Conclusion: Klipsch did well with its first go at a full size, noise-cancelling headphone. The M40 look terrific and its noise-cancelling prowess is as good (in some cases better) than similarly priced competing models. In terms of audio, we found ourselves being pretty critical due to the $350 price tag, but the M40, with some break-in time, will make a lot of listeners very, very happy with its ample bass and superb treble response.
Pros: Excellent noise-cancelling ability, Superb treble, and ample bass, plenty dynamic, Look terrific, lots of extras, Long battery life and plays without battery
Cons: Fit may be too tight for some listeners, Inconsistent midrange response, boxy sound on some material
Excerpt: They come with a straight 3.5mm audio cable, another cable with iPod/iPhone volume and Play/Pause buttons, an airline adaptor and a 7.5mm audio jack adaptor. The iPod/iPhone cable includes a microphone so the M40s can be used to take calls as well. All of this can be easily carried in a solid case that will easily fit into a traveller’s backpack.
Conclusion: All in all, the Klipsch Mode M40s are a success, just losing out on a fifth star because of the tough competition. There’s plenty to shout about here, even if you can’t hear it over all the noise-cancelling.
Pros: Excellent noise-cancelling, Tough build, Smart looks, Good battery life
Cons: Could be more comfortable, Faces tough competition
