They are available whilst stock last only so grab a bargain whilst you can.


Inside the GW100 are none other than the signature Grado drivers. These speakers are the same ones they build for their wired headphones, which are finely tuned for the different enclosures they use.

Grado Labs' first wireless headphone is no different, with drivers configured specifically for them. The desired sonic capabilities of the GW100 would not be possible without decades of experience in driver design.

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%.*

GW100 Wireless Series

There is a design language that’s seen throughout all of their headphones since they 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 their 65 year history.
