Hill Audio ALC4050. This dongle reminds me a lot of the JCally JM04Pro, another excellent Realtek ALC DAC implementation. It is very clean sounding with vibrant dynamics that even make my TIN HiFi P1 sound exciting and musical. Perhaps not as razor sharp with precision but then the silver lining of that is, very smooth presentation that will not induce fatigue for extended listening indulgence. A great deal of people will find this ALC4050 entertaining, me included. It is polished and mature in many ways, not attempting to overdo anything. This is one very modest dongle, and that modesty is its greatest appeal. Synergize great with many type of IEMs/Headphones up to 100Ω, but even better with technically competent BA or speedy DDs. In fact, I am liking this one better than JM04Pro because the JM04Pro may have some tendencies to exhibit some treble glare on shouty/peaky music. So personally, I will give extra points on that element.

⭐⭐⭐½ ($9.40)

Best Pairing: Technically adept IEMs/Headphones up to 100Ω
