Our take on the Sennheiser HD 218i

by Dave Bar

No matter where you roam, Sennheiser's HD 218i headphones will bring you closer to your favorite tunes. You get dynamic, hard-hitting sound and a lightweight, portable design that's comfortable to wear for hours. The soft, closed-back earcups help screen out surrounding noise — the clatter of the train or the chatter of people sitting next to you — so you can immerse yourself in music. Sennheiser also designed the HD 218i in conjunction with Apple® to provide easy control of the music loaded on your iPhone®, iPod®, or iPad®.

Easy switching between calls and music
A three-button remote control built into the headphone cable lets you conveniently answer and end calls on your iPhone, control the volume of your calls or music, and pause, play, or skip through your songs. You can even take calls on your iPhone hands-free, thanks to an in-line microphone. The mic is specially designed to hone in on your voice so you won't have to worry about surrounding noises drowning you out.
