A1 Portable Headphone Amplifier

With a hi-fidelity output that outpaces all smartphones, the A1 Headphone Amplifier satisfies the need for high-quality audio from a digital device. This small, lightweight amp has a durable modern appearance with sensitive and reliable volume buttons and a 3-color LED status light on the power button that indicates its fully-charged with a green light, charing with a red light and low on power with a flashing red light. The battery is fully rechargeable with a 13-hour playtime. 

The device also has four EQ modes for maximum flexibility which can be switched by briefly pressing the power button. The indicator light will appear differently depending on the EQ mode: a blue LED on continuously is flat mode, the blue LED flashing once every 2 seconds is Bass 1, the blue LED flashing twice every 2 seconds is Bass 2 and the blue LED flashing three times every 2 seconds is Bass 3.
