Thanks to the 10 mm dynamic drivers with neodymium magnets, the E10 covers the entire spectrum of sound with striking detail. With rich lows, slightly forward mids, and sparkling, but subtle highs, every genre of music can be accurately transmitted without any instruments seeming out of place. Both earphones feature small openings that provide for deeper bass resonance and an expanded soundstage, bringing you far bigger sound than you’d expect from such a small device.
