Got these while attending briefly Cash-Jam (2 day multipass OC edition). The packaging is not much to write home about. No endangered three species wood. No diabolical signs. Oh Well. I think they look alright tho ...
Box says "Bio Cellulose Drivers", just like the R10s! The cups say "Creative" and daz dat. Unlike the boobs-like R10s, the CAL! cups feel sort of cheap. But the build of these headphones is not bad at all. The cushions seem resistant (unlike the HD202s which over time peel), and the plastic materials (other than the cups) feel sturdy. Box also claims there are light weight. This is not BS, they are featherly. I do wished the headband was a bit wider for comfort, but not bad as it is. I have no problems fitting my ears inside the cups.
So wattabout the sound? Awesome. These provide quite a bit of impact and more than reasonable treble extension. Mids might be a little wonky relative to good open cans, but less so than many other much higher priced closed cans. Very open sounding, and don't seem to leak too much sound. There is warmth to these cans and definitively provide generous amounts of bass. IMO this does not get in the way. Liking "Gangsta's Paradise" by Robyn Adele Anderson on these:
Piano and wind instruments sound pretty clear and open to me. Original Gangsta's song sounds decent to me as well on these:Colio's Gangsta's Linky
(within watever youboobs limitations of course)
Given it's characteristics IMO these are great for movies as well. One of my fav tracks is "A Dark Knight" by Hans Zimmer and James Newton Howard, and these cans deliver."A Dark Knight" Linky
If you are into the Jazz-y side of things, I think "Old Love" below sounds a bit edgy and forward, but it could be more a function of the recording itself than the cans. For example, Nirvana's "Come as You Are" sounded K to me with these so that's that."Old Love" Linky
