Special Collaboration in Purpleheart

In response to the audiophile community’s call for a D5000 successor at a comparable price, we teamed up with Fostex to create the TH-X00 headphones in 2015. Then, based on the success of the first version, we decided to make a new iteration—this time with purpleheart earcups in place of the original mahogany. Purpleheart is among the densest woods in the world. Along with adding a darker, more sophisticated aesthetic, these deliver a slightly different sound signature.

Note: Each pair of headphones is one of a kind, and due to the nature of handwork, slight variations in wood grain may occur. If you're an international customer looking to partner with a shipping forwarder, please read this FAQ.

Jude's Review on Head-Fi TV (Original TH-X00)

A Side-by-Side Look

The density of purpleheart wood makes it excellent for reducing acoustic resonance. As a result, the sub-bass through bass is increased ~2 dB, while following the same curve as the original, which peaks at 50 Hz. The lower midrange is decreased by ~5 dB, and while the mahogany version had a slight peak at ~600 Hz, the purpleheart has a smoother climb from 500 to 1000 Hz. The midrange proper is essentially identical to that of the mahogany, the upper midrange is ~2 dB less throughout, and the highs are slightly more emphasized. Peaks and valleys are positioned differently than on the mahogany, but their magnitude is similar. As for the super highs, while the mahogany falls off at ~14 kHz, the purpleheart maintains presence through that range. Finally, CSD graphs of the mahogany showed some resonance at 3,000 and 6,000 Hz; these are all but eliminated in the purpleheart.

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 iteration on the initial 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 result is an incredibly intimate sound, like being front row at a small venue.

Comfort-First Design

The TH-X00’s wood earcups are a nod to the Denon D series 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 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.

Additional Details

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.
