Up for sale is my Beyerdynamic DT250 headphone. I bought these recently after auditioning my friend's pair of DT250. However, I changed my mind and decided to upgrade my portable audio setup instead, so these are still brand new. This headphone is made in Germany and is a closed back, sealed design that fits around your ears. The comfort is excellent and the sound quality better than the DT770 in my opinnion. The impedance rating is 250 ohms. Price is $120 picked up in Toronto, Canada. Shipping and paypal fees extra.
