The FiiO A5 is the top model in FiiO’s A-series of headphone amplifiers. Nothing is left to chance to get better sound from your laptop, smartphone or tablet.. The FiiO A5 only inherited the successful opamp combo of it’s predecessor, but the entire circuit has been rebuilt, using better components. As a result, sound quality has gone up and noise and distortion have gone down. The FiiO A5 has no trouble driving the more complex load of high end headphones because of it’s selectable gain. It’s new, sturdy but lightweight housing is made from aluminium and comes in the colors black or titanium, and it has a newly designed volume control button. The rechargeable Lithium-Polymer battery gives you 13 hours of musical enjoyment, and a new ‘smart charge’ technology guarantees fast and safe charging under all circumstances. The bass boost equaliser adds more weight to the bass without muddying the rest of the frequency spectrum. Your choice in music is too valuable to settle for the standard sound quality of your laptop, smartphone or tablet.
