Logitech enters its phones into the battle royale between noise-canceling headphones, competing against Bose Quiet Comfort 3 and Solitude headphones for the title of King of Quietude. It's using the same principle as its competitors, with active and passive noise elimination aiming to cancel out constant background noise such as that encountered on an airplane. Also like its competitors, the Logitech headphones include a plush carrying case, a double-jack adapter and a detachable headphone cable.
Three of your humble editors here at Gizmodo have auditioned the Logitech headphones' competitors, the Bose Quiet Comfort 3 and Solitude headphones with mixed results, voting two-to-one in favor of the noise cancellation concept. I've compared the Bose Quiet Comfort Headphones directly to the Solitude headphones at 35,000 feet, and it was hard to tell any difference between the two.
