it worked! Im going to stick to using coconut oil. What they give are a few screws and a paper-ruler. Im sure to a professional, there are many things wrong with this mic. These are high quality ear buds. One added bonus--drivers of high-profile vehicles (monster trucks, etc. I can even hear the sound leakage from ER2 on my desk clearly. Great for listening, but definitely less analytical. They are also pretty stretchy which makes them even more comfortable I really recommend these! This does not look or feel like a cheap case.
