The air temp is only slightly warmer than ambient, so it doesnt do something stupid like re-heat-molding your liners. Mary Jane on the other hand does work for the Daily Bugle in this version of the character. The light weight, voice activation is Wonderful. I am not an audiophile so I am not big into how awesome these sound. I want bass you can HEAR. Overall I am very happy with this purchase and would definitely recommend it. A bit pricey for what it is but hey quality costs. What is absolutely unacceptable however is the fact that whenever I accepted a call, the audio wouldnt appear on the earphones but on the earpiece of my phone. I live in chronic pain, I have RA, bone spurs, fibro, flat feet, - I hurt all day every day. Firstly, the sound quality is amazing.
