Thanks for answering
well i can't find shure to buy in local store, i should get them from ebay. but i can buy creative at shop nearby me. what do you mean by saying pure sound? which cans you think have more bass / deeper mids? (i don't think highs are very important in electronic music, or am i wrong?) and how the CAL perform in games? and i found some more at my price (i haven't found almost any info about these in this forum): audio technica ath-t500, sennheiser 429/449(i read that older generation 448 was more for clasical music, so probably i'll just skip this)
For your reference, I'm primarily a U.S. roots music guy, covering from blue grass, rockabilly, country to blues with a heavy emphasis on early and classic rock. I generally use a Senn HD 437 with my computer for all purposes, including games. But almost all my music is on CD and vinyl. I have only used the CAL and Shure with CDs and HD radio.
The CAL just do everything well for their price range--frequency response high to low, clarity, balance and a sweet sound. They are a slightly improved clone of the much loved Denon AH-D1001. They are the best sub entry level audiophile level phone of which I know.
The Shure srh440 is designed for the studio and is better at being analytical, but less good at music enjoyment.
