If you can stretch to $50 I think it will be hard to beat the Takstar Pro80 for a closed can at that pricepoint. You can get them for $48 including shipping from Ugomark (shipping might be a little higher than stated but should not add more than $5 extra). If you're in North America you could aslo check out the Gemini HSR1000 wich is a rebrand of the same headphone.
Can't actually find them under 67$ on Ugomark and I'm european, not NA. What if I would want to pay less, tho? Is there another choice for me? :) Thanks!
EDIT: Derp, I didn't sort it by price, but by popularity. So there's quite a few Pro80s around the 40$ price mark. Are they worth a shot or do you think they might be fakes with different sound? (as some of the Pistons)
