It was high time Audioholics picked up the ball and did some headphone reviews, so we contacted a few manufacturers and selected some products based on price and specifications that we thought would represent a more mainstream target for price-to-performance. Ultrasone’s $399 PROline 750 headphones seemed to fit the bill and we quickly arranged for a pair to be sent to us.
