The JBL Live Buds 4 are the newest version in JBL's line of wireless earbuds, offering a range of features that can be controlled directly from their smart charging case. Unlike earlier models, users can now adjust sound settings, noise cancellation modes, and other functions without needing a companion app. These earbuds are part of JBL's Live series, which also includes the stemmed JBL Live Beam and the open-fit JBL Live Flex. The Live Buds 4 are said to include improvements over their predecessor, such as better noise cancellation, new "fidelity drivers" for clearer sound, and improved call quality. The charging case features a touchscreen with an updated user interface that allows users to tweak equalizer settings, select noise cancellation modes, change the appearance of the earbuds, and access tools like a flashlight and timer. While some users may prefer using the JBL Headphones app for more detailed customizations and larger screen access, the case provides a convenient way to make adjustments quickly. Additional features include a "smart-talk" option that uses voice recognition during calls and customizable touch controls on the earbuds themselves. In terms of call quality, the Live Buds 4 are equipped with six microphones and JBL's new Perfect Calls 2.0 technology, which uses artificial intelligence to improve voice clarity in noisy environments. However, some users reported that background noise and sibilance (a hissing sound) were still noticeable during calls. While the active noise cancellation has been improved, it still doesn't match the high standards set by competitors like Apple and Bose. Users noted that they could still hear ambient sounds such as conversations on public transport and office noises like typing and doors closing. The sound quality of the Live Buds 4 is generally praised, with strong bass, clean mid-range frequencies, and expressive highs that handle dynamic music well. They perform well across different music genres, offering detailed and rich audio. The use of the LDAC Bluetooth codec helps deliver more intricate mid-range details, enhancing the overall listening experience. However, the spatial audio feature, which simulates a surround sound effect, lacks the clarity and openness found in the standard sound tuning. The Live Buds 4 have a more discreet and secure design compared to the stemmed JBL Live Beam and Flex models, making them comfortable for long use. They are also IP55-rated, meaning they are resistant to splashes of water and dust. The battery life offers 8 hours of playback with noise cancellation enabled, and up to 40 hours with the charging case, which is competitive with other major brands. Released in May 2026 alongside the JBL Live Beam 4 and JBL Live Flex 4, the Live Buds 4 are priced at £179.99 or AU$269.95, the same as their predecessors. They are considered a good value compared to more expensive models like the Apple AirPods Pro 3 and Bose QuietComfort Ultra Earbuds Gen 2. The Huawei Freebuds Pro 5 is also recommended as a strong mid-range option at the same price, while the Technics EAH-AZ100 is considered the top choice for wireless earbuds across different budgets.
