Get This Price

For just $2290.99, down from its list price of $3699.99, this deal cuts $1409 off the standard price. The TH1100RPmk2 has held steady around $2500-$2800 over the past few months, so this drop to under $2300 marks a genuine low point.

If open-back planar headphones with this level of engineering are on your radar, now is the time to move.

What You're Getting

The TH1100RPmk2 is Fostex's latest flagship open-back headphone, built around 4th-generation RP (Regular Phase) planar drivers for high-resolution playback with low distortion and fast transient response. Double-layered aluminum apertures improve airflow for a wider, more detailed soundstage. The frame uses a lightweight magnesium alloy that cuts weight by roughly 20% compared to aluminum, and the redesigned Mk2 ear pads use a two-layer foam structure with silk-protein leather for a softer fit and better acoustic seal.

Who This Is For

Best for serious audiophiles and headphone collectors who want a flagship open-back planar without paying full flagship pricing. This is also a strong pick if you are upgrading from a mid-range planar set and want Fostex's latest driver tech.

Skip this if your budget tops out under $1000 or if you strictly listen on the go -- these are open-back, designed for a dedicated listening setup.

Final Verdict

At $2290.99. This is the lowest we have tracked on the TH1100RPmk2 since it hit the market. If you have been waiting for Fostex's top-tier planar sound to come down to earth, this price cut delivers.
