F20 HiFi MP3 Player with Bluetooth5.2, Lossless DSD High Resolution Digital Audio Music Player, High-Res Portable Audio Player with 64GB Memory Card, Support up to 256GB

It is amazing all of the advances over the years have allowed such a genius system for under $200. I still buy compact disc for a good home stereo, even though I know I could have switched to all USB/Tf. But I have so many CD's from when I was in high school and I converted all of my most favorite songs to .WAV, and I am aware this can also play .MP3. I believe I may have a little more lossless audio with .WAV. Connected to 2 paired speakers of the release of "DOSS Waterproof Bluetooth Speaker with Big Sound," I have easy wireless stereo. I could have bought better speakers but I needed everything to fit in pants and or shirt pockets. Thank you. I did convert CD music as well as rip some YouTube videos, and I end up having to convert .mp4 to .wav, or .wmv to .wav, or if all I have is a .mp3 song I guess I don't need to convert it but I still do some like DJ edit and convert it to .wav again. I did not have any connection loss through the entire time I was riding the Ebike when I keep the speakers near the music player. I had to buy this system or some system, because I was attracted to pairing speakers and it only works with a Bluetooth transmitter. My speakers work with TF card but cannot pair 2 speakers without this lovely Surfans F20 or other Bluetooth transmitter. I know I got my money worth out of this. You all could just accept that this is an inexpensive portable system, and it is good, but it has limits. I did a lot of leveling myself with many songs in Sony Vegas Pro and Sound Blaster Creative WaveStudio, so I can just play my songs "as is," preloaded with my effects. I'm not going to bs. There is more than enough high tech features with Surfans, but not as incredible bass as my more costly super power movie pc and its extreme sound card, with the big bass headphones. Honesty, for deep rich bass to be heard in a wide open public space, it requires larger speakers, and nothing I can carry in my pocket, and I never intended to use this with headphones. I can be low key with the Surfans player and the small speakers I got. Now I might try to test out better speakers in the future, but I don't need it because I have big home speakers and I would get a big bumping car stereo if I had the time, although I would like to lock any car subwoofer down so I can race the car without it shifting. I like to be extreme and on the edge. I'm not going to lie. I couldn't find any Bose bluetooth pairing speakers on Amazon until after I bought a pair of DOSS, but with my extreme desires, I would find a way to be unhappy with small Bose speakers. This product is worth it because the cost is fair and it is very advanced. When all is said and done, all I wanted was something that would play music and did not want to pay more for a chance for anything better currently. There are ways this system might be able to get better sound but I'm not going to bother to try to attach sound reprocessing hardware. Anything might be possible in theory. I like how small Surfans is. I attach my little speakers to my clothing and avoid using headphones. I fit Surfans in my pocket. I have listened to my waltz mix while plugging the big home receiver into the little music player through the headphone port as if it was an AUX port, and it sounded fine. I have large Bose Stereo speakers in my room but no current connected subwoofer because it was damaged. Surfans F20 is not bad. It is everything that I thought it would be and more. I could even use this to put on a table in any room where there is no speakers and use my little easy to move speakers, or humble myself to using some headphones and use it like a walkman. I don't want to discredit how good a $30 speaker can be, because nobody is paying much money to start with. Songs can be edited with audio software to maximize a particular music player and or speaker's sound quality and max volume, and it can sound more fine tuned with no distortion, and it can help me not have to adjust EQ and Volume from one song to the next. It is a lot of work but I am doing that and as a tribute to this music player. I am making remixes of many songs I have never worked on before, so I can celebrate what I think is good music and is a lot of lovable songs where people play either electric, acoustic, and other instruments, and really sing. I really don't care what people think about me. Some singers have a great voice and I enjoy hearing it loud. Nobody cares what kind of speakers I have. What matters more is that I have good sweet songs that can be heard alone, and or by anyone to share it with. I sold my Oldsmobile and sold one sub to somebody and then used one in my room until I