A Lossless Listening Experience

Featuring a clean design, built-in battery, and four-pin balanced output (a rarity at this price point), the Fireye HDB portable amplifier allows you to get better sound quality from your audio player. The dual amp circuit boasts an LME49724 and TPA6120 amplifier, and delivers plenty of power between its three gain settings: low for sensitive IEMs, medium for higher-impedance portables, and high for everything you normally keep on a desk. Of course, providing adequate power isn't just about volume—it's about driving your headphones fully at whatever volume you enjoy, and the HDB will carry you from M50s to JH Roxannes without the need to upgrade.
