Because these headphones will suck it out and embarrass you. Never had any complaints from people saying I sounded like I am in a tunnel or that they couldnt hear me. Ive been using this stereo mic on my Sony A6000 for a month or two, and it is an improvment over the mics built into the camera. The only complaint is I have to wear socks because the strap on the left foot iratates my ankle bone. My true foot size is but I usually I purchase size 12 wide shoes, since toss out the insole that come with any shoes and instead use a thicker MEGA Comfort anti-fatigue mat (insole). I was surprised to find that there really isnt anything else like this on the market. ), essa Audio Technica, com toda a certeza, não decepcionará. I highly recommend this door hanger! HOWEVER - all my Minnetonkas (usually Kiltys) have all been size 8 1/2 and fit really well. I also picked up a pair of Sanuks (I have a slip-on by them thats been incredible) at triple the cost for something a little more heavy duty.
