Expert Reviews

Freshly arrived on my review desk, the PreSonus HD9 comes from a company renowned for its audio interfaces. This headphone sports a classic design that mirrors the highly-successful ATH-M50. But how does it sound? And at a modest $79, is there any reason not to lap up the Kool-Aid?
User Reviews
Fabulous product and improvements on HD7
Proves you don't have to spend $500+ for a fantastic set of studio monitoring headphones. A few years back I ponied up a lot of cash for a pair of Beats Studio phones thinking they were going to be a great set of reference phones. Boy, do they suck compared to these.
