Fostex TH-X00 Mahogany - Massdrop exclusive, Gently Used

Fostex x Massdrop TH-X00 Headphones

Available exclusively on Massdrop, the Fostex x Massdrop TH-X00 Headphones were born of a collaboration with a brand that’s brought us innovative products since 1949, in response to our Audiophile Community’s call for a price-to-performance redefining closed-back headphone. Featuring mahogany ear cups, a magnesium alloy frame, Fostex’s signature biodynamic drivers, and a highly reviewed sound signature, the TH-X00 fills that mandate.

Improved Technology, Intimate Sound

Equipped with the biodynamic cone Fostex first developed in the late ‘80s, which delivers a sound unique to any other driver structure, the TH-X00 benefits from years of iterating on that original design. The higher magnetic flux density in these headphones (more than 1 tesla) creates instant attack and decay for a crisper, more detailed sound signature.

With the emphasis on the low end toned down slightly from the TH600, the rich bass meets the Fostex standard without becoming bloated. The top end’s been taken down several decibels, too, neutralizing any sharp, sibilant highs and putting the emphasis on the mids. The result is an incredibly intimate sound, like being front row at a small venue, and performs exceptionally well with the nuanced harmonies of Imogen Heap’s “Hide and Seek” and the haunting vocals in Bright Eyes’ “Lua.”

Mahogany Cups, Comfort-First Design

The TH-X00’s mahogany earcups are a nod to the Denon D series (though somewhat lighter in color and more luminescent) and complemented by Fostex’s proprietary magnesium alloy body, built to be lightweight, strong, and durable. Made of eggshell protein, the earpads’ soft leatherette is designed to form a super tight seal, while still being breathable (real leather does not breathe) for hours of comfortable listening. And because the curve of the headband has been optimized to fit the human head, minimal padding is needed for you to forget you’re wearing headphones at all.

A thick, braided cable rounds out the presentation, with a conveniently long distance between the headphones and Y split. The Massdrop logo is silk-screened on the inside of the headband, just above the left cup, with a serial number located just above the right cup.
