I'm not the type of person to spend more money than I need to get a quality product. I wanted a quality headphone for multiple devices without taking out a small loan! I took a gamble on these Aerial7 Tank Thrash units based on the spec's. I'm glad I did. I require head phones which simply perform and must sound really good. To my surprise, these headphones sound wonderful. I listen to mostly heavy metal, "thrash" and all other forms of rock and I will say these headphones deliver a real hardcore performance. Full range sound is reproduced pretty darn good! Bass is very solid, however will not exploded your head off of your shoulders! Mids and highs are clean, tight and accurate. With my headphone amp, these puppies go Metal Concert loud and louder without any distortion! My htc One V with beats audio sound pretty sweet however will not go super loud! The microphone cable does not have a screw lock to the headphones like the DJ cable has. The "thrash" band on top could have had the Kerry King spikes of death to really set this headphone off as a hardcore unit!!!
