Sennheiser HD 598's (Usually $300, now $242) The 558's are actually more expensive at the moment at $255 lol
Headphones are usually significantly more expensive in Canada.
Canadians do not have it easy with this little hobby. Buying online from American sources is never any better either because the shipping ends up evening out the smaller price tag, not to mention the possibility of paying duties.
You can easily expect to spend $100 more on any mid fi headphone in Canada.
Pulse 40W Active Two-Way Speaker Pair with 5" Woofers - Black $60 Might need a sub to go along with them. Wall mounts included.
edit. They're only different in the size of the holes in the grills and the foam padding between the grill and the driver. I think the grill is placed in a slightly different angle on the 598, but thats about it construction wise.
