Hi, I've just bought a pair of TDK EB950. I first tried them directly on the MacBook Pro, and the volume was quite low. So I plugged them into the Fiio E10, like I do with my Akgs (IEM and headphone). It doesn't sound at all. I mean, something is audible, but it isn't certainly something I would call a sound. It's like they don't have enough power to work. I switched with the Akg k324p, and the problem disappeared. They sounded like they have always sounded.
 
 Akg: impedance 32 ohm, sensitivity 125 dB 
 TDK EB950: impedance 16 ohm, sensitivity 120 dB
 
I can't understand why. Help me please.
