I bought these a couple months ago from JB HIFI to use with my iphone. I thought I'd use them last night while riding. Only had the volume a little past half way and the sound was great riding at 100km/hr. They also cancel out a lot of the wind/road noise. If you need to turn the music off in a hurry, just pull the jack out of your music player Good option for those who can't fork out hundreds for noise cancelling headphones. The sound quality is great, crisp and just the right amount of bass. I can't remember the exact price but I think it was around $70-$80.
