Just thought I would share a use for the above 3 pieces of hardware.
My Note 3 is streaming music from Google Play Music. The Note 3 is connected via USB , using its USB Audio digital out connection to the Fiio E18. The Fiio E18 translates the digital signal from the Note 3 and then amplifies the sound into my Sennheiser headphones.
The sound on the Fiio E18 is turned up just a little too loud and then using the Galaxy Gear I am now controlling the media and system volume up and down dependant on how loud or quite each track is. The Gear displays the song info as well.
A lovely setup. And incredible sound quality too.
