T50RPmk4g+
Gaming HeadsetRP Technology headphones with the fastest response ever, plus a dedicated microphone
Revolutionizing the Gaming Experience
The T50RPmk4g+ revolutionizes gaming experiences with RP technology, adding a dedicated microphone to the T50RPmk4g and featuring the 4th generation RP planar diaphragm driver that faithfully reproduces instantaneous sound contours with excellent transient characteristics, boasting the fastest response in history for a gaming headset. With a microphone that can be connected to either the left or right side, it enables comfortable voice chat, providing a gaming environment that brings you even closer to victory.
*RP and RP Technology refer to Fostex's proprietary technology (patent pending, application no. 23054P-JP 2024-054367) that drives the entire surface of a planar diaphragm with a regular phase.
Specifications and appearance are subject to change without notice for product improvement.

RP History Video
Features
Fastest ever overwhelming response speed enables excellent localization and separation
The RP technology planar diaphragm driver, which has been improved over the past 50 years and evolved into the fourth generation, has undergone significant improvements, including an increase in the number of magnets that sandwich the diaphragm and a new design for the pat-tern shape of the printed coil. This enables accurate and high-definition reproduction from the low to high frequency range, and delivers an outstanding sense of localization and separation with overwhelming response. This presents a distinct advantage in hearing minute sounds like footsteps, quickly and accurately locating them, and pinpointing and clearly distinguishing targets against environmental sounds and background music.

Dedicated microphone that can be connected to either left or right for comfortable voice chat
The dedicated microphone can be connected to either the left or right side according to your gaming environment, allowing for comfortable voice chat. The controller on the microphone cable enables microphone mute ON/OFF and volume adjustment. Additionally, by using the same shape for both the left and right housing, we reduce sound quality differences caused by internal left-right variations due to the presence or absence of connectors, resulting in clearer sound positioning.



Semi-open housing and memory foam ear pads allow for comfortable play for extended period
The semi-open housing design provides adequate ventilation and clear sound quality with re-duced stuffiness, while the around-ear memory foam ear pads ensure comfortable wear. This combination prevents heat buildup during extended gaming sessions, allowing for comfortable use over long periods.
