Okay, so I've been using the HiBy R6III for a solid month now, and wow - this thing is a BEAST. Let me break it down for you:

First off, the sound quality? Insane. Like 'forget-your-surroundings-and-just-vibe' good. The dual Class A/AB amp setup makes my high-impedance IEMs sing in ways my phone never could.

The Android 12 system is buttery smooth - no lag when switching between Tidal, Qobuz, and my local FLAC files. Though fair warning: getting Google Play set up was a minor nightmare with all their security hoops.

That MSEB equalizer though? Game changer. Spent hours tweaking settings to get that perfect sound signature for my collection. The spatial audio plugins make some tracks feel like I'm in the recording studio.

Build quality is premium - all glass and metal, though it does get warm in Class A mode (worth it for that sweet analog-like sound). Battery lasts me through full workdays unless I'm blasting high gain all day.

Only real complaint? Headphone jacks at the bottom instead of top makes pocket use awkward. But for $600? This punches way above its weight class compared to $1k+ DAPs I've tried.

Final verdict: If you're serious about portable audio but don't want to sell a kidney, this might be your endgame player.
