The 558 is a fine choice and you can mod them to sound similar to the 598 with a foam mod. The 558 and 598 use the same drivers just so you know.
As for the Symphonized brand you posted, I'm really unfamiliar with both the brand and that headphone. I tried looking but couldn't find a quality review on them, no good reviews and no bad reviews from my quick search. You aren't losing much if you want to try them out, just do more research on them to verify they are worthwhile.
