The JBL Live Buds 4 in elegant Champagne are true wireless earbuds designed for a versatile listening experience, featuring 10 mm dynamic drivers that deliver JBL Signature Sound. These earbuds support Hi-Res Audio Wireless and Spatial Sound, allowing you to enjoy a wide frequency response from 20 Hz to 40 kHz. To help you stay focused in noisy environments, they utilize True Adaptive Noise Cancelling 2.0, while six beamforming microphones paired with an AI-trained algorithm ensure your voice remains clear during calls. A standout feature of this Champagne model is the smart charging case, which includes an intuitive built-in display that lets you adjust volume, switch tracks, and manage noise settings without needing to reach for your phone. The earbuds are built to be durable with an IP55 rating for water and dust resistance, making them suitable for various daily activities. You can customize your experience further through the JBL Headphones app, using Personi-Fi 3.0 to tailor the sound to your hearing or adjusting gesture controls. Battery performance is robust, offering up to 10 hours of playback in the earbuds alone when noise cancelling is off, extending to a total of 40 hours with the case. If you are in a hurry, a quick 10-minute USB Type-C charge provides 4 hours of listening time, though the case also supports Qi wireless charging for convenience. Connectivity is handled by Bluetooth 6.0, which enables modern features like LE Audio, Auracast, and multi-point connection for switching between devices seamlessly.
