Ehh ebay used headphones aren't for me. I would only buy used headphones from HF because everyone is awesome 
Honestly, I don't know if it's a good deal or not because I'm not familiar with the Euro and hearing it's 1 year old, you just never know. However, seeing how it's re-cabled and it's Denon, there shouldn't be much wrong with it? Just hope it was worth the price.