accidentally fried it. What I like about this Surfans music player is how I can continually listen to music while traveling and while each song is in an editing process, without having to waste recordable discs. I can write 24bit music or maybe 32bit, to 48hz & 44hz better sound files, but I'm not sure if this system can play higher than 44hz/24bit/32bit, or if it would downscale it from 48hz to 44hz? It had no trouble smoothly playing my 24bit 48hz (.wav) compilation I've recently been making of a beautiful waltz, march, and sweet sound replays; it's an extremely edited mix, preserving the original songs in the classical characteristic, adjusting paces to maximize dance potential. It is symphony and orchestra as well as instrument people doing nice covers of those things. It has all the wonderful human manual instruments including drum, piano, brass, and strings. This assembly song takes up over 424 Megabytes and is 25m&46s length long. Most songs I saved as 44hz 16bit stereo. The battery does last a long time. I can enjoy the no gap feature of the music player and write the audio like it is in dvd chapters or can render it as whole whole piece. As of 9/17/24 I have created multiple folders of songs and I inserted myself singing too in one of those folders, with certain good songs, and it is fun and seems real if I get a good voice recorded not only because that is sweet, but because I can find songs where any person(s) do instrument backgrounds with no singer and then I can be the one to sing it; it is beautiful knowing that I didn't do all of it myself even though I can play the piano. I don't have a good piano at home and that sucks when I want to record. I have a keyboard that has had some technical problem lately but it is pretty good and it cost way more than the piano my parents bought. I also have my own style and other people have different style. I've never thought about pressing the same key over and over again when I cover music, but the way one woman does it I swear it is absolutely gorgeous. She covers rock songs.

PROS- Fairly low cost (especially during Black Friday, when I got mine for a little less than $100.)- Solid, heavy build- Metal body- Glass screen and back- Physical buttons- Screen lock- Expandable storage- USB-C connection* (others have said it is micro USB but I believe they have switched to USB-C for new units.)- Built in EQ, with presets* (I don't find the presets to be amazing, but they aren't absolutely horrible.)- Bluetooth 5.2 (I have not tested this; I use cheaper HQ wired over ear headphones - DT 770 PRO 32ohm.)- No hiss* (others have reported a hiss, but I have not expirenced this at all, however I am mildly hard of hearing and possibly use high enough ohm headphones to mitigate it.)- Separate audio out* (supposably unable to be used simultaneously, not tested.)- On-The-Go capability* (unfortunately needs a USB-C specific drive or a dongle; no full sized USB port. Untested.)- High or Low Gain- Replay Gain settings- Balance Settings- Shows album covers- Lyric capabilities- Gapless playback- Album playthrough- Different language settings- Remade theme selection- Backlit, with settings- External DAC setting for streaming or playing music not on the DAP- Font size selection- Shows remaing memory- Browse by category or file explorer- Good battery life- Recently played songs list- Favorites can be selected on the DAP- Headphone jack on bottom of DAP to more easily fit in pocket- No finicky, fragile touch screens that are hard to replace and die quickly- Can be easily used with gloves- Gold plated contacts- Plug and Play- No DRMCONS- The UI, while still definitely is usable, is clunky and takes getting used to- Playlists cannot be made on the DAP and must be made on a PC with a clunky 3rd party software- Indeapth instructions are not provided for the 3rd party playlist software- Playlist are not support with all formats compatible with the DAP. I spent multiple hours trying to get .opus files to work as a playlist but was ultimately unsuccessful and had to us .mp3 files.- You are unable to use playlists you make in other programs- The screen is fairly low resolution- The screen is not large enough to display the whole album cover with the UI design. It cuts off a small portion of the art.- The texture on the scroll wheel should be increased to combat the lack of friction- The micro SD card slot is very deep and I am unable to get it out without the use of a tool- The back glass is very prone to getting grease and finger prints on it- Edges should be a bit more rounded; not amazing to hold and hard to slip into a pocket- I don't find the back very attractive- While I don't dislike the metallic slate grey color it comes in, other choices would be niceOverall, fairly happy with my purchase and think it is a solid entry choice
