The only downside is they are wired and have a small Lithium battery pack on the wire to power the active cancellation. Bose QC30s are wireless equivalents, but from what I've read are not so efficient at noise cancellation. Not sure about the health&safety implications of wearing noise cancelling headphones at work though (not hearing alarms etc.).

They do come with a little heavier price tag than most - but from an acoustic standpoint - they are the best. If you are just looking to cancel out background noise, then there are some cheaper alternatives with close to the same quality - Audio-Technica (ATH) makes several noise canceling headphones (wired and bluetooth). The Samsung Level On's are about half the price of a pair of Bose and are bluetooth NC headphones. Whatever you decide to go with, get "on-ear" or "over-the-ear" headphones. They are far superior to "in-ear" buds, in both technical performance and comfort (in my opinion). Bluetooth has its obvious conveniences, but audio quality is typically not as good and they are almost always cheaper than bluetooth.

They could do wonders. I still have the box a company constructed for the 2 fans of the Krypton Argon lasers which reduces the ~70db noise to a hum (the lasers are long gone!). They also did some things for the chiller for our TEM to make our lab space workable again. Noises and the darkness in a facility give me headaches. This is the least you could do for your users... As to noise cancellation headphone, I have been a long Bose user and are happy with it (both the Quietconfort 15 and 35). But both came without me paying for it, I am sure there are better price/performance choices. I cannot tolerate in ear headphones which is just me..

However, the acoustic isolation of most materials increases greatly above 1 KHz. If you want to isolate higher frequencies, tight fitting inner ear headphones (IEMs) can be extremely effective (1000-fold attenuation or more). Tightness of fit is key however, as any air leaking around the edges will undermine the isolation. For what it's worth, when I was aligning a microscope using a 4 KHz resonance scanner at 25 degree deflection, the sound was deafening without ear plugs. However, just using a $20 pair of Creative EP-630s (about the lowest quality IEMs you can buy) reduced the high frequency noise to a very tolerable background human while I listened to music at comfortable volume. The key was to use the largest insert size they included, which was very tight fitting and blocked out airflow entirely. I'm sure if you spent more you could get something even better.

Actually optimizes on the fly and best of all it's wireless. I also echo the suggestion of others of a good custom in-ear-monitor but the costs could be prohibitive. What you can do instead is go to a hearing clinic and actually get custom in ear plugs (without the electronics) that may serve a better job than standard foam plugs. You can get them in silicone or acrylic. |

Not very effective in the frequency range of the human voice from 1500 - 3000 Hz. Comfort on ear for lengthy sessions of wearing is 4 out of 6. Sennheiser PCX 550: Very good on noise from low to high frequencies. Less effective in the frequency range of the human voice from 1500 - 3000 Hz than the Bose QC 30. Comfort on ear for lengthy sessions of wearing is 6 out of 6. Bowers & Wilkins PX Wireless: Very good on noise from low to high frequencies. If you use the app with it you can nicely adjust the opening / closing of the frequency range of the human voice, sort of like an inverted equalizer. Comfort on ear for lengthy sessions of wearing is 5 out of 6. They look very posh, that might disencourage some people from using them in a professionel environment. All of them cost around 400 €. My favourite at present is the B&W one.
