Studio Grade Amplifier & Bass Boost: Breathe new life in to your favorite headphones anywhere you want to go. Serious power in the palm of your hand with 6+ hours of continuous play time on a full charge and inline controls. The World's Smallest THX AAA Amp Design Delivers an incredibly clean and linear amplifier into the palm of your hand. The DB12 AAAMP delivers a no-compromise headphone audio experience with the highest fidelity audio. Greater dynamic range, sound pressure level, and an enhanced (or as we prefer to refer to it “UNMASKED”) stereo field for better spatial imaging. Plug & Play Designed for Our Mobile Audio World: Connecting to your smartphone's budget-and-size friendly (but not high quality headphone friendly) audio output, the audio signal is boosted by a clean +12 dB ready to feed high-impedance, high-current, and high-sensitivity headphones. More Bass Please: No modern headphone amplifier would be complete without the ability to punch up some low end, so the DB12 can independently add +6 dB of low end to the signal. THX Certified For Jaw Dropping Amplification: Studio quality audio in a tiny fob-style design outperforms other amplifiers way above its size as it steps up your mobile device's audio output with infinitesimally low levels of noise, distortion, and power consumption.
