The Fiio A1 is compact and simple, with a basic but functional design. It's small enough to fit in your palm, and has only the required buttons and ports. The casing of the amplifier is entirely metal, with a dull silver finish.There is a clear removable plastic strip along the top which can be replaced with one of the included belt-clip strips if you intend to keep the device clipped. There are three buttons on the top: one to control power and the equalizer setting, and two to adjust volume. Also on the top is the 3.5mm output for your headphones. The bottom has a port and a 3.5mm input, and you can use either of the two included auxiliary wires to connect the A1 to your source device. Also in the box is a standard USB Type-A to Micro-USB cable for charging. The listed 3.65dB gain can really be felt in use.
When the 'Bass 0' equaliser preset is used, it seems there's practically no change in the sonic signature whatsoever, just simply adding volume and improved sonic separation, imaging and clarity. 'Bass 1' boosts the sub-bass and mid-bass frequencies without affecting the top-end, which is an interesting tweak to the sonic signature for quick and exciting tracks. 'Bass 2' boosts sensitivity in the low-end, but forces a drop in the mid-range going up to the highs, while 'Bass 3' causes an equal sensitivity drop through the range.The last 2 settings are not to my taste but will appeal to some. The Fiio A1 is a simple device that does what it claims to do. It complements your headphones and source device by giving them a decent boost in sound, without messing with the sonic signature. You can play with the equalizer settings and tweak the sonics as well, but at its most basic level, this device is about improving volume and sound quality, which it does in a big way. The Fiio A1 represents tremendous value, and has the potential to improve sound quality no matter what kinds of headphones and source devices you use, and battery life is decent as well. All this on a budget.
