Fostex T50RP MK4G Plus - headphones with fourth-generation planar magnetic drivers and a detachable microphone. The basis of the headphones is the fourth-generation planar magnetic drivers, hence the MK4 prefix in the name. The first generation of this driver was released over 50 years ago, and since then this technology has been constantly improved. The latest version features an increased number of magnets, optimizing the shape of the magnetic field and a redesigned flat coil design to expand the vibration area of the flat diaphragm.
Fourth generation RP driver
This product is headphones 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 monitoring headphones. The fourth-generation RP headphones are the next generation of RP headphones, utilizing the traditional RP driver and a new housing design that further enhances the sound of the flat diaphragm.
The RP planar magnetic driver technology, first developed over 50 years ago and constantly refined over the years, is now presented in its fourth generation. A new coil shape was used to expand and align the vibration zone of the flat diaphragm. Additionally, the number of magnets connecting the membrane was significantly increased. Furthermore, the components of the magnetic circuit have been redesigned to optimize the magnetic flux distribution, suppress unwanted resonance, and achieve even better transient response.
The fourth-generation driver, developed using various technologies refined over many years, simultaneously provides increased sensitivity, smooth frequency response, and superior transient characteristics. Thanks to precise and delicate reproduction of elements across the frequency spectrum, the soundstage and localization have also been improved. The new driver is also more efficient, requiring less energy from the headphone amplifier to achieve maximum performance.
Balanced connection
Both the left and right housings are equipped with connectors for the included cable, so the cable can be connected from either the left or right side, depending on the operating conditions. Furthermore, due to the symmetric positioning of the left and right housings, the difference in sound characteristics, which usually arises from differences in the internal construction of the side panels, has been eliminated. The connector features a 3.5mm 4-pole connector that supports balanced connections, enhancing ease of use and versatility. High-quality OFC conductors are used in the cable.
Comfortable earpads
The new, thicker earpads have low resilience and snugly fit the ear, providing a comfortable fit, making them comfortable to use even during long listening sessions.
Optimized for gamers
Fine-tuning for quick response in the important mid-frequency range allows FPS gamers to hear opponents without delays or distortions inherent in 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. Thanks to the 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.
