Okay, let's talk about this little music player that's been driving me crazy in the best and worst ways possible.

First off - the sound quality? Absolutely BONKERS good for something this size. That CS43131 chip is no joke, and playing DSD files feels like I'm rediscovering my music collection. The Bluetooth 5.1 works surprisingly well with my fancy headphones too.

BUT (and it's a big but) - the interface feels like it was designed by aliens who've never used a touchscreen before. Want to connect to WiFi? Prepare for the most frustrating password entry experience of your life. It's like texting on a 2005 flip phone all over again.

Pro tip I discovered: You CAN actually add whole albums to playlists! Took me weeks to figure this out because THERE'S NO MANUAL. Seriously HiBy, what were you thinking? I've had to become some sort of digital audio detective just to use basic features.

The expandable storage is awesome though - popped in a 512GB microSD and now I'm walking around with my entire music library in my pocket. The battery life is decent too, though not quite the 15 hours they claim unless you keep the screen off.

Final verdict? When it works, it's magical. When it doesn't, you'll want to throw it against a wall. Here's hoping HiBy keeps updating the firmware to fix the quirks. 3.5/5 stars (would be 5 with a proper manual and less janky UI).
