Hi,
I needed to buy quickly because the new attenuators band plays hard.
I looked at the web and I found that a first test for this type of caps would be nice, and the cost-to-measure still expensive.
I found a shop on the internet and I paid 16.97 euros with the small string, a small storage box flexible and convenient shipping included (shipping within 48 hours by mail).

I have for a week and the first repeat, you really get used to it, it is not obvious.
They are very efficient, reduce greatly and it is true that it seems to be acoustically protected. They do not hurt the ears and fit very well, it's silicone pout, so it's soft.
on the other hand, side of the coin, the sound is not the same. You do not hear "aggressiveness" of my amp and I have less feeling to play: so you need a bit of experience to use and enjoy.

Recommend, because after 3 or 4 hours of music, you have no brain buzzing and you can rest easy after.
For the price, and given the choice I would do without hesitation.
That's why I put 10/10.

Peter
