The JBL Live Buds 4 wireless headphones feature a closed, in-ear design for everyday listening. They use modern Bluetooth 6.0 wireless technology for signal transmission. The True Adaptive Noise Cancelling 2.0 feature effectively isolates ambient sounds. The headphones offer up to 10 hours of battery life on a single charge. The case with its own battery provides an additional 30 hours of use. This extends the total operating time to 40 hours without needing to find a power outlet.
The 10mm dynamic driver provides a balanced sound with clear details and deep bass. JBL Spatial Sound technology converts a standard stereo signal into a three-dimensional format. Users can customise the sound curve using Personi-Fi 3.0 based on their own hearing test. The headphones support the A2DP 1.4, AVRCP 1.6.3, and HFP 1.8 wireless profiles.
The True Adaptive Noise Cancelling 2.0 system continuously analyses the external environment and dampens distracting sounds. In contrast, the Smart Ambient feature lets in important ambient sounds for safe movement outdoors. Smart Talk technology automatically pauses playback when you start a conversation, with no manual control needed. You can adjust the transparency intensity in the companion app.
The headphones provide up to 10 hours of music playback with BT on and ANC off. With BT and active ANC on, the battery life drops to up to 8 hours, or up to 7 hours with True Adaptive ANC enabled. The charging case with its 590mAh lithium-ion polymer battery holds power for up to another 30 hours of use. In total, you get up to 40 hours of listening time. A quick 10-minute charge via USB-C provides enough power for 4 hours of use, while a full charge from empty takes about 2 hours. The case also supports convenient wireless Qi charging.
The Perfect Calls 2.0 system, which consists of a total of 6 integrated microphones with beamforming technology, ensures your voice is transmitted clearly. This system uses advanced artificial intelligence algorithms to effectively filter out ambient noise. Your voice remains perfectly intelligible and natural, even when making calls in a noisy urban environment. For calls, the battery lasts up to 5.5 hours with ANC off, or up to 4.5 hours with ANC on. In the JBL Headphones mobile app, you can also easily adjust call effects and levels to suit the current situation.
The Smart Charging Case features a touchscreen for quick volume changes or track switching. Support for Google Finder and Audio Switch makes it easy to locate and switch between paired devices. Bluetooth 6.0 wireless technology provides a stable connection with low power consumption thanks to LE Audio. The JBL Headphones app is used for detailed configuration of all features.
