Introduction

Meet the Sennheiser CXC 700s, a set of active noise-canceling in-ears that are probably best used on an airplane flight. While these headphones are not well-suited to use in the outdoors, or at a computer, the active noise cancellation unit employed by the Sennheiser CXC 700 offers slightly better attenuation than most on-ear or over-ear headphones. Still, there are some significant durability issues that should give most people that are not frequent travelers some pause.
