The Sennheiser CX880 are about 55 USD on Amazon. I'd say those are the best you can get within your pricerange, but tbf the difference in quality isn't enough to justify the 20 bucks extra compared to the CX300's. I use the 300's for public transport and they get the job done, pretty sturdy headphone too.

We should both save up for a pair of Shure E2c's though
People who don't know how to use the internet are getting fucked with no lube these days. No wonder stores are going down everywhere, they charge three times what the product's actual worth is. I got my HD550 for 150EU back in the day over the internet, the price in the store was 320EU.
Definitely, that happened to many stores over here but just about most now have some kind of online store. That store's prices are usually pretty competitive, suprised of the difference there. They are probably the biggest and most popular retailer of home enterntainment electronics, music, games etc in Australia.
