Fiio E5 Headphone Amplifier Review

This isn’t my Cowon S9 32GB review. You’ve probably noticed that from the title. It was meant to be though. I just haven’t finished that yet. Along the way though I picked up Fiio’s wonderful little E5 headphone amplifier and I thought I’d post this mini review to tell you all about it.

But first, why on earth would you need an amplifier for your MP31 player?

There are several reasons. Firstly the headphone amp in many personal music players is cheap, nasty and the last thing on the mind of the designers of what might be otherwise an excellent quality PMP. Some lack power, meaning that even on small headphones you have to crank up the volume to hear in a noisy location but the result is distorted sound. Also small rechargeable personal music players – even the very good ones – aren’t designed to be able to power massive audiophile headphones with an impedance of 300ohms.
