I was literally opening it up to solder in some Kailh GM 8. Adding the wind screen did lower the level of noise, but the result was a low rumbling rather than the mild hiss with the built-in mic (and wind noise reduction). Feel sexy wearing them and look forward to the right occasion to wear them again! Another thing I really like about these headphones is how they look when I am wearing them. I?ve lost several already, but that?s my own fault. Got a great price on these black shoes. The swivel feature is great. No one likes to listen to an unbalanced mess or poor positional audio precision. These sound great, are easy to charge, fit perfectly, and STAY ON MY EARS when running! It came with incomplete screws assembly parts.
