The FiiO headphone amp is a pretty interesting device despite not looking like much at first glance. Most people will probably even think that this is a crap device, but hear me out for a moment. Apparently, the FiiO amp offers some pretty decent audio quality, and being slightly larger than the AAA battery that powers it, the portability it another big plus in my books. At a mere $8.50 a pop, this low price would seal the deal for me. If you’re one who listens to most of your music through a pair of headphones, then getting the FiiO headphone amp sounds like the logical step to take before you upgrade to a more powerful pair.
