Great custome Service ! A good mic is the very basis of a good recording. no breathability. So, I just really pleased to get a product that works well, great battery life, performance is very acceptable. For me, they plug into a single 3. They clearly feel like plastic and are useless. Slipper slightly bigger than my foot but still comfortable to wear and the memory foam soles are excellent My basement ceiling is around 86-87 inches of height. 5 or 10 in normal shoes, 10 in Martens BOOTS. Does what it says it does in the description perfectly.
