Surfans F20 HiFi MP3 Player with Bluetooth, Lossless DSD High Resolution Digital Audio Music Player, High-Res Portable Audio Player with 32GB Memory Card, Support up to 256GB

This Bluetooth MP3 player has amazing sound quality and supports many lossless music formats. It connects easily with Bluetooth headphones or phones and works both ways. The screen and scroll wheel make it easy to use, and the metal body feels strong and nice to hold. It also has long battery life and storage for thousands of songs

I have been using this device for a few days as an audio player (not a USB DAC) and I can tell you the following:The Bad:1. The software is very simple, you won't be changing any wallpapers or any fun stuff like that, it's designed to simply play audio, kinda like the old MP3 players.2. The bluetooth on the device isn't great, I had a pair of bluetooth headphones connected to it and it would have this issue where the audio would rhythmically cut out, it is fixed after restarting both devices, and it shouldn't happen, but it does and it is fixable with a restart of both devices. (In my experience)3. The software in "Category" (Music symbol in menu) reads the files to determine which folder the audio should be in, so if you are trying to organise your music via folders etc on your computer, it isn't going to work unless you are using the "explorer" function instead. (Folder symbol) However, this works fine but was a little confusing at the start.4. The scroll wheel does take some getting used to, it's not haptic like the old Ipods, it's a physical wheel you have to turn.The Good:1. It can play almost any audio file you put in it.2. It does support lossless audio files such as wav and it does play them pretty well.3. It does have memory play, so if you pause the music due to being busy, it will pick up the last song you played and you can even change it to remember the exact position of the song you were listening to at the time. (Can be changed in settings)4. The "M" button on the device is a multifunction button, while in a song you can add / remove a song from favourites, edit the EQ, edit the play mode etc. In the "explorer" and "Category" menus it allows you to delete files and add the song to a playlist.Overall it's a simple device that has the ability to play high quality audio. This obviously depends on the headphones you're using and the audio format you're trying to use. If you're using a basic MP3 file with £20 bluetooth earbuds from an unknown manufacturer, the audio isn't going to sound very great and you're not going to have a fulfilling experience.On the other hand, if you're playing Wav files which are uncompressed and have some good quality wired headphones, you're going to have a much better listening experience.I do recommend going through both the "settings" and "system settings" for the device and playing around to see what suits you.P.S If you're having issues with the music not syncing from the card, make sure "Music Sync" is set to automatic in settings, then remove the card and put it back in.

I bought the mp3 to listen to music and also use it as a DAC to improve the sound quality of my computer. The latter is the main reason I bought this. The battery life is good and can last for a while once it is fully charged. It is easy to connect to my Bluetooth speaker when I want to listen to music while working in the garden. The sound quality is better than my mobile phone, when comparing using the same Bluetooth headphone. The functionality of the mp3 is relatively limited as this is not an Android device. It can only play music. The speed is fast when playing and switching music. For the sound quality, I think it is good value. Of course, there are better mp3 players available, but they generally cost more.

DO NOT BUY - this was a great little player when it worked but it ddint work for long! Within 2 months the power button would not work, so the only way to turn the machine on or off was by plugging a cable into it, and now after 4 months even that will not work, and it is now only usable as a paperweight

The build quality is far superior to a lot of all plastic players, it is I understand machined from a solid block of aluminium and coated with a finger print resistant protection. Easy to operate once the manual is downloaded and printed out in a readable size. Somewhat difficult to read in bright sunlight due to reflective screen and small print size, the print has 3 size options, all are small, the smallest being minute. The screen can be given a longer time delay, this can be achived in the settings section Sound quality is excellent. Volume can be a problem using bluetooth to a set of headphones, volume can be very low, yet with a pair of cheap wired Sony headphones the volume was fine, so I tend to think the headphones might be the problem. There is a gain option which gives a certain amount of volume increase. All in all a first class player which notwithstanding the price is worth it and it is a very presentable package.
