this be my very first pair of over-20-bucks-headphone . I be very impressed with the sound quality , it be really great . the price be totally worth it . the case be big enough even to carry my zune , the headphone sound great , loud and clear in every single note . I listen to a lot of soundtrack and trailer music that be mostly orchestral or simply instrumental with very rich sound and i have make sure to challenge this earphone to the max . they have not fail . very happy so far .
