Comparison:
I decided to try these. Compared to my usual foam plugs, the noise reduction of the NoNoise plugs was pretty average.
After trying various different plugs over the years, I’ve ended up using
Flents Quiet Contour Foam Earplugs. They give good noise reduction, I find them comfortable and they’re super cheap.
I bought some
NoNoise plugs and gave them a back-to-back comparison. Started off with the NoNoise plugs. They inserted into my ears very easily – no messing rolling and compressing them like foam plugs. The NoNoise plugs are extremely comfortable – could barely notice that there was anything in my ear. When I started riding, the noise reduction seemed good.
I switched to my usual cheapo Flents. I immediately noticed they are quieter. That was a surprise. The Flents have a NRR 33 noise reduction rating whereas NoNoise quote a mean sound attenuation of 29.6dB. I suspect they’re being rated by different methods (US vs. European), but the numbers reflect what I experienced - a noticeable difference in favor of the Flents.
NoNoise make a point that they don’t filter out communication. I use a Sena Bluetooth setup to give me radar detector alerts. The NoNoise plugs were noticeably better than the Flents at allowing the sounds from helmet speakers to come through. The volume and clarity with the NoNoise plugs was pretty close to no plugs at all. Good performance there.
Price – there is no comparison here. I paid
$26 for one pair of NoNoise plugs. The Flents cost me $1.79 at WalMart for a box of 10 pairs. OK, price is not the primary decider, but you get more noise reduction from a product that is cheap enough to throw away and grab a fresh pair after a couple of uses. That’s hard to ignore.
Now I have the NoNoise plugs I will use them. If you use a communication system, then they’re a very good choice. If you’re just looking for noise reduction you can get more for a fraction of the price. For ultimate noise reduction, custom molded plugs or active noise reduction must be the way to go. I haven't tried either of those, although I do have a ANR aviation headset so I know they can create quite a serene environment.
