3M Peltor H6AV Optime 95 Over the Head Noise Reduction Earmuff, Hearing Protection, Ear Protectors, NRR 21dB, Ideal for Machine Shops and Power Tools, Beige

Comfy and useful.

I bought several pair of these to use in my classroom for students who like it quiet when they read or work. I wish I could buy enough for every student, because everyone wants to use them. They are not too big or too tight. These are the perfect "quiet headphones" for the classroom. I have been using them for years, and not one pair has broken. The ear cups have no holes or tears, and they get used daily. These last, and therefore are an excellent value if you are buying your own classroom supplies.

Estoy muy conforme con este equipo de seguridad es muy cómodo se ajusta muy bien no filtra casi nada de ruido yo tengo medidor de ruido y pues siempre es bastante lo que produzco entre 70 y 65 Entonces cuando el torno está cortando metales duró se eleva hasta 90 entonces con supresión de ruido es muy seguro, buena marca calidad y precio muy buenos aceptables estoy muy conforme con mi selección

Out of the box, the earcups didn't go low enough, resulting in an overly-small/tight fit. I thought these are non-adjustable and I'd have to live with the tight fit. If all else fails, read the instructions. So it was my delight to learn the earcups can be slid a lot lower. Now a perfect fit. By using the adjustment, these will fit kids to large adults. They fit comfortably but the headband provides a bit more force than I'd like - but it makes for a good seal and it fits securely even in bumpy environments. The ear pads are soft & cushy despite not being very thick. Overall, these are very comfortable once adjusted properly.Contrary to some other comments, I find the noise reduction is more than adequate. If anything, I'd prefer a bit *less* attenuation because I use these around the house where I like to still hear a little bit of what's going on around me.I've had cheaper hearing protectors whose plastic headbands eventually broke. The stainless steel bands of this one should last many years. These are semi low-profile, so the earcups don't stick out much, giving less of a goofy look when wearing hearing protection. Also love the understated, unique off-white color - nice looking without being flashy. Good job 3M, on designing a simple but solid, professional-quality hearing protector.

I usually work around quite a bit of noisy machinery which produce a lot of high pitch sound that causes lot of discomfort. So after wearing these the noise is reduced to a comfortable level.KEEP IN MIND that it does not eliminate noise 100% like you would expect an active noise cancelling device to do, it only reduce outside noise to a comfortable level.It is comfortable to wear and lightweight so can be worn for extended periods.That said it could be cheaper.
