FiiO k11 R2R

Arrived in few days. Product is new and as described. Works and the price was the best in the region

FiiO K11 R2R - very good sound quality but with some issues.

The device is good quality and it sounds really great. But it has two issues. You cannot switch between L/R channels. It lowers both channels volume. The issue is mentioned on FiiO website. It has LineOut function, where device is playing on max volume and you can use your computer volume bar, but it is so loud that even on the lowest set it is screaming, so you have to choose another option and adjust volume on FiiO device instead. I wish I knew it before buying.
