Bought the Philips Shl3300 Dj Headphone from Kalahari for about R240. Same thing sells for R500 at Dion Wired. Music clarity is great and bass is deep. Moving up higher I would skip the Sen's and move up to JBL Sync 300 as those have built-in amplifier.

You could have gotten 10% off the takealot price at Dion wired if you'd shown them the link.
