Absolutely love them. I got myself a Digital to Analog Converter to realize the full potential for these phones. Crystal clear and great reference. I listen to all kinds of music and these phones do an amazing job at reproducing. I own BeatsPro and Monster Inspiration...I never listen to those anymore. They can run straight off a phone or pod and don't need an amp....but, when plugged into my DAC that runs from my computer.........OMG.....Perfect! These phones are amazing.
