Grado GS3000x
Open-back Grado GS3000x headphones with a Cocobolo wood housing, fitted with a 50 mm dynamic transducer, for stereo listening at home.
Description
The GS3000x is an open-back headphone designed by Grado Labs, featuring a Cocobolo wood housing. It belongs to the Statement Series, the brand's most accomplished range in terms of solid wood housings.
Its 50 mm dynamic transducer is tuned to make the most of the acoustic properties of Cocobolo, a wood originating from Central America already used on other models from the brand such as the GH2 or certain high-end cartridges. The frequency response spans from 4 Hz to 51,000 Hz, with a sensitivity of 99.8 dB SPL for 1 mW and a nominal impedance of 32 ohms.
An impedance of 32 ohms combined with this sensitivity allows use with a headphone amplifier or a moderate-power source, without necessarily requiring an oversized amplification stage.
These headphones are aimed at home stereo listening enthusiasts seeking an open-back headphone with a tonal character shaped by its housing material, for sedentary rather than portable use, the open-back design letting ambient sound pass through and vice versa.

What to check before buying used
On these open-back headphones, the foam ear pads in Cocobolo are the first to wear: check that they are not compressed, cracked or coming away, as they determine the acoustic seal for the bass. Also inspect the headband and suspension for any play or cracks, and examine the solid wood housing for splits, chips or signs of impact, as this material is sensitive to changes in humidity. Finally, check the continuity of the cable and the solder joints at the jack plugs.
