The dac sounds very good, neutral and balanced. Love to listen to music. I use it with my iPhone SE 2022. There are two problems: 1. the cable between iPhone and dac has to be a special one, you need carefully chose an otg cable. 2. I did buy that cable in the shop of E1DA but it's very vulnerable when you use it during traveling and having the phone in you pocket. It's not special related to this product but making your audio portable by Phone, bend cable and dac.
