I have a Fosi Audio K5 Pro Gaming DAC Headphone Amplifier which is excellent and use this for watching TV (via TosLink). But wanted a remote control to adjust from afar so got this. Excellent sound as well once tweeked with the bass / treble. very happy

First I would like to say that I have a much more pricey Topping D50s DAC which I have connected up to my desktop computer fed into a Pioneer SX-850 receiver with Triangle Broea BR03 speakers. That is a great audio set-up giving great sound. So I know what a decent audio system should sound like and the MUCH cheaper Nobsound Q4 Mini can really hold it own. It's hooked up to a Scott 477 receiver into reconditioned AR2ax speakers. I did the reconditioning... rebuilt crossovers, and replaced destroyed woofers... made these work great. Anyway the result using this Q4 Mini was a very good experience. I also liked the addition of having the extra bass and treble adjustments... fine tuning the sound. SO, I would recommend this DAC much more than I thought I would.

This amps takes everything. From working as a dac for computer, USB tumbdrive, bluetooth, optical, and coax.You can control USB thumbdrive mp3 files with remote - change track, type in number to jump to that track (although you cannot see which track is what number, but you probably has some idea which song is around what track number). Runs cool. Look so cute. Bass sound is awesome out of this dac.This little tiny dac is way better than one that costed me about 4x more (that dac had almost same function as this little guy but broke within 6 months).Love it and highly recommend.

Quick update to the review, still four stars, but I find one thing very annoying and perhaps the manufacturer will see this and fix it with a firmware update. The issue is once my BLE source is lost such as when the phone leaves the room, the blue "BLE" light continuously flashes. It is annoying. How about just shutting it down after 10 minutes of inactivity? That would be much better.Original review:I did a comparison with standard BT and this unit which claims a special 4.0 BT. The range was definitely better, perhaps 2x the range with solid performance. Using Spotify it's difficult to tell, but the audio did sound better than direct streaming from my iPhone and I will attribute that to a superior DAC in this unit. However, the accompanying materials do not provide specifics on DAC performance/composition.I could not get the TOSlink to work. This could be my amp as I have yet to try it, but the supplied cable was difficult to connect on the device and on the amp. I suspect the cable.The supplied USB cable was actually very nice and sparkly blue - not just the standard black you might expect.My biggest complaint is the bass/treble control on the unit and the supplied remote. If you want to upgrade your audio by using this external DAC, that puts the user in a category that he/she will already have tone control elsewhere and more apt to use an app than physical remote. We are overrun with too many remotes. A quality app that does these functions (on/off, source select, output select, volume) should replace the remote.My last complaint is the system is 5V via USB-C, but no power supply is included and the cable is short (1/2 meter?). I think this is a near-miss to a very nice little DAC

Got this DAC because I have the Prozor equivalent, which works well with one drawback. When connected to TV via optical, you need, as is usual, to use the volume on the DAC remote. The Prozor volume control is terrible - it virtually has only 3 levels - off, moderately loud, and deafening. I was hoping that this was better, and it is. This Nobsound DAC seems a little better made with some extra controls and it's remote has full functionality. As for sound, I maybe can't hear what some audiophiles are convinced they can hear, but both the Prozor and this Nobsound sound excellent to me - both via optical and Bluetooth input. I have the DAC wired to two active beolab 4000 speakers. I'm very pleased.
