HIDIZS S9 HiRes Headphone Amplifier HiFi Decoding USB TYPE C DAC to 3.5&2.5MM adapter DAC Amp for Phones/PC Portable Audio out and the Hidizs LT01 lightning to Type C transfer cable. I bought this in March 2021 from AliExpress (S9) for $94.71 with Tax and the iPhone adapter from HiFiGo for $30.99. It works perfectly on my computer and iPhone. The sound quality is much better than the MacMini internal headphone output and the quality is great on the iPhone too, but I can't tell the difference between this and the Apple Dongle, and I got this for mobile use only. So it cost me over $125 but it is yours for $95 and I'll pay shipping costs. PM me if you are interested. All original boxes and papers included. Thanks!
