Summary: Tight headband. Boring sound. Further, these are NOT noise cancelling headphones - they are noise isolating headphones with a built in amplifier. I dismantled them and found no noise inversion circuitry or the required external noise sampling microphones which are used to sample external white noise. Overall, my aging Sony NC50's do a substantially better job.
Summary: The price was what appealed to me more than anything when I bought this product. The full price (as charged in Apple stores) is around £300 so they appeared to be a bargain. They ooze quality and are supplied with an excellent leather case, an additional cloth case, two fibre covered cables (one with inline remote and one without), and an airline adapter. The noise cancelling performance was very good, not quite on par with Bose but more than adequate.
Summary: bought this one on boxing day ,sorry to say that it was a dissapointment...........thought the deep discount would be a good buy ,but not true (hence the the m40 has been discontinued by klipsch).noise cancellation does not exist at all ,sounds ok retur,ned and got a cheaper one (jvc XXmr77x)..that sounds crazy good !!!
Summary: Bought this on Boxing Day sale and returned them a week later for a pair of Bose QuietComfort 15s. Sound was pretty good on the M40s but they were really uncomfortable for me - too tight and hard plus they were quite heavy. Don't recommend them. No problems returning them...
Summary: Sound quality and comfort do not reflect the sale price, they are uncomfortable for my average sized head and the sound quality reflects a much cheaper headphone. The positives are that the build quality is great and the passive noise isolation is quite effective.
Casque trop lourd avec annulation de bruit inexistant

Excerpt: Le casque fait mal à la tête. Le son est trop fort lorsque lo'on regarde une vidéo Youtube. Et l'annulation de bruit ?? Et bien je ne sais pas ou elle est car j'ai un Bose Qc15 pour lequel cela marche parfaitement
