A Community Favorite, Now With Removable Cables

When the Massdrop community asked for a closed-back headphone that redefined price-to-performance expectations, the TH-X00 was our answer. Made in collaboration with Fostex, a brand that’s produced innovative audio gear since 1949, these headphones feature mahogany ear cups, a magnesium alloy frame, Fostex’s signature biodynamic drivers, and a highly reviewed sound signature. Now, in another response to the community’s requests, we’ve updated the original with a removable cable. Introducing the TR-X00 (the “R” stands for “removable”): everything you loved about the TH-X00, now with a detachable cable for greater flexibility. 

Note: This drop is limited to 150 units. The drop will end at 6303 total sold. Each pair of headphones is one of a kind, and due to the nature of wood, slight variations in wood grain may occur. If you’re an international customer looking to partner with a shipping forwarder, please read this FAQ.

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 TR-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 TH-600, 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.

Mahogany Cups, Comfort-First Design

The TR-X00’s mahogany ear cups 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 ear pads’ soft leatherette is designed to form a super tight seal, while still being breathable for hours of comfortable listening. And because the curve of the headband has been optimized to fit the human head, minimal padding is needed. The thick, braided cable has 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.

Community Reviews for the TH-X00 Mahogany

  • “These headphones were designed by audiophiles, and they’re glorious.” – The Verge
  •  “They are fun but can also be relaxing, and if you listen, the detail retrieval is incredible. Vocals shine through and the bass is elegantly presented. The midrange of the presentation that flows down to the bass are the two stars of your own show. Articulate, slightly weighty, but incessantly smooth … The entire sound signature is enthralling and worth a listen.” – moedawg140 on Head-Fi
