FiiO A1 Portable Headphone Amp

The FiiO A1 Mini portable amplifier is an upgrade from the FiiO E6. FiiO has come a long way since the E6. While E6 had a simple and functional design, the A1 is most definitely a step up in overall quality and build. The A1 comes in an anodized aluminum chassis, which is both good looking and built tough. It has to be built this way, as FiiO knows that the A1 is going to take a beating. It is a device that will be constantly on the go. The aluminum helps to keep the internals protected from eventual drops and bangs. Buttons are easy to memorise and have a premium feel to each click.

The FiiO A1 is well paired with devices needing a little more power for some more sensitive and power hungry products. With the 3.5mm input/output, setup is quick and easy with no issues with compatibility or installed software to worry about no matter if you are using a computer, tablet, phone or any other device you are playing your audio from. Volume is controlled easily with separated [+] [-] inputs with 64 levels for use. The FiiO A1 also has the added ability to change the bass response with three bass boost options.

The FiiO A1 is a great amp for anyone looking to take that first step to upgrade earphones/headphones that may need a little more power. It is also a wonderful introduction to FiiO products for those new to the higher quality audio world.
