Hi, you know when i saw MCA thread, i remember he is working in a live and w/o booth envorinment. I only know that when there is a band, there will be noise and if you need a pair of hps, you need to have it isolated. So that is when EX-25 comes into my mind and let him view the product on the website since he is gathering cluesss and info from ......
M30 indeed is a great pair of headphones for studios and in fact has turned some users from buying some " expensive " monitor headphones. Studios are using them for their talents. But.... Live performance wise, it is fine but just giving him more choices, which is what he needs so tt he can A/B test.
Earplugs works great! Isolation definitely as goods as my 2 index fingers. But i would like to really know how the Crash, kick sound when MCA do his first recording with the mentioned 100bucks earplug. But make sure it is able to take the level he needs before distortion. Still hope to hear from him what he buys in the end.
