Hi from Spain.

I usually listen music with my Bose QC15 connected to iPhone 4 (when I'm walking) or connected to MacBook Pro 2012 ( when I'm working).

I just wonder if I could improve its sound using FiiO E17 or another headphone amplifier.

Could you please me help me?

Thank you.

The QC15's are already amplified by their internal circuitery and you won't get any benefits from using a headphone amplifier with them. You could use the E17 as a DAC with your Macbook, though.
