Liberty 4 white earbuds

Start by identifying your main priority: stronger noise isolation, a longer battery life, or customizing your sound. In this range, you’ll find models that combine these features. The Liberty 4 NC offers noise reduction up to 98.5% with Adaptive ANC 2.0, which adjusts to your ear and your environment in real time. It also includes 11 mm drivers, high-quality sound with LDAC technology, and customizable audio via Hear ID 2.0. Battery lasts up to 50 hours using the case in power-saving mode, and up to 10 hours when using the earbuds alone. Connectivity is available through Bluetooth 5.3 with multi-point support, IPX4 water resistance, and 6 microphones for clear calls. There’s also a Liberty 4 Pro option with an 18-month warranty for those looking for a more premium choice.

Adaptive ANC 2.0 is one of the most advanced approaches to noise reduction because it automatically adjusts the level of isolation based on your ear movement and the type of surrounding noise. In practice, you’ll notice less noise on commutes and in crowds, while important sounds remain clear when you need to talk. The isolation is handled in real time with a high level of noise reduction, so you can listen to your favorite audio clearly without feeling worn out. This feature is supported by advanced audio tech such as LDAC and customizable sound through Hear ID 2.0.

This series is great for people who commute every day and care about call quality, thanks to six microphones and an AI algorithm that improves calls in the presence of background noise. You also get high-resolution audio with dual 11 mm drivers and the option for customized sound through Hear ID 2.0 to match your preferences. Plus, you get long battery life—up to 50 hours with the case and 10 hours on the earbuds—along with fast switching via Bluetooth 5.3 and multi-point integration so you can connect to multiple devices at the same time.

Care for your Liberty earbuds by gently cleaning with a dry wipe and avoiding water unless the earbuds are water resistant. Keep the case charged regularly. They’re compatible with phones and tablets via Bluetooth 5.3, with multi-point support for connecting more than one device at the same time. For setup, there’s a special note in an instructional video for Samsung Galaxy S23-series; we recommend watching the video to pair correctly with that specific phone model, making the connection faster and easier.

Liberty 4 NC focuses on a strong balance of noise isolation and sound quality, with long battery life and multiple integrations. Liberty 4 Pro is a stronger choice for a more premium listening experience, offering superior isolation and more comfort, with a relatively longer warranty of up to 18 months. Both options deliver high-quality sound and customization via Hear ID 2.0, but the higher tier with the longer warranty may suit those who prioritize sound quality and long-term comfort.

Yes. Using the clear-call features with 6 microphones and an AI algorithm improves audio clarity and reduces surrounding noise. With Adaptive ANC 2.0, you can achieve a noticeable reduction in background noise during calls, making your voice clearer to the listener even in busy environments. Multi-point connectivity also keeps calls going smoothly even when switching between devices, so your experience stays seamless when moving between your phone and tablet.
