The Denon AH-D510R are over-ear closed headphones with a 3-button remote and mic made to be used with iPhone, iPod and iPad. The D510R are priced at $99.99 and are one of Denon's affordable headphone offerings. It's no surprise that Denon specialize in audio products so my hopes were high for the D510R and that they would without a doubt sound great. Right out of the box? Not so good. I've spent some good quality time with the D510R before giving my final thoughts about them in this review. Catch the full review right after the break.
