We should have probably sent a copy of a Black Sabbath and/or AC/DC with this great pair of Iron Man Retro Image Noise Isolating Earphones! That way, you can listen to 'Iron Man' or that 'Thunderstruck' song made ever so popular by Marvel's Mr. Tony Stark! You know Stark blares music through that Iron Man suit, but it turns out that's actually a really expensive way of playing music and shipping costs are insane for a 2 ton piece of human battle armor. Luckily for you we have the Iron Man Retro Image Noise Isolating Earphones which are comfortable earphones featuring Iron Man's face and they are compatible with almost any mp3 or audio device!
