18.Is it worth it to have such a high output power of KA13?

In fact, most headphones require high enough output power in order to get better sound quality. According to our experience and market feedback, the "desktop mode" of M17/Q7/M15S and other portable products have been recognized and welcomed by our users.

So this is the reason why we introduced the "Desktop Mode"with higher out power for KA13. Of course, "desktop mode" does not mean that it has all the performance of desktop devices.
