Location of USB and audio terminals
The 5K comes with a 3.5mm audio terminal at the top and a usb-c terminal at the bottom. However, this design can cause many problems in actual use.

If 5K is secured to the waist and used, the risk of cable break increases because the cable near the earphone plug bends downwards.

The second problem occurs when using USB DAC mode. When the usb-c terminal is located below, the machine is usually placed upside down when connecting to a PC.

This does not cause use problems, but it is not a very convenient way.

Of course, this is not to say that we need to solve these problems right now. 5K may not be the last product of qudelix.

If my idea can be seriously considered for the upcoming product, I will continue to be a loyal customer.

Finally, we sincerely hope that 5K will hit the market soon.
