For general use should i buy Skullcandy smokin buds (Or I'NKD) headphones or Sennheiser CX500 ones?

I've used both the smokin buds and I'NKD headphones. They both have great sound quality, but I prefer the Smokin Buds only for their in-line volume. It's really convenient if you don't want to dig out your iPod to raise or lower the volume.
