In this stream I unbox the Fiio BTR15 and do the real “first impressions” stuff: what’s in the box, how it feels in hand, and whether it makes sense versus my usual baseline—the Qudelix 5K. Mine arrived already opened (not by me), so I went straight into checking the physical side: weight, dimensions, buttons, clip, and that shiny glass-and-metal vibe. It looks sick, but it’s also a fingerprint magnet, and I was worried the screen might be acrylic—so yes, I literally scratch-tested it with a box cutter. Good news: it didn’t scratch like plastic, so it’s probably glass. I also compare size/portability with my other gear (5K, T71, Black Pearl), weigh them out (BTR15 around 36.8g vs 5K around 25.8g), and talk about why Bluetooth DAC/amps are actually convenient in real life—clip it, route the cable, and it’s basically “TWS with a wire.” I run through on-device menus like gain, filters, EQ presets, UAC 1.0/2.0 (useful for stuff like Switch/console controller setups), and I rant a bit about the Fiio Control app because… yeah, it needs fixing. After that, the plan is feature testing and a gaming test once everything’s behaving.
