3M Peltor Hearing Protector Earmuffs: Sport Ultimate (Grey)

早速、活躍してます。箱に凹みがあり心配しましたが、問題ありませんでした。

Peltor Sport Ultimate Ear Muffs 30NRR vs Peltor X3A 28NRR. Both of these are 3M’s latest upgrades to their line of passive hearing protection ear muffs. They are almost identical in appearance and design, and very close in their noise reduction ratings. I bought both in order to try them out and compare them to see if there are any important differences in comfort and effectiveness in use. Note that anyone working in an environment that requires protecting sensitive parts and equipment from low voltages or static electricity will be better served with any model from Peltor’s dielectric insulated X series including the aforementioned X3A. I find both of them very comfortable to wear, even for extended periods, and have no trouble sleeping with them when my neighbor runs his heavy duty generator which produces an exceptionably strong and constant low frequency hum in the 30Hz to 60Hz range. Not that loud, but loud enough to irritate me, especially when it’s on non-stop for 24 hours or more! In fact this is the main reason that I needed to upgrade my ear muffs because my older ones, while exceptionally excellent for most uses, doesn’t attenuate the low frequencies (100Hz and below) as well as these newer designs from Peltor. FWIW my older ear muffs are the well known Clear Audio design with a very wide price range depending on the name printed on them. Mine are the Browning HDR

Shuts out a lot of noise from my noisy ride on mower. Comfortable in use and allows addition of safety glasses.

Excelente producto. Se siente la calidad de los materiales, cuando te los pones crea un tipo vacio que anula el ruido, ya llevo 2 años sufriendo por el ruido producido por mis vecinos y su jo di da bocina, compre las orejeras con la esperanza de tener un poco de paz y no me arrepiento. Una bocina, literal a full volumen, a 4 metros de distancia, no molesta. Es como si la fiesta fuera a una cuadra de distancia, así que eso lo dice todo.

Excellent hearing protection for lawn tractor, push mower, gas trimmer. I have bluetooth hearing protection also, but I also wanted something without bluetooth for plain and excellent hearing protection. These are fantastic.
