Wireless charging?
Was there any discussion why this feature was not included? Bluetooth for me is all about convenience, wireless charging is high on that list for me. It would also have been a great hardware advantage over the Shanling UP4 and Fiio BTR 5. 

Is it possible you'll consider it for future products?

We've already checked the feasibility but made the decision not to support wireless charging due to the cost issue.
Anyway, we'll check it for the future roadmap.
Thank you!
