Nobsound Q4 USB Audio Gaming DAC Converter Adapter Mini Bluetooth Headphone Amp Amplifier for PC, PS5, Computer with Optical Input 24-Bit 192 KHz & Treble Bass Control & Remote

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

Not enough volume for my listening tastes. Easy to set-up and probably good enough for many. Not good enough to drive any of my good, audiophile headphones. I will probably not even use it.

The media could not be loaded. I’ve been using a high end upsampling DAC in our stereo system for years and while it sounds great I always wished it had a remote control. This little DAC sounds great and has a remote volume control that allows very fine increments of volume control adjustment which I love. This has just about everything you would want in a digital preamp, lots of inputs including Bluetooth, RCA & headphone outputs, and volume, bass, and treble controls too. This is powered by an USB-C jack and includes a cable but no wall adapter. Recommended!

Very finicky. Connect when it wants to. Most of the time it doesn't want to. Going to return and get something more reliable.

The converter is a good device to control. The converter comes with a remote control that is easy to use. The Bluetooth is a good feature. The converter allows you to control the bass and tremble. The converter is a good value and I would recommend it for the ease of use and the quality

I liked the price and the good sound coming out while connecting my CD player via coaxial cable. The only problem that I had and the reason for the return is that the Bluetooth disconnected from my phone for no reason very often.
