Yesterday I pick up a pair of MX580 and I love the sound. Even without proper burn in, it became my instant favourite. It's detail, warm and sweet. I have a few IMEs but I prefer normal earphone, more comfortable for me. The UF10 is great, very clean, detail and fast sounding but the wire and large size is troublesome. I initially thought I will hate the volume control but it add almost zero weight to the earphone I must say. Instead of using it as volume, I do not mind using it as mute so I do not need to unplug or remove the earphone when someone is talking to me - nice I also find it good switching the volume to the lowest and use the line out from the TL-T51. Sweet, now I have a very clean sounding source.
