PRESENTING RAAL REQUISITE SR1a - WORLD'S FIRST EARFIELD MONITOR HEADPHONE

The team at RAAL-requisite presents the technologically advanced SR1a Earfield headphone monitor. The SR1a by RAAL-requisite is the world’s first Earfield™ headphone monitor. Experience mixing, mastering, and home listening with unparalleled accuracy and realism in a sound field devoid of room acoustics and comb-filtering caused by work surface reflections. Earfield™ technology delivers unheard-of program accuracy and a speaker-like sound field experience.

ONE OF ITS KIND TRUE RIBBON HEADPHONES WITH SPECIALISED RIBBON DRIVERS

The RAAL-requisite SR1a headphones are embedded with the latest and cutting edge technology in the audio field. This innovative approach is reflected in the driver configuration and the type of driver selected for the headphones. The SR1a is the world’s first True-Ribbon™ headphones and have been equipped with highly specialised ribbon drivers that reproduce 30Hz to 30kHz bandwidth to eliminate the need for sealed chambered bass and allow for open-air baffles (both front and back) for a full-frequency sound field.

DELIVERING SUPERIOR ACCURACY AND DETAILED AUDIO WITH INCREDIBLE COMFORT

Professional engineers and discerning audiophiles report that the RAAL-requisite SR1a Earfield Monitors™ reveal more detail and accuracy than even their finest traditional studio monitors or headphones. The accuracy, musicality and portability of the SR1a headphones allow the engineer and the audio enthusiasts to work and listen to music whenever and wherever they choose. Unlike standard headphones whose weight and heat create discomfort over time. The RAAL-requisite SR1a Earfield design eliminates heat buildup on the ears providing a cool, natural airflow. SR1a headphones can be worn comfortably for hours at any listening level.

HAND-BUILT EXCLUSIVELY BY SKILLED CRAFTSMEN WITH THE FINEST MATERIALS

The RAAL-requisite SR1a headphones feature the finest materials for every component of the headphones. The RAAL-requisite SR1a features carbon fibre baffles, stainless spring steel headband, aluminium ribbon drivers, plush memory foam bars, and lambskin leather (non-leather option available) for a luxurious feel. Every SR1a headphone is expertly handmade and assembled in Serbia by skilled European craftspeople who build world-renowned RAAL ribbon tweeters.

UNLOCK THE TRUE POTENTIAL OF THE SR1a HEADPHONES WITH INTERFACE OPTIONS ​

The RAAL-requisite SR1a is not a standard headphone and will not work on most conventional headphone amplifiers. There are currently 2 different ways to connect and drive these headphones - a special ribbon amplifier or the interface box with a speaker amp. The SR1a interface box converts a typical speaker amplifier output into the load characteristic that the headphones require. Connect your speaker amplifier to the interface via speaker cables and plug the SR1a into the 4-pin XLR connection on the front of the interface box.

We currently offer four customised packages for your RAAL-requisite SR1a Headphone.
