SURFANS F20 Benutzerhandbuch Seite 11

If your headphones are Bluetooth and have volume adjusting button, then yes.
9. Can this player work with iTunes? Is it compatible?
No, unfortunately, it is doesn't compatible with iTunes. This functions more like an external
hard drier. You simply plug it in, an option to open it as a folder pops up, and you simply drag
and drop your music.

15. When would you adjust the gain setting rather than volume?
I have my gain setting on high and use the volume to control the audio output from aero to
max. High setting gives you a higher output. I think the gain setting is to adjust for different
headphones used with this player. Headphone impedance can range from 8 ohms to 64 ohms.
The 8 ohms would be louder at the same gain setting as 64 ohms.
