Logitech has an extensive line of cell phone and gaming headsets, but the company has made a few rare departures into the world of portable audio headphones with products such as the Curve Headphones and the Wireless Headphones for MP3. Another such product is the $150 Noise Cancelling Headphones, a sealed earcup-style headphone with passive as well as active noise-hushing capabilities.
Logitech wins style points for the Noise Canceling Headphones' modern-yet-understated design. The fully enclosed earcups, which twist to lie flat for easy storage, form attractively curved rectangles, and the black and brushed-charcoal coloring is sure to have nearly universal appeal. A soft, pleasantly smushy padding lines the inside of the cups and conforms nicely to the contours around the ear. However, the bottom edge of the earpiece pushed the backs of my earrings uncomfortably into my neck--a typical problem with earcup-style headphones (and the reason many ladies, and some men, prefer earbuds). I also found that the headphones exerted a slight pressure on the back of my jaw that turned into an uncomfortable twinge after an hour or so of use. The padded headband, though, is comfortable as can be: it's adjustable, and it leans slightly forward for an ergonomic fit.
The Logitech Noise Canceling Headphones come with a nice array of extras, including a removable audio cable that measures approximately five feet long (plenty; it's also thinner than typical over-the-ear headphone cables). There's also a well-designed hard-shell travel case, which offers a Velcro loop for the cable, earcup molds, a AAA battery cutout (which is where you'll find the included AA battery), a small square pocket with a picture of an airplane on it (for the included airplane audio jack adapter), and even a slot for your MP3 player. The latter appears to be sized with the iPod in mind, but really any like-size (or smaller) device should fit.
