The FiiO A1 is an ultra compact headphone amplifier that increases volume and audio quality of your portable music player. The AMP is a significant improvement compared to the prior model based on its durability, design, and increased drive capacity.
Small but powerful:
The FiiO A1 is designed to improve sound quality over the levels offered by the E06. The A1 is also designed to offer indicator lights, dedicated volume control, and an added removal clip, which makes the A1 the most portable device FiiO has to offer.
Tiny Size:
The A1 fits perfectly into the palm of your hand, which allows for extreme portability and ease of carrying.
Indicator Lights
The A1 has built in LEDs to indicate whether it is charging.
Long Lasting Power:
The A1 has a built in battery which lasts for up to 13 hours of continuous playback.
Removable Clip:
Each A1 device comes with a removable clip which allows for easy control of the device.
