It's 2 for 1 special today, I'll give you two :)

1- Eagles - Hotel California version from Hell Freezes Over: The pinpoint accuracy of the horizontal line up of instruments and vocals and the encompassing low ends with the thump and control. If I can visualise the stage when I close my eyes with a sweet/warm sound signature. That is an enjoyable headphone.

2- John Mayer Trio - Out of My Mind: Just three guys playing their instruments with sparkly clean precision and feel. If a headphone can give you the feel of the control of the frequencies at the lows and highs while you can hear the song without uncomfortable booms from bass guitar and piercing snare hits, that is an enjoyable headphone.

Just my two cents...
