If you are looking for heavy bass with loudness, then this probably will not be the best one for you.
Coming to the Design: And yes since the whole ear gets covered by the earpads, ear will get heated up frequently. One more of my personal grudge is the size and look of the Headphone.
In Summary, This Headphones offer good sound quality. The design might be not so good but in this price Range, this is a great product.
