The GW100 are the worlds first open-back Bluetooth headphones. Their speaker housings and internals have been designed from the ground up, now working in tandem to notably diminish escaping sound by up to 60%.*
There is a design language that’s seen throughout all of our headphones since we started building them nearly 30 years ago. The GW100 continues this, looking like it’s part of the family simply at a glance. These wireless Grado headphones are a milestone in our 65 year history.
