This is the lowest price on record for the mk4 generation. The 30-day average sits at $249.97, and the 90-day average is $249.98, so this $244.99 price is a genuine bottom, not a marketing swing.

If you've been waiting on the T50RP line's fourth-gen refresh. This is the cheapest entry point yet.

What You're Getting

The mk4 is built around Fostex's completely redesigned RP planar magnetic driver, the core technology that gives these cans their signature detail retrieval and headroom. The connector uses a 4-pole 3.5mm jack that supports balanced connections, giving you more flexibility with amps and DACs.

Fostex wired the cable with high-quality OFC conductors to keep signal loss minimal. The new thicker ear pads use a low-resilience, around-ear foam that stays comfortable during long listening sessions, a meaningful upgrade over previous generations.

Who This Is For

Best for: audiophiles on a budget who want planar magnetic sound without spending $500+. The T50RP mk4 is a staple recommendation for anyone building a first serious headphone rig, especially if you already own or plan to buy a dedicated amp.

Skip this if you need closed-back isolation or a portable set for commuting, these are open-back studio-style headphones that want a quiet listening environment.

Final Verdict

The mk4 is the best version of Fostex's legendary T50RP design, and at $244.99 it's the cheapest that version has ever been. If you need planar headphones for critical listening or mixing. This is the price to act on.
