JBL Live Flex 3

JBL Live Flex 3 Overview

Design and Build

The JBL Live Flex 3 features an open-stick true wireless design with a lightweight construction, with each earbud weighing around 4.5 grams. Unlike traditional in-ear earbuds with silicone tips, its open-stick design provides a more open and less intrusive fit. The earbuds come with a Smart Charging Case featuring a 1.45-inch touchscreen display, allowing users to manage music playback, adjust volume, control calls, and customize settings without opening the JBL Headphones app. The charging case weighs around 63.7 grams and also supports wireless charging.

Audio

The JBL Live Flex 3 is powered by 12mm dynamic drivers tuned to deliver JBL Signature Sound, with support for Hi-Res Audio Wireless. It has a frequency response range of 20Hz to 40kHz and an impedance of 13Ω. The earbuds also support JBL Spatial Sound for a more immersive listening experience.

For noise control, the Live Flex 3 features True Adaptive Noise Cancelling, which uses four noise-sensing microphones to automatically adjust noise cancellation according to your surroundings. It also supports Ambient Aware and TalkThru, allowing users to hear external sounds or have conversations without removing the earbuds. Through the JBL Headphones app, users can further customize their listening experience with Personi-Fi 3.0 and adjust the ambient sound settings.

Microphones and Controls

The JBL Live Flex 3 comes with six beamforming microphones designed to reduce wind and background noise during calls. It also features a voice equalizer and voice level optimizer, allowing users to customize how their voice sounds to others and how clearly they hear callers. The Smart Charging Case adds another layer of control through its touchscreen, letting users manage playback, answer or reject calls, adjust sound settings, view notifications, and personalize the case display. Users can also customize touch gestures through the JBL Headphones app.

Battery and Connectivity

Each JBL Live Flex 3 earbud packs a 50mAh battery, while the charging case houses a 690mAh battery. The earbuds offer up to 10 hours of playback with ANC turned off and up to 7 hours with ANC enabled. Combined with the charging case, they provide up to 50 hours of total playback with ANC off. A full recharge takes around two hours, while a 10-minute quick charge provides up to four additional hours of playback. The case also supports wireless charging.

For connectivity, the earbuds use Bluetooth 5.3 and support multipoint connection, allowing users to connect two devices simultaneously. They also support Google Finder and Audio Switch for added convenience. With an IP54 rating, the earbuds offer protection against dust and water splashes, making them suitable for everyday use.
