FiiO A5 overview

  • 1Description

Building upon the success of the E12 series, the black Fiio A5 is a headphone amplifier designed to be used on the go and provide a hi-fi sonic backdrop to any traveling situation. The A5 utilizes the same combination of opamps (Muse02 + LME49600) as the E12A, but delivers improved performance with high precision components that provide better harmonic distortion, a higher signal-to-noise ratio, and an improved channel balance.

The headphone amplifier also sports an 880mAh battery which can last up to 13 hours on a 2.5-hour charge when supplied power via an optional 5V/2A charger. When charging, the A5 will automatically adjust the amount of current it accepts depending on whether you're using a computer's USB port, a tablet charger, or a cell phone charger. An LED indicates the A5's charging status.

Furthermore, the 1/8" headphone jack utilizes a CNC stainless steel ring, rather than copper, which was used in previous models. This, combined with a plastic ring, ensures the termination port is integrated with no gaps whatsoever, giving you a sturdier connection for your headphones. The amp accepts signal through a 1/8" jack located near the headphone jack, and features a switch that allows you to adjust between high and low gain settings. The A5 ships with a USB power cable, two silicone pads, four silicone bands, an 1/8" audio cable, and a cloth pouch
