HiBy R4
Universal Summary
The R4 is HiBy's $249 entry into real-Android DAPs: open Android 12 on a Snapdragon 665, quad ES9018C DACs with separated PCM and DSD pathways, and a Class-A analog stage. A spec sheet that simply did not exist at this price before it. Approved coverage from Headfonics and Headfonia agrees on the verdict: an excellent middle-of-the-road player whose software features and add-ons can raise its quality well above the sticker, with a slightly warm, musical Class-A flavor. The tradeoffs are equally consistent: a chunky, love-it-or-hate-it retro design, battery life that pays the Class-A tax, and technical performance that is good for $249 rather than good outright.
