Grado GH2 (Heritage Series Limited Edition)

The Grado GH2 is a limited-edition, open-back headphone from Grado's Heritage Series, and the record on it is thinner than a headphone with this much character deserves. What is documented is genuine, though: it is a dynamic, open-air design built around a special air chamber machined from cocobolo wood — a dense, richly grained tropical hardwood that gives the model its identity. The GH2 was widely enough regarded that reviewers dubbed it "The Cocobolo Audio Machine," and Grado positioned it as a premium audiophile offering.

Known specifications are scarce but solid:

Transducer type: dynamic
Operating principle: open air
Frequency response: 14 – 28,000 Hz
SPL 1 mW: 99.8 dB
Nominal impedance: 32 ohms

Not documented anywhere I could find: the original price, production years, driver size, cable specs, and weight. For a limited-edition model, that missing history is a real gap — but the cocobolo chamber, the heritage-series placement, and those five specs are the honest core of what the GH2 is known for.
