Grado GW100x

The Grado GW100x represents a bold evolution in the world of audiophile headphones. This model combines Grado’s legendary sound signature with the freedom of wireless technology, while maintaining a unique open-back design. As the successor to the GW100, it brings significant improvements in battery life and Bluetooth technology, without compromising on audio quality.

A revolution in the wireless world

The GW100x stands out with its open-back design, a rarity in the world of Bluetooth headphones. This daring approach delivers a wider and more natural soundstage while retaining the benefits of wireless mobility. Grado has met the technical challenge by reducing sound leakage by 60% compared to a traditional open-back headphone, making the GW100x more versatile than its predecessors.

This technical achievement allows audiophiles to enjoy high-quality sound without being burdened by cables, while preserving Grado’s characteristic sound signature. The GW100x strikes a subtle balance between sound openness and discretion, making it suitable for a variety of listening environments.

Uncompromising sound quality

At the heart of the GW100x are Grado’s new 4th-generation 44mm dynamic drivers. These speakers, specifically designed for the GW100x, feature a more powerful magnetic circuit, a reduced-mass voice coil, and a reconfigured diaphragm. This advanced engineering results in notable improvements in efficiency, reduced distortion, and enhanced preservation of the music’s harmonic integrity.

Sound precision is further enhanced by matching the drivers to within 0.1 dB, ensuring perfect balance between the two ears. This meticulous attention to detail allows the GW100x to reproduce every musical nuance with remarkable fidelity, offering a listening experience akin to that of a stationary high-fidelity system.

Comfort and design: the perfect balance

The GW100x not only excels in sound performance but also shines in ergonomics. The WS-type ear cushions provide optimal comfort, even during long listening sessions. The open-back design helps reduce listening fatigue by allowing natural airflow around the ears.

Attention to detail is evident in every aspect of the headphones. The adjustment mechanism, both robust and precise, allows each user to find their ideal position. The lightweight design of the GW100x, combined with balanced pressure distribution, makes it a pleasant companion for hours of uninterrupted listening.

Battery life and connectivity: the freedom to listen

With an impressive battery life of 46 hours at 50% volume, the GW100x redefines the standards of wireless listening. This exceptional performance frees users from the hassle of frequent recharging, allowing them to enjoy their music for several days without interruption.

Bluetooth 5.2 connectivity ensures stable, high-quality transmission up to 10 meters away. The GW100x supports aptX Adaptive, AAC, and SBC codecs, ensuring optimal compatibility with a wide range of devices. For purists or situations requiring a wired connection, the headphones can also be used with the included 3.5mm jack cable.

Versatility and uses

The GW100x excels in versatility. While designed to offer an audiophile listening experience at home, it adapts to various situations thanks to its hybrid wireless/wired design. Intuitive touch controls allow users to manage playback, volume, and calls directly from the headphones, providing appreciated convenience on the go.

The built-in microphone, with a sensitivity of 42 dB ± 3 dB, ensures clear voice quality for phone calls or video conferences. Compatibility with voice assistants adds an extra layer of functionality, enabling convenient hands-free control.
