In noise cancel mode, these headphones sound great. They have a flat response and sound very natural. The highs are not too crispy and the lows are not too boomy. They block out external mid and high range noise effectively, though some lows might creep in and you cannot use noise cancel in the wind. They sound awful with the noise cancel off and are useless in that mode. I drive a diesel truck and I have no regrets at buying these headphones. They have soft pads and are lightweight and comfortable and I very much appreciate the sound quality. I found Phillips earbuds to be way too crispy in the high end and returned a set of Koss QZPRO because they sounded terrible.If you are looking for good sound in a noisy environment, these Sony's will do you good.
