For anyone who wants their music to sound as good on the go as it does at home, the Sennheiser IE 80 IEMs have a lot to offer. Equipped with dynamic drivers and powerful dynamic magnets, they have a low impedance well suited to portable devices (from smartphones to high-resolution media players) and 26 decibels of ambient noise attenuation to ensure your surroundings don’t get in the way. The factory setting delivers clear, detailed sound with a wide frequency response to faithfully reproduce every instrument. And if it’s not exactly to your liking, you can easily adjust the bass response using the included tool.
