Metrophones Isolation Headphones with built-in Metronome

Metrophones offer top-quality, stereo isolation headphones with Koss reference speakers. But the big plus is the dedicated click speakers and built-in metronome with an infinite-speed dial for on-the-money beats. Metrophones isolation headphones are equipped with On/Off switch, Volume control, and liquid-fill cushions for up to 29dB isolation. I don't use these much, they were my drummers headphones before he left the country. Open to reasonable offers/tradesShow less
