I had some semi iso Sennheisers back in the day (Koss b4 those) , they worked pretty good. Wouldn't mind having a buck for everytime I listened to Robin Trowers' Bridge of Sighs or Edgar Winters' Frankenstein on those phones. They mixed and reproduced the music in your head (quite well actually). I like the speaker experience, but headphones can be a little more personal at times when you might want a little isolation and peace.
