This mic is definitely sensitive. With 100 pairs, I was able to take about 10 (more than sufficient for me) and put them in my travel bag, but for quick access I put a pair in the travel container it comes with and put it in my purse. As for the surround sound, let me put it this way. - The case look solid and durable. Rarely am I amazed at the quality of a product because as a consumer Im so used to purchasing items that are just okay. So if you wear a half size, and you like your toes to have wiggle room order a half size up. Well, I did what any girl (even and old one, like me) would do and just ordered another pair in black. Battery charge is average and so is battery life. I found the pads actually more comfortable than the Bose, very similar to Sony 1000xm3. After that going on randomly for a couple more years I figured I would look at another set of headsets.
