Nope I don't yet- but I'm planning on it. You can PM me for details for now. I'm going to offer a free review pair program soon.
Can you mod brainwavz hm5 because internally it looks the same like senhiesser hd6xx series. They are a great set.
Sorry, as of now I have no such plans. I'd have to modify each pair myself because I have to do driver matching.
