Automatically Adjusts the Amount of Current it Accepts

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.

Sturdier Connection

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.
