R4 mp3 & mp4 Players spotify Player with Bluetooth and WiFi 4-Way HiFi DAP Android 12 OS 3.5mm po+4.4mm bal 32G+2TB Scalable Memory

I bought this principally because I was going to have a time in hospital where wireless earphones would be impractical due to their limited battery life. the HyBy filled the brief having excellent battery life and provision for charging through USB as it plays. However, it was an excellent buy in so many other ways. It has no right to be so well built or sound so good for the money. It is significantly better than my 4-year-old IFI Hip Dac, Which is just a DAC. With all its many streaming features, the HyBy cost only slightly more! It uses Android, so one can use whatever apps you like, but the HyBy Music Player also has a 'Pure Mode' which bypasses the limitations for playing back high-res music built into Android. One can access. For example, one can access QOBUZ this way and it sounds excellent. There are also various equaliser options. There is a fancy custom one - I have forgotten the name of - which degrades the sound to my ears, but the parametric equaliser works excellently and has enabled me to tune the sound to my hearing and headphones very precisely. The headphone amplifier which can be used either single-endedly or in balanced form is surprisingly powerful and very good at conveying the dynamics of music. Although they are not an especially difficult load compared with some others, my £450 or so Grado RX2x headphones were driven well enough to give of the considerable best. The sound has very neutral tonality, very good dynamics as noted, and has a surprising amount of 'space' around it though this aspect of the sound is bettered when using the same headphones through my very much more expensive HiFi DAC and valve headphone amplifier. What is more the HyBy is not a bad streaming transport when used with the HiFi separates' DAC. It's even better when fed through my inexpensive SMSL gizmo which cleans up the signal using a better digital clock. All in all, quite a bargain!

I have a Fiio M11S that I manged to bounce off the foot of my chair and crack the screen. I sent that to China for repair and sat without a music player. Then I bought an M300 which couldn't drive my cans. I sold that and bought this. It is good. It is also nicely styled IMO. I bought a separate strap which is also v good. The MSEB equaliser is beyond me but is very capable. It sounds quite neutral and I can't quite get the bass to where I like it. I would recommend it but...my music is on a separate sd card for convenience although I write to it though usb typically. From fiio to hiby no issue. From hiby to fiio however there appears to be some incompatibility in file format. Even though they look the same, neither the fiio nor my laptop can see anything written to the sd card whilst it was mounted in the R4. I had to delete the files in the R4 then rewrite the to the sd card from my laptop. So. Yeah. That's a thing.

Great DAP with a nice sound (I typically play around the 35 volume level) and has enough processing power to play streaming audio unlike the R5 which will give up. My only complaint is how warm the device gets to the point where I avoid using the balanced output. Single ended seems okay though. Shorter battery life compared to the R5 but good enough. It's an Android device so you can install things like Amazon Music and Youtube Music and stream audio which is nice.

I bought this for my son as he’s just getting into music and at 11 years old we were having the debate about getting a phone or something more dedicated to music. We opted for the latter and the hiby R4 came out top in most research for good quality entry DAPs. I’d already ordered when I was chatting to my neighbour who is a big audiophile. He told me not to order a DAP just yet. When I told him I’d already ordered an R4 he breathed a sigh of relief - he was going to demo his as proof of it being worth the price. Suffice to say when it arrived we weren’t disappointed. Songs I’d listened to for 30/40 years all of a sudden had new layers, new textures and were transformed. And this was on a pair of cheap wired Mario switch themed headphones. My son now has a fantastic music player but he can also have some elements of a smartphone such as clock / alarm / calendar and some streaming apps - but none of the toxic social media. Suffice to say one of these is now on my Christmas list.

Great sound and operation is smooth. Feels solid and looks great too. Plenty of power to handle all my IEMs with room to spare. Nice screen. Decent enough battery life for my needs.

Arrived in brand new condition, unboxing was a good experience. The Hiby looked absolutely great but wouldn’t turn on, blue screen, got in touch with support, still couldn’t get it started. Very disappointing for a main Xmas present to not even turn on. Reviews on other searches show this issue is happening quite a lot. Returned it but having to wait for all of my money back for a few weeks. Which I think is totally unacceptable. Turned into a very expensive brick for Xmas.

great dap and good quality sound but poor apps and does not manage multiple cd indexing which i need for classical music. You can insert a micro sd card. I went mad and bought and inserted 2 TB. This did work, but i had to put the card in the other way up from what the manual said. Insert with contacts of the micro sd card FACING up. Well perhaps mine is an odd one that has been manufactured badly!

I must have bought nearly a dozen different mp3 players over the years. Finally one that not only gets the hardware right but also the software. Some of the older tracks I've listened to are like hearing them for the first time. More importantly almost is the ease of using the interface. So often a let down on cheaper players this 73 year old managed to access all aspects with ease - navigating swiftly through the layers. My only request on future releases would be a consistent 'back' button but that's a really minor niggle. Top tip: rip to FLAC for best results.

Aprender a usar todos os seu recursos demanda certo tempo, mas vale o esforço. Robusto, moderno, completo para os audiófilos que querem excelência sonora.

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.

Absolutely adore this player! Coming off a Hidizs AP80 Pro which is still working very well, the Hiby R4 is still a considerable improvement! I have a large personal library (about 14k tracks and growing, across MP3, AAC, WAV and FLAC formats) and being able to free up thay space from my phone to listen without having to connect to Wi-flDi is incredible. Paired with my Sennheiser HD 660S2 headphones, it's and been such a joy to use during work. I've used it pretry much every day since it arrived!

Muy contento con el desempeño el audio es mas nítido y con el equalizador suma mucho el sonido mejora aún mas con audiofonos de cable, principalmente lo compre para usarlo específicamente para música y podcast y que se conecte a mi auto , de manera que las notificaciones del celular no esten molestando a la hora de escuchar música super recomendado

Very nice. Everything working great. Only wish it had better battery life but charging is always close by.
