Pioneer Announces the New HRM-7 Professional Reference Monitor Headphones!



HRM-7 Studio Headphones Built for Sound and Comfort

LONG BEACH, Calif. (January 21, 2015) – Pioneer Electronics (USA) Inc.’s Professional Sound and Visual Division today introduced the HRM-7 studio headphones intended for home and private studio listening, providing excellent audio reproduction with maximum comfort.  Pioneer’s latest headphones incorporate a newly developed HD driver suited for high-resolution audio sources and capable of reproducing frequencies up to 40 kHz.  Its “dual chamber” bass reflex enclosure also helps produce lower bass response as well as provide better control for increased audio accuracy.  The incorporated hybrid memory-foam ear pads provide a snug fit around the ears and maximum comfort when worn for extended listening sessions. 

“We wanted to design studio headphones that feel as good as they sound,” said David Arevalo, director, Professional Sound and Visual Division for Pioneer Electronics (USA) Inc. “The HRM-7 delivers rich and powerful sound ideal for a professional type of listening, whether at home or in a studio.  These headphones have a natural response ideal for all types of music listening including high resolution audio. ”   

Large HD Driver

The large 40 millimeter HD driver combined with a copper-clad aluminum wire (CCAW) voice coil and neodymium magnets built into the HRM-7 produce outstanding audio playback and great sound localization.  The new HD driver along with its strong magnet structure can reproduce a very wide frequency response from 5 Hz to 40 kHz, ideal for all types of music listening including high-resolution audio files. 

Dual Chamber Bass Reflex Enclosure

Pioneer developed a dual chamber bass reflex enclosure to enable the headphones to generate lower bass frequencies while still maintaining great control of the HD driver for increased audio accuracy.  The sound isolating dual chamber (air chamber) prevents outside noise from affecting the enclosure, essentially increasing bass response while the integrated ports enhance the efficiency of the driver.  The housing (enclosure) is further reinforced by a 3-layer damping structure, suppressing vibrations and unwanted resonance, resulting in improved audio response out of the HD driver.

Large Housing and Comfortable Ear pads

The housing of the HRM-7 creates a large listening chamber to produce a wide sound field for better sound localization. Wrapped around the housings are full-sized hybrid memory foam ear pads, that feel extremely comfortable, even when worn for long periods of time.  Furthermore, the memory foam ear pads are covered with soft velour that contours around the ears to help reduce exterior sounds entering the listening chamber. 

Designed to Fit

The 3D ergonomic design further optimizes the angled fit of the ear pads around the head while the free adjust head cushion helps produce a snug fit across the entire head without creating uncomfortable force. 

Additional Features:

  • Detachable 1.2 m curled and 3 m straight cables using Oxygen-Free Copper (OFC) litz wire
  • Replacement velour ear pads
  • Gold plated 6.3 mm stereo plug adapter 

The Pioneer HRM-7 will be available in March with a suggested retail price of $239 USD.
