Wireless Series GW100x headphones
The GW100x builds on Grado's first wireless headphone with Bluetooth 5.2, a longer battery and new X drivers. Nothing is lost except the wires.
Materiality of sound
Grado has been refining sonic reproduction since 1953. The GW100x brings that heritage to wireless listening, aiming to deliver an honest texture to your music.

Two days to tune out
Bluetooth 5.2 and a more efficient battery let the GW100x play for nearly two days straight. USB-C charging brings it in line with global standards, and the upgraded chipset maintains a strong connection while passing more information from your device to the headphones.
X Series driver
Grado's 4th-generation 44 mm drivers are tuned specifically for the GW100x. A more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm together improve efficiency, reduce distortion and preserve harmonic integrity.
Milestone after milestone
The GW100 was the world's first open-back Bluetooth headphone. Its housings and internals are designed from the ground up to reduce escaping sound by up to 60%. The GW100x continues Grado's design language — recognisable as part of the family at a glance — and marks another milestone in the brand's seven-decade history.
Music, voice, volume, calls
Control volume, music playback, calls and your voice assistant directly from the headphones, no need to reach for your phone. The mic and remote are built in and work with compatible devices.

From our tech experts at CEN
Grado headphones, wireless, still hand-assembled in the family workshop in Brooklyn.
Who it suits
Listeners who have outgrown what came with their phone and want something with genuine personality rather than a flat, safe tuning. Grado’s sound is forward and direct, which people tend to love or find too much.
Our tech experts advise
Source quality matters more than most people expect: good headphones reveal a weak source rather than covering for it, so a DAC or player is usually the next step. get in touch for a recommendation.
