PreSonus HD9 Closed-Back Headphones Combine Comfort and Wide Frequency Response
PreSonus is shipping its new HD9 headphones, designed for studio use, as powerful and articulate studio monitors. The new headphones feature a closed-back acoustic design that provides superior listening isolation and reduces headphone bleed, so users hear nothing but music. The HD9’s 45 mm dynamic, neodymium drivers and high power handling (900 mW per channel into 40Ω) deliver loud, clean audio, minimizing listening fatigue. Its tailored frequency response extends all the way from 10 Hz to 26 kHz (±3 dB), with accurate bass response.
