This did remind me, IDK where you live but if it's the US, there is always the Headphone Library.
The Cable Company has a library for cables, and they did expand it for headphones as well. Basically you pay shipping (both ways) & 5% of the value, but the 5% is refundable toward ANY purchase on their website.
Not fantastic, but definitely not outrageous either, and a good option if you have nowhere to demo (they do stock Mr. Speakers, Audeze and a few others as well). I always wonder why more companies don't try something like this.
Anyway here's the more detailed description:
