whats the NRR noise reduction raiting?

If your asking about background noise threw the earbud it isn't too bad. I worked as a security supervisor for a 100,000 square foot club that holds 6000 people with live LOUD music and had no problems hearing the calls. I do need to warn you about the quality of these headsets if your job is physical . I was frequently in take downs so mine took a beating. I went threw 4 of these in a year. I had bought some for a few of our door guys and they loved them! No problems as far as wear and tear on thiers. Hope this helps.

The NRR on this item is irrelevant as it's nothing u should purchase. The outgoing comms were zero functional & incoming was barely audible (yes,volume maxed). Garbage.

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!

I don't know how much decibels this will reduce. it is very effective against noise but think twice before you purchase it. it is expensive and very heavy. hard to install and it will be hard to put a drywall on it because of all the wrinkles.

Hi, this item will not completely Cancel Noise . It would only dampen noise. Noise Reduction Co-efficient (Hz): 0.3

A couple of light coats reduces a bit of noise but not by much. Use it also in the wheel wells. Use of extra carpeting inside and the trunk area probably does as much. Be careful of GAS Pedal interference on drivers side of cabin if beefing up carpet around drivers area.

These 2 items share the same Sony Manual shown as MDR-RF925RK and MDR-RF970RK. I scanned the manual for differences. I found that 970 has noise reduction, 925 does not. Also when fully charged, 925 lasts 20 min longer for every hours which ends up being 4 hours longer on a full charge. Here is the link https://docs.sony.com/release/MDRRF970R_US_FR.pdf

Yes. The noise reduction is very good. You can drown out the outside without having to shatter your eardrums.

I love the product, plus whenever you use the dispossble filters they always make a lot of noise when the sie condition or hearing comes on, with this ones we do not hear any noise. Plus it is better for the environment!

If you wanted to suppress humming noises you could use Nexus Case Fan Vibration Absorbers - Set of 4Nexus Case Fan Vibration Absorbers - Set of 4

The white noise feature blocks out some of the unwanted noises that you hear.

The unit is about medium noisey. Naurally the faster fan makes more noise. But as usual, once it on for awhile your hearing ignores the noise.

The factory setup is virtually noise free. Put the stock unit back on truck. I will probably put a good filter in the box & leave it alone. Wasted $260.

Hell yes just leave the silencers out! I'm cutting out my resonator behind my cat on my 04 ion even though my neighbors already complain that its too loud! I love this muffler!

Here is what I found... These uncorded plugs are rated NRR 32(or Noise Reduction Rating of 32). NRR is calculated by unprotected ear dB levels minus protected ear decibel levels minus 3 dB. The higher the NRR rating, the better the protection. They work really well for what I use them for, which is to sleep :-)

It's not the focus!! It's the overly aggressive noise reduction! No way to turn it off unfortunately.

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.

With the "silencer" on its not unbearable. With it removed its LOUD AS HELL. Not even kidding. There are a decent amount of videos on youtube you can check out as well

I have a slight noise on mine only when using the onboard microphone. Since I do not use this microphone, it is not an issue. I have hung a rode NTG 2 on the camera and recorded sound as close to the lens as the internal microphone. Not an issue. All Camcorders do this...... Manual operation will eliminate the noise as well. Good Luck!
