Is the quoted 20 dB reduction the actual NRR, or is it their value (often plugs are advertised with a reduction value higher than the technical NRR)

I can't say that the exact 20 db but I use them for shooting and they seem to work
1393911
According to their website it is approximately 20dB, I have tested others that offer greater reduction so I agree it is around 20dB. Do not use these for going to a gun range, they are insufficient, they are good for grass cutting or weed trimmer etc.

I don't know how to discern 15 or 30 decibels so hard to answer the statistical side. They didn't do much for me in a rock concert so I would look for something better.

My guess is NGK knows more about plugs than Amazon. Buy both, send back the wrong ones

The NAD is generating 50 Watts for 4 ohms. The PMC twenty are 8 ohm speakers so I think they would be driving them with 25w / channel. I guess it depends on how load you want to play music.

Hi TechnoTomI bought 4 of these to accompany the top section of my CLS215 (x4). I use the VE-5C for all my tops instead of the top section of the CLS as the CLS safety cut out is far too sensitive and dips after a short while. I use high end power so splitting across the 4 units I and pumping out 100watts RMS per box and they handle them just great. They do dip after long use but no way as sensitive as the CLS and they come back on after they cool down.Your 80watts will not trouble them but do not expect any bass as these are really for your top section only.Kind regardsLes Hi TechnoTomI bought 4 of these to accompany the top section of my CLS215 (x4).

Just checked manual and it refers to the website. To be honest, it sounds more like 100 W RMS than 180.

I am sorry .I don't know. I just bought them for my grandaughters, they are very happy with them since i have replaced the plugs many times with cheaper ones that died.

Old question, but for NASCAR and other VERY loud events where sound quality isn't as important, like shooting, a plug with a higher NRR is mandated. Like the disposable 32 dB plugs. Get those to preserve your hearing. Get these for concerts.

Not Sure. If u posted a picture I may could tell you! But for the price u can't go wrong. It has cut 90% of noise reduction. I am going to order a second one for Back up in case they get making them.

Not really that kind of product. I can tell you from personal experience that the noise level reduction with the plugs in place is at least 70 percent compared to the level experienced without the plugs in place. I find them to be fantastic. Cuts down snoring to virtually nothing and diminishes TV sounds to barely audible.

It says "electronic hearing amplification to 82dB". Not really sure what it means or if it answers your question, but I have read reviews of deer hunters that swear by these. I cannot confirm this since I have not used them in such a fashion. Hope this helps.

Just for the record, earmuffs don't HAVE decibels, they ATTENUATE (reduce) sound pressure levels. This reduction is expressed in dB by what's know as the NRR (noise reduction rating). For electronic earmuffs, this one is pretty high at 25 dBs - if the manufacturer's rating can be believed. The thinner, lighter ones are usually around 22 dB, and the very expensive ones can be as high as 30 dBs. The non-electronic ones are much cheaper and reduce sound by much more than the electronic ones (except for the super expensive ones).

I was also curious about this. My friend has a pair of M9 with the 45 degree plug that he got a few months ago, but the pair I ordered has a cheaper looking 90 degree plug, and the packaging is much different. I was unable to reach the manufacturer; the phone number listed on their website went to the voicemail of some guy named Marty with a strange accent. It's not a huge problem, as the headphones still work just fine, but I want to make sure I got the same product I paid for.If I'm able to find out anything else from the manufacturer or elsewhere, I will post it here.

Page 13 of the manual shows it better than me trying to explain it. http://www.hitachipowertools.ca/upload/fmproduct_filen/NP35A_OM_10850.pdf

I couldn't give you the NRR number, however, I worked in a very crowded area with echos and these work amazing at blocking outside noise and allowing you to hear the radio traffic. I've used multiple designs and I have always continued with this one. I have only ever had one defective one that was muffled sound and it was immediately replaced. The only "downsides" is if you are extremely active and have little ears then these may fall out. It is very difficult to hear out of the ear that you have the plug in, but that is because it is doing it's job properly and blocking the outside noises. It does a great job!

dB reduction stands for dB=decibel. The reduction of noise level or reduction of dB/decibles. Also interchangeable with NRR=noice reduction rating. The Howard Leight ear plugs have a rating of NRR 33. Foam ear plugs are found at sporting good stores with a NRR of 32. The higher the NRR #, the better the dB of noise reduction. So, the Howard Leight foam ear plugs have a 33, a better reduction of noise.

The one i recieved had the L-14-30amp, i zoomed in on the picture, and it has 30a ends also ,10/4 wire, probably just a typo on the L-14-20, its works great, seems to be good quality and the cord is very flexable, have a great day !!!
