Look you dont have to go cheap to get great sound with the proper connection you want, I would recommend Grado Labs headphones.

Recommendation for Headphones under $250
I'm looking for recommendations for a cheap and cheerful headphone to plug into my digital piano (1/4" plug) for silent piano practices! I don't want to do a ton of research (like I normally do!), so I would appreciate any best bang for the buck recommendations. Thank you in advance!
