The first and only open-back Bluetooth headphone on the market. No compromises… it's a Grado®. The GW100 is the first Grado wireless headphone, featuring Bluetooth® technology. More than 25 years of experience designing the world's finest headphones naturally lead Grado Labs to developing the only open-back, Bluetooth headphone on the market.

Grado's legendary driver technology, Bluetooth, padded headband, 15 hour battery life, and a lightweight comfortable design make them perfect for today's portable lifestyle.
