Visually defined by large Norwegian pine wood housings, the limited edition Grado Heritage Series GH4 are over-ear headphones designed to communicate a warm tone and wideband frequency reproduction for audiophiles and music enthusiasts in homes, listening rooms, and acoustically controlled environments. The open-back design reduces internal resonance and reflections to enhance transparency. The 44mm dynamic drivers are matched to 0.05 dB and produce a wide frequency response of 18 Hz to 24 kHz. With a 32-Ohm impedance, the GH4 headphones are well suited for use with mobile devices as well as dedicated headphone amplifiers.

The cushioned earpads and headband ensure comfort for long listening sessions. The full-sized earcup housings feature a larger cut of Norwegian pine than the lower-profile GH3 model, and the extra wood gives them an even richer, warmer tonality. The 5.9' hardwired cable is terminated with a 3.5mm TRS connector for compatibility with mobile devices and computers, and the supplied gold-plated 1/4" adapter allows easy hookup to audio interfaces, mixers, and separate amps.
