that alludes to Trinity’s namesake. Boasting 160 hm impedance, 110+/-3DB sensitivity, and 19-21000 HZ frequency response, these may be the most elegant, precise, and well-made sound system we’ve ever tried.
