About this product

About this item Reduce Noise By Up to 98.5%: Liberty 4 NC noise cancelling earbuds have a high sensitivity in-ear sound sensor, an oversized driver, and an innovative noise isolation chamber that cancels up to 98.5% of noise for peaceful travel.
Noise Cancelling Adapts to Ears and Environments: Adaptive ANC 2.0 makes real-time calculations and adjusts to your ear canals and external environment for maximum quiet amongst the hustle and bustle.
Crisp Sound with 3× More Detail: 11mm custom-tuned drivers deliver consistently crisp and detailed sound. Experience Hi-Res wireless audio and LDAC technology that transfers 3× more data than regular Bluetooth—bringing wireless music to life.

Long-Lasting Battery Life: In normal mode, enjoy 10 hours of playback on a single charge or up to 50 hours with the case. With ANC on, get 8 hours between charges, extendable to 40 hours with the case.
Designed for Simple Connections: Liberty 4 NC enables quick, effortless Bluetooth pairing with Android devices, auto-play and pause on wear, and multi-point connection with Bluetooth 5.3.
IPX4 Water-Resistant: Don't let a sudden downpour or an accidental spill ruin your commute. Liberty 4 NC wireless noise cancelling earbuds come with IPX4 water-resistance to give you peace of mind during your travels.
