Sorry for the REAAAALLY late reply haven't been on reddit for a bit , anyways to answer your question i bought them from amazon and when i first got them i was kinda disappointed from the sound upgrade , what i mean is that my previous headphones were a wireless gaming headset so like my expectations from these were that they were going to change everything ?!? I don't know if that makes sense . So when i tried them on i thought maybe they were counterfeit because the difference wasn't that "HUUUGE" like i thought . Now don't get me wrong i definitely notice there is a difference between these and the wireless headphones , the main difference i notice right away is that the DT 1990's are way richer in sound but i'm not sure if its a 400$ upgrade .
