MSA 10129327 Non-Electronic Helmet Mounted Earmuff, 25 dBA

Solo llevo un mes con ellas y son excelentes para mi casco de ala ancha ya que atenúan bastante bien el ruido de los turbo compresores, ya después de mas adelante escribire si son duraderos, las almohadillas no son iguales a la de la imagen porque son de gel segun averigue, estas son mas modernas que las de la imagen, al principio calan porque no estaba acostumbrado pero ya despues te acoplas

Love these muffs and yes they fit most full brim hard hats!

A great MSA full-brim hardhat accessory for those who work around noisy equipment. Snaps right into place in the MSA hardhat side slots and provides a comfortable and quite work environment, these clamp well enough to work great over a hardhat liner, which is nice in the winter.I chose these over other designs because they specifically work with full brim hardhats, as you can see by the probounced crook in the arms, many other brands only work with the Cap style hardhats.These things are good quality, they easily fold back and ride along side the hardhat dome when not in use, making transitions between loud and quiet environments easy. When worn over the ears provide a very secure hardhat attachment. They do add a bit of weight way up high, but it's worth it for me working out of a pickup truck maintaining gas compressors stations where exteame noise levels from Cummins and CAT engines and compressor Blowdowns will deafen a guy in short order.Though they are $10+ more than other well known models, I highly recommend this style for it's specific design meant for the MSA full brim models. The alternative is an earmuff set with the behind the neck crossband.

Finding ear muffs for a full brim hard hat is a bit more challenging than a regular hard had, but these fit the bill.I had a previous pair that are the wire mount (as opposed to the plastic) and they never really seemed to fit right or block that much noise. Not so with these. The plastic ones are AWESOME. Much tighter fit that blocks out much more noise (primarily due to the fit I am sure). I often wear in-ear headphones under these and they are much more comfortable than my other set.)My only non-raving review comment would be that because they are such a tight fit, after a while they can get a bit uncomfortable, but not unbearable -- especially given that they block much more noise than other options.

Fits great
