Fostex has introduced the T50RPmk4CL and T60RPmk2CL closed-back planar headphones, designed for both music production and listening pleasure.

Innovative Design

These headphones feature the latest fourth generation RP Series Driver, which is a patent-pending innovation. It employs a more dense coil pattern and a unique magnetic structure, which enhances the push-pull force acting on the diaphragm. The T50RPmk4CL resembles the semi-open-back T50RPmk4 but has a closed-back structure and weighs 330 g (11.6 oz.). On the other hand, the T60RPmk2CL is crafted from black walnut wood for its ear cup housing, also presenting a closed-back design, but slightly heavier at 360 g (12.7 oz.).

Performance Specifications

The RP driver achieves a frequency response ranging from 10 Hz to 40 kHz, with a sensitivity of 97 dB/mW. The headphones boast an impedance of 28 ohms and can handle a maximum input power of 3,000 mW. Their thick ear pads have an angled design, enhancing the sound staging experience. For those looking for added comfort, optional Toray Ultrasuede ear pads are available, providing breathability and a softer feel.

Accessories and Availability

Included with the headphones is a 2 m (6.6 ft.) 3.5 mm-to-3.5 mm (1/8-inch-to-1/8-inch) cable, along with a 3.5 mm-to-6.3 mm (1/8-inch-to-1/4-inch) adapter. The oxygen-free copper (OFC) cable can be plugged into either side of the T50RPmk4CL for ease of use, while the T60RPmk2CL features a Y-cable that connects to both sides.

The release date for both headphone models is set for July. Although pricing details haven’t been revealed yet, it is anticipated that the lower-end model will start at around $250.

If you’re in search of Fostex headphones that offer a broader soundstage than these closed-back options, consider exploring the semi-open-back Fostex headphones available on Amazon.
