It's no surprise that Bose has knocked it out of the park again with their Soundtrue headphone. They are by far some of the most comfortable headphones I have ever used. I have gone 10+ hours wearing them and never experienced any fatigue. Being Bose, they obviously have superb sound. They are not too bass heavy, so sound is not muddied. Because they are an around-ear design, sound leakage is very minimal, and isolation is also fantastic. It should be noted that these are NOT Dj or producer headphones. I'm sure you could use them as such, but I would not advise that. These are more just for listening enjoyment. If you did want to use them in the studio, these would be great for vocal recording. Because the bass isn't too intense, vocals shine with these headphones, and combined with the minuscule sound-leakage, you wouldn't have to worry about a mic picking up any extra sound from them.
