Where you bought it? Amazon?

this happened to me too at the first time. It was later fixed

Change 2KΩ to 1KΩ value

The modified amp module has arrived. There was dead silence! Thanks xduoo! by replacing the resistors, the sound image changed positively. The 3d sound goes deeper and more dynamic.

Has anyone tested this opa1622 op amp? Won't the resistors and custom circuit damage the xd05 pro device? I tested it and it makes a soft popping noise during play/stop. It has a warm, mellow sound and wider than opa1612.

Yes, of course.

I can thank the Amazon seller that the xduoo service responded to the problem. After that, I kept in touch with the xduoo service by email.

Yes, The xduoo engineer promised to send a modified module (with a different resistor). This price: 20usd

Hi everybody! My package was delivered by the xduoo service today. For white noise, I get an amp module that the service modified. Price: 20usd

Electric, ticking, crackling noise. This is normal, it was also present with topping g5. Then you also have volume control inaccuracy. :)

If I turn the volume control slowly or quickly, doesn’t matter.

Thank you!

The digital volume knob sometimes moves 2 steps forward. Anyone else experiencing this?

I don’t experience different charging options.
