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 released our first one in 1991. 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 over seven decade history.

Our first true wireless in-ears, the GT220 mark a milestone in our seven decades of audio. Years in the making, we didn’t want to rush the process of creating a compact and versatile wireless Grado headphone with such vocality and depth. Control music, calls, and more with just a tap, or your voice with the built-in microphone. Easy to always have around, they’re ready when you are.
