Gunmetal TH1 Closed-Back Audiophile Headphones with Vacuum Tube Preamp

Experience the world's first and only headset with a built-in vacuum tube preamp stage and dual-mono amplification. écoute headphones are designed to deliver a true vacuum audio listening experience that is both warm and precise. The bass is deep and clear without overpowering the midrange, which is exquisitely rendered with clarity and nuance. The treble is extended and airy, delivering a sense of openness and detail. The wide soundstage and realistic rendition of vocals and instrumentation sounds less like your music is being reproduced on a piece of audio equipment and more like it is being performed in front of you.
