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 - The Grado GW100.

Some might think wireless and open-back are an odd pairing, but now you can enjoy audiophile quality sound untethered. Whether you’re fly-fishing or just cleaning the gutters, you don’t want wires dangling. But you do want awesome Grado sound. Grado’s legendary driver technology, Bluetooth, padded headband, 15 hour battery life, built-in microphone for calls, and a lightweight comfortable design make them perfect for today’s portable lifestyle. The large soundstage and detail only available from an open-back design, plus Bluetooth, coalesces into the perfect wireless headphone.
