I Bought a pair of MX500 headphones from Jason. They had a problem with the volume control, that Jason didn't know about. He refunded me half of purchase price, that both sides would be satisfied. Good Head-fier, and would do business again.
Bought an iRiver iHP-120 from Jason. He responded ultra fast, kept in touch, shipped even faster, and in general everything went very well. Will definitely do business again if the opportunity is there. Thumbs up for a good seller!
