I personally use Elacin Clearsound. They get fittet to your ear, so they are extremely comfortable. They have 3 variants of special filters to choose from. Eacht beeing more silent then the other.
I use them when playing drums and attending live shows and band practice. Here I use the strongest filter.
The BIG advantage is, that they only make stuff more quiet. They dont distord the sound at all like with many other cheap ear protection options.
But with 160€ here in Germany there are quite costly, but last a livetime it cleaned regularly.
