For just $1876.33, below its 30-day average of $2011.40. That 30-day mark skews low compared with the 90-day average of $2253.62 and the 180-day figure of $2472.75, so this is one of the better entry points in recent memory. The all-time low sits at $1755.09, but with the list price at $3699.99, current pricing still represents a meaningful gap from sticker.

What You're Getting

This is Fostex's 4th-generation RP planar driver design, built for low distortion and fast transient response. Key specs:

- Open-back flagship design engineered for an expansive, natural soundstage

- 4th-generation RP planar drivers with high-resolution playback

- Double-layered aluminum apertures that manage airflow for a wider, more detailed presentation

- Lightweight magnesium alloy frame that trims roughly 20% off the weight versus aluminum

- Redesigned Mk2 ear pads with a two-layer foam structure and silk-protein leather for a softer fit and refined acoustic seal

Who This Is For

This is for serious listeners pairing a quality DAC or amp with a reference-grade open-back. The magnesium frame and improved pads make it a workable daily driver for long listening sessions, not just a showpiece.

If your chain can't push a demanding planar, hold off until your sources catch up.

The Caveat

It is an open-back design, so it leaks sound and lets ambient noise in. Not the pick for a shared office or commutes, and the all-time low of $1755.09 shows this price can go lower if you can wait.

Final Verdict

If you want Fostex's top-tier planar tuning now and the sub-$1900 zone works for your budget. This is the price to move on. The magnesium frame and silk-leather Mk2 pads alone justify the premium over cheaper planars.
