Interesting product. These earplugs do not cut off an audio frequency range as usual, but they attenuate the "volume" of the sounds in your environment. The first time I tried them, I wondered if he was doing anything. They must make a uniform noise reduction (bass as well as treble) of 20db (20db is huge, it's 10x less loud). Honestly, I don't know if this number has been reached, because I can still hear my environment very well. I can even follow a conversation without difficulty. In a noisy environment, personally for my ears it is always noisy. But there is indeed a reduction in noise, it should even be said a reduction in perceived sound. But I don't estimate this reduction to be 20db. However the ear is a sensitive organ and the measurement of sound a science so sense professional measuring device I can only give a feeling. I'm pretty sensitive to ears and I have very small audio conduit, it doesn't necessarily work in my favour. I can confirm without a shadow of a doubt that the wearing is very comfortable (even for my small ear holes). Removal is easy if care is taken to properly place the tab. Cleaning is also easy, just a little slow water and a gentle wipe. The box is also very practical without being too voluminous, I attached it to my keys and followed myself everywhere. I still recommend this product for people who want a slight reduction in sound to stay connected to the environment. Like in an open space, if you have sensitive ears like me. If you are thinking of protecting your ears from particularly loud noise, such as cutting tools, a lawnmower, a pneumatic or electric striker, etc... I recommend another type of earplug. The particularity of this one is not to mute a type of sound but to allow a less loud listening. That's how I use it, in the car, at the office or to sleep (less to hear my darling's snoring but to be able to hear my alarm in the morning).

Ph4nt0m Be careful friend. To connect 2 boards for more power, you need to modify one board. Each board have own sinus generator. That any COM exist to synchronise the sinus signal, you need to remove one sinus generator on the board and share the other between bobards. If you dont do this, you quickly destroy 2 bobards. Not very difficult if you have some experience with electronics. Other else forget this idéal ! It is my professional words. Sorry for my english, I use it only for read technical documentation (I have not a good student for language except for programmation :) ).
