JBL Live Flex4 Champagne

The JBL Live Flex 4 wireless earphones, with their semi-open bud design, deliver a stable connection using modern Bluetooth 6.0 technology. The earphones use adaptive noise cancelling to effectively suppress ambient noise while you listen. The integrated battery provides a total battery life of up to 50 hours when combined with the charging case. The earphones themselves can play for 10 hours without active noise cancelling, and they can be conveniently charged via USB-C or wirelessly. Their durable construction with an IP54 rating protects the device from dust and splashing water.

Sound and Tuning

The 12mm drivers deliver a balanced sound with an emphasis on crisp details and deep bass. Wireless technology transmits audio nuances across a wide frequency range of 20Hz to 40kHz. The spatial sound feature creates a three-dimensional listening space for a more natural perception of recordings. In addition, the Personi-Fi 3.0 tool helps you customise the sound curve to your personal hearing profile.

Noise Cancelling and Transparency Mode

True Adaptive Noise Cancelling 2.0 technology actively suppresses ambient noise based on a real-time analysis of your environment. Meanwhile, Ambient Aware mode makes it easier to perceive sounds from your surroundings when you need to stay alert. The system automatically reacts to your voice and pauses playback via the Smart Talk feature. You can easily adjust the level of both transparency and noise cancelling in the mobile app.

Battery Life and Charging

The earphones offer up to 10 hours of continuous use with noise cancelling turned off. The charging case holds power for an additional 40 hours of use, giving you a total of 50 hours of listening time. Just a 10-minute quick charge provides enough power for 4 hours of playback. A standard USB-C connector or Qi-certified wireless pads can be used for recharging.

Calls and Microphone

A total of six microphones with beamforming technology ensure clarity during phone calls. The integrated AI-trained algorithm effectively filters out wind and street noise. The Voice Aware feature helps you control the volume of your own voice that you hear in the earphones during a call. The microphone parameters can be fine-tuned to suit your current surroundings.

Controls, App and Pairing

The Smart Charging Case features a touch screen for direct parameter adjustments without needing to take out your phone. On the screen, you can change the volume, switch tracks, or activate noise cancelling modes. The mobile app offers complete management of all functions, including equaliser adjustments. The earphones support Google Finder for quick pairing and seamless switching between multiple paired audio sources.
