Received my Q1 and its working without any issues with my OP3T and amazon basic USB-c to micro-USB cable. All of the system sounds are routed through the DAC when attached. So, I can play Soundcloud, youtube, podcasts app, any music app etc. I use poweramp alpha build 704 with USB DAC support...

Have you used it with any android phone? How is the SQ?

Hello, Any SMSL X4 user here ? Does that DAC also has these same buzzing issue ?

Cool ! Will sure look into this DAC.

That I know. I was talking about general reliability . Do you have the X4 ? Are there any EMI/RF Interference issue with it ? How will you describe the sound quality,loudness and compatibility with smartphones?

Yup but also here in headfi. Like here https://www.head-fi.org/threads/do-not-buy-smsl-products-specially-smsl-m2-usb-dac.753399/. I also saw few users in aliexpress complaining about a humming noise and things like that.

Thank you. Sabaj DA3 is little out of my budget. And about SMSL I have read about lots of complaints on hissing , popping sound and reliability issues.

Thank You. I will look into this DAC.

Because I couldn't find the Black 1.5 i.e. the new one compatible with mobile phones in India. And most of the second-hand ones don't ship to India. Also, I heard DF Black suffers from low volume issue.

Hello , I want to improve the audio of my OP3T. Can anybody suggest some good DAC/Amps in the range of 70-80 USD? I was looking at Fiio Q1 and HiFiMe Sabre 9018 USB Type C. The price of both of them is same. Can anybody suggest another DAC/Amp?

Thank You. I actually searched but couldn't find any clear answer. I found a cable btw. Here is the link https://www.amazon.com/dp/B01LONQBDG/ref=twister_B06WGQMXYX?_encoding=UTF8&psc=1.

Thank you. By any chance, any guess what will happen with 4G VoLTE?

Hello, Can anybody please tell me if Fiio Q1 supports OnePlus 3T for DAC functionality? Has anyone tried?

Can you please clarify a bit? Do you want to mean there is RFI/EMI but reduces when using 3G?

But it is also likely to be suffering from the same EMI/RFI issue.
