Fostex / T50RP-BT

＜＜August 2026 New Product！＞＞The "T50RP-BT" is an RP wireless headphone that combines the identity of a monitor headphone—featuring excellent response, the ability to express subtle nuances, and spatial reproduction—with the convenience of wireless connectivity.

■ The first wireless model featuring RP drivers
・This is the first wireless model to incorporate RP drivers. Thanks to Qualcomm Snapdragon Sound™ and support for aptX™ Lossless and aptX™ Adaptive, you can enjoy high-quality audio at up to 24-bit/96kHz. Additionally, using the included USB-C transceiver for PC connections enables a low-latency connection of just 20ms. Combined with the superior transient characteristics unique to RP drivers, this wireless headset boasts the fastest response in the series' history.

■ Experience monitor-grade headphones with the fastest response—now wireless
・Based on the "T50RPmk4"—which features the fourth generation of Fostex’s proprietary "RP" (Regular Phase) full-drive planar diaphragm drivers used in professional music studios worldwide—this model has been converted to wireless. By combining the RP driver's superior response with Qualcomm Snapdragon Sound™, it inherits monitor-quality sound—reproducing precise imaging and soundstages across the entire frequency range—while freeing you from the hassle of cables. Enjoy a comfortable, stable, and low-latency experience whether listening on a smartphone at home or watching videos on a PC.

■ 4th Generation RP Drivers
・The RP technology full-drive planar diaphragm driver, refined in-house over 50 years, has evolved to its fourth generation. Improvements include an expanded diaphragm vibration area, increased magnet mass, and a new printed coil pattern. The magnetic circuit has also been completely redesigned to suppress unwanted diaphragm resonance and achieve sharp response. These enhancements simultaneously deliver improved sensitivity, smooth frequency response, and excellent transient characteristics. Accurate and delicate reproduction from deep bass to high treble further elevates the ability to recreate precise imaging and soundstages. As always, we ensure reliable quality through consistent in-house manufacturing.
*RP and RP Technology refer to Fostex’s proprietary technology (Patent No. 7675248) that drives the entire surface of a planar diaphragm with a regular phase. ■ Superior Responsiveness for Competitive Gaming
・ For PC gaming, the included USB-C transceiver ensures a stable connection with ultra-low latency (20ms). Combined with the exceptional responsiveness of the RP drivers, this headset delivers precise positional audio and sound separation—accurately pinpointing footsteps and target locations—to give you the competitive edge needed for victory.

■ Detachable Microphone Included
・ In addition to the built-in microphone, a detachable microphone is included for clear, comfortable voice chat. You can remove it when using the headset for casual listening and attach it when gaming or chatting.

■ Comfortable Ear Pads
・ The ear pads feature a memory-foam, circumaural (over-ear) design optimized for comfort. Paired with the traditional semi-open housing—which ensures adequate breathability—they allow for comfortable use during extended listening or gaming sessions. Optional ear pads made from Toray’s Ultrasuede (EX-EP-RP-SUEDE) are also available; these offer a soft, smooth texture that minimizes heat buildup while delivering high-quality sound across the entire spectrum, from rich bass to crisp highs.
