HiBy R4 MP3 MP4 Players Spotify Player with Bluetooth and WiFi 4-Way HiFi DAP Android 12 OS 3

Excellent for working out. Great sound easy to use and intuitive once you spend some time understanding how. It helped that I set it up for the person I gave it to and then walked them through how to use it. Great sound and holds lots of tunes. Easy to just take your micro sd from one device and put in this one and then set up your songs the way you want. Great price for what you get and looks cool too. Battery life is pretty good and it looks very durable-no complaints from someone who uses it during workouts. Buttons make working it easy and the screen is big enough to make it easy to see and read while using. Pretty fast interface. Read more

GREAT product! Downloaded 200GB+ FLAC files and at least 50GB of Spotify music to 1TB microSD over Wifi using SyncThing and Spotify, drained battery by 45%. This is incredible. Took a nap while it finished downloading a couple dozen GB of FLAC files on the charger, was cool to the touch and fully charged when i woke up several hours later. Spotify CANNOT be used while downloading files to microSD card, nearly unusable, even on a high speed card. The music i listen to all the time (using bluetooth, Spotify, Very High) is noticeably enhanced. I have not tested with wired headphones yet, but I assume the enhancement would be even higher. Connects and works well with both my vehicles bluetooth systems (Microsoft Sync and Generic GMC). Today it was 96 degrees F and downloading both Spotify and SyncThing/FLAC at the same time produced noticeable heat, but not much more than my phone while browsing facebook. The system is blinding fast and reacts to button presses immediately. The bit perfect system is very apparent. Very easy to use. I really can't find a reason to complain about this device. Besides maybe not having a GPS chip so I could use it entirely instead of connecting my phone when i need to get directions. But that is not the point of this device. I like the color better with the TPU case on and the warmth of the device when syncing so much data, at the same time, in nearly 100 degree weather would have been a bit much to comfortably hold the device for a sustained period of time. Storage capacity is adequate for testing the device, but you will want to use a microSD card formatted in exFAT format (mine came preformatted). I got the green one, and instead of the neon green, with the TPU case on, it is more of a forest green. I was between this and the M300, and the battery life is worth not having an onboard speaker. Body is aluminum and glass, very high quality and durable build quality. Read more

Musically this thing sound fantastic with midrange headphones. My MAC MINI does not recognize it though so I had to put the SD card in the MAC MINI accessory and transfer files that way rather than over USB. Oh, the other thing is that it boots slow and shuts down slow by today's standards. Read more

This Device is great if you want to listen to music offline. There is a lost of settings and customization within this device that takes a while to get used to but works well. The option to expand the storage is a plus and easy to access within the device when importing music. Connecting to bluetooth is easy to do and the sound quality is convenient but it does not compare to listening to it with wire headphones, there has been latency and skipping if I'm using bluetooth while I'm walking so keep that in mind while exercising. The touch screen is not very responsive at time compared to your usual smartphone but the physical buttons make up for it. The device itself is well made and sturdy as well. Overall this is a great modern Mp3 player/DAP for the price the pros overweighs the cons in my opinion. Read more

This is the pinnacle of media players. The sound is pure and powerful. Bass is punchy and clear. There are so many ways to tweak the sound, I doubt I will ever know the full capabilities of this player but I know I won't be looking for another one for a long time. The player is robust and well made. UPDATE!!!! it's a brick. Woke up this morning and went to turn it on and nothing. Plug it in to USB and it shows the Hiby logo then the battery power is at 100% then...nothing. Tried every trick in their book and online and absolutely nothing worked. It's a brick. Don't waste your time. Update #2 it's costing me $40 just to send it to China. Not happy at all. Read more
