The Pioneer HRM-7 Headphones are a brand new addition to Pioneers prestigious headphone line up that cater directly to studio referencing and monitoring with their 40mm HD drivers and large enclosure design. Designed with producers in mind the HRM-7 Headphones have a vast frequency response of 5 – 40000 Hz and also feature a fully adjustable headband and memory foam ear cups to ensure maximum comfort during extended use. Large HD Drivers The large 40 millimetre HD driver combined with a copper-clad aluminium 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.
