The Fostex T50RP MK4G Plus headphones feature fourth-generation planar magnetic drivers with a detachable microphone. The basis of these headphones is the fourth-generation planar magnetic drivers, indicated by the MK4 in the name. The first generation of these drivers was released over 50 years ago, and since then this technology has been continuously improved. The latest version features an increased number of magnets, optimizing the magnetic field shape. The design of the flat coil has been changed to expand the vibration zone of the flat diaphragm.
Fourth Generation RP Driver
These headphones are equipped with a significantly updated RP driver with a flat diaphragm, controlled by a full field, originally developed by Fostex. RP drivers have been used in various models and have been recognized by musicians and studio engineers worldwide as monitor headphones. The fourth-generation RP headphones represent the next generation of RP headphones, using the traditional RP driver and a new housing design that further enhances the sound of the flat diaphragm.
Planar Magnetic RP Drive Technology
The planar magnetic RP drive technology, first developed over 50 years ago and continuously perfected over the years, is now presented in its fourth generation. A new coil shape has been used to expand and align the vibration zone of the flat diaphragm. Additionally, the number of magnets connecting the membrane has been significantly increased. The magnetic circuit components have been redesigned to optimize the magnetic flux distribution, suppress unwanted resonance, and achieve even better transient response.
Balanced Connection
Both the left and right housings are equipped with connectors for connecting the included cable, allowing the cable to be connected from either the left or right side, depending on the operating conditions. The symmetrical placement of the left and right housings eliminates differences in sound characteristics that typically arise from variations in the internal construction of side panels. The connector features a 3.5mm 4-pole connector that supports balanced connections, enhancing ease of use and versatility. The cable uses high-quality OFC conductors.
Comfortable Earpads
The new, thicker earpads have low elasticity and fit snugly around the ears, providing comfortable wear even during extended listening sessions.
Optimized for Gaming Enthusiasts
Fine-tuning of the quick response in the important mid-frequency range allows shooter game players to hear opponents without delays or distortions typically associated with classic gaming headsets. The fourth-generation RP flat diaphragm driver accurately reproduces instant sound contours with superior dynamic characteristics, offering the fastest response in gaming headset history. With a microphone that can be connected from either the left or right side, it provides convenient voice chat, creating a gaming environment that brings you closer to victory.
