Review: Low price high fidelity - Turns your phone into a first class audiophile streamer. Match with a good pair IEMs like the Truthear Crinicle Reds or the Hexa and you have a budget hifi that people spend thousands of pounds to achieve. I have both and I just love the sound.
Review: Ridiculously good sound quality for the price - I have to admit I've been on a quest to find one of these DAC/Amps that actually delivered on the hype. I've been through Moondrop/Fiio/Tanjem et all devices and I've found their Achilles heel sound quality wise. I want a device I can use whilst rowing, but also one that can power full-size headphones (some high impedance) as well as low impedance/high efficiency IEMs; I did initially give up and built my own Frankenstein setup comprising a Topping NX7 and a used Arcam rPac which I obtained from eBay and did a little refurbishment/maintenance on (re-soldered the input jacks as they inevitably succumb to the primary plug/unplug stresses). The sound of the NX7/rPack combination is particularly convincing (almost holographic, even for headphones) when connected to a pair of Quad ERA-1s, with fabulous dynamic and slam, where present. However the NX7/rPac combo is hardly something that could be worn on the belt whilst rowing and more lends itself as a travel DAC/Amp combo that one would take on holiday or on a business trip. Then I read about these in the esteemed New York Times (and also the usual FoTM ravings on YouTube) so purchased the with cynical view as to what I would hear. Well, surprise, surprise, whilst not having the transparency, refinement or outright slam of the Toppong/rPack, the Fosi presents a shockingly good rendition of the music presented to it and and is a good 70-80% of the Topping/rPac combo. So, I highly recommend this little device for serious listening with good headphones. One YouTuber mentioned this could replace a desktop amp/DAC to which my reaction at the time was "BS", but I think, at a pinch it probably could. I'm still going to use the Topping/rPac/Quad combo for travel/holidays, but for walking around town, or going to the gym, this little DAC/Amp, IMO, is as close to a true hi-fi experience you're going to get on the move (with the right headphones/IEMs of course).

### ⭐⭐⭐⭐ Decent for the price
*by H***B on 31 October 2025*

Good entry level DAC to get you into the streaming world. I paired this with a pair of Fostex T60RP and I was happy with the sound produced from it, I highly recommend using a 4.4mm balanced cable with this, the 3.5mm is far too quiet. The 4.4mm connection will drive your headphones much better, I wouldn't recommend this as a desktop setup, I would recommend something like the Ifi Dac V3 (yes more expensive but far better), however as a portable way to stream high quality music on the go I am happy with what I received and paid for and would recommend.
