This image displays the Boult Klarity 3 earbuds in their silver color, resting within their sleek charging case. The earbuds feature a metallic finish and a distinctive fluted design on the stems. The charging case is compact and designed for portability, providing power to the earbuds on the go.
Advanced Audio Technologies

The Boult Klarity 3 incorporates several advanced technologies for an enhanced listening experience. This includes 50dB Hybrid Active Noise Cancellation (ANC) for significant noise reduction, Hex Mic Environmental Noise Cancellation (ENC) for clear calls, and Spatial Audio for immersive sound. The earbuds also support Dual Device Pairing, offer up to 50 hours of total playtime, and utilize Bluetooth 5.4 for stable connectivity. Control and customization are available via the Boult Amp App, and a low latency of 45ms is ideal for gaming.
Hybrid Active Noise Cancellation (ANC)

The Klarity 3 features a powerful 50dB Hybrid ANC system. Unlike standard ANC, this advanced system uses a 6-microphone setup, including feedback and feedforward mics, to effectively block a wider range of frequencies and eliminate ambient noise, providing a more profound quiet listening environment.
Spatial Audio Experience

Experience a new dimension of sound with Spatial Audio. This feature creates a 360-degree soundstage, making audio feel more dynamic and lifelike. It enhances your music and movies by providing a sense of direction for instruments and sounds, offering a truly immersive listening experience.
Boult AMP App Connectivity

Unlock the full potential of your Klarity 3 earbuds with the Boult AMP App. The dedicated app allows you to customize EQ modes, switch between listening modes (e.g., Gaming or Music), rename your earbuds, and assign custom touch controls. It also offers widget support for your home screen and an innovative earbud cleaning feature.
Extended Playtime and Fast Charging

The Boult Klarity 3 offers an impressive total playtime of up to 50 hours with the charging case. It supports Type-C Fast Charging, providing 120 minutes of playtime from just a 10-minute charge, ensuring your earbuds are ready for extended use.
Hex Mic Environmental Noise Cancellation (ENC)

For crystal-clear calls, the Klarity 3 features Hex Mic Environmental Noise Cancellation (ENC). This 6-microphone array effectively filters out background noise, including wind, ensuring your voice is heard clearly by the listener, even in noisy environments.
Bluetooth 5.4 and Dual Device Connectivity

Equipped with Bluetooth 5.4, the Klarity 3 provides a stable and fast wireless connection. The Dual Device Pairing feature allows you to connect to two devices simultaneously, enabling seamless switching between your phone and laptop without needing to disconnect and reconnect.
13mm Bass Drivers and Low Latency Gaming Mode

The Klarity 3 delivers powerful audio with its large 13mm BoomX™ Bass Drivers, providing deep, punchy bass and a rich sound profile. For gamers, the dedicated Combat™ Gaming Mode ensures ultra-low latency of 45ms, synchronizing audio and visuals for an immersive gaming experience.
IPX5 Water Resistance and Intuitive Touch Controls

The earbuds are rated IPX5 water resistant, making them splash, sweat, and rain proof, suitable for various activities. They feature intuitive Touch Controls for easy management of music playback, calls, volume adjustment, and mode switching. Voice assistant support (Google Assistant, Siri, Amazon Alexa) is also integrated.
