I have owned m50 and vsonic gr04 for a month. They are good. Gr04 actually sounds clearer and a bit louder than m50, but with m50 I feel the vibration more.

But I wonder how other headphones sound like. Will I find grado 60i, superlux hd668b, or panasonic RP-HTF600 interesting at all? Will I find them clearly inferior to m50?

Thank you for your opinion!
