Driving Glove

Designed for Astell and Kern’s AK100 and AK120 music players, the GloveAudio A1 is more than just a protective casing. Featuring the lowest noise floor and super-low THD, the A1 extends the battery life of the player by outsourcing the DAC/Amp circuitry and improves the sound quality with its precisely-nuanced, fully balanced 2.5mm and mini 4-pin socket output jacks. As the A1’s battery lasts over 10 hours, you’ll be enjoying the highest quality music for as long as you need.

Power Within

Capable of delivering 3.2 V RMS at 32 ohms on balanced outputs, your AK100 or AK120 will be well-equipped to drive headphones like the HD 800 or LCD-X with authority. With clickable volume up/down buttons on the A1 taking over duties from the Astell and Kern volume knobs, the intensity of your music will always be exactly as loud as you want it to be.
