Do you need headset/mike? I reckon a portable headphone is about half about good ergos. If you need it for phone duties I'd say the M-80. but cable noise gets in the way of calls outgoing voice sometimes due to the cloth covered cable.  Still, I really like them.  The P5 is awesome if you're not looking for grreat sound.  The sound good enough without fatal failings, but the ergos as a headset is stellar, no cable noise, and spanky good looks and feel.  Isolation is amazingly good as well for an on-ear phone .... comfy too.
