I was just wondering what your advice is on something. So I bought Pioneer se mj591 from amazon for $ 193 dollars from a seller that was a little sketchy. The headphones were supposed to cost $299. When I got them in the mail they accidentally sent me Audio Technica ATH ESW9 which are worth $369. What my question is, Do you think I lucked out my getting sent the Audio Technicas or would the Pioneer headphone sound better? I listen to many different types of music and my Laptop or android phone are my main sources. I have been listing to the Audio technica headphones all day and they sound pretty good almost as good as my Beyerdynamic DT 770s but I was just wondering if you think I should keep the ones I got or should I return them and get the other ones?
