The EPH-100 in ear headphones are the result of Yamaha’s desire to enable you to hear not only clear music, but the sounds of the performer’s breathing or the bassist’s plucking of the strings, and even the emotions the artist put into the music. These new-concept headphones use a 6mm (1/4”) diameter super-compact driver to deliver the sound to your ears in pure form. Superb tuning only possible from Yamaha with its long musical instrument and audio experience reproduces every minute detail. With the EPH-100, you’ll fall in love with your favorite music all over again.
