Each earbud fits snugly into your ear and feels light enough for long listening sessions. It supports Bluetooth 5.3 for a quick and stable connection. The impedance is 10 Ohms, which balances good sound output with energy efficiency.

Features

These earbuds come with advanced Adaptive ANC 2.0. This feature automatically adjusts noise cancellation based on your environment and ear shape. The 11mm custom-tuned drivers deliver clean, rich, and detailed sound. You get Hi-Res Audio Wireless support through LDAC, which allows you to enjoy more sound detail than regular Bluetooth.

The HearID 2.0 technology helps create a sound profile based on your hearing pattern. The Soundcore app lets you pick from 22 EQ presets or adjust manually. The earbuds are IPX4 water-resistant, so rain or sweat won’t be a problem. They also support multi-point connectivity, meaning you can pair them with two devices at the same time.

Battery life is impressive 10 hours per charge and up to 50 hours with the case. With active noise cancellation (ANC) on, it still offers 8 hours of playtime. The 6-mic AI calling system ensures clear phone calls by cutting down background noise.

It comes in Glossy Black and has an impedance of 8 Ohms, offering a slightly louder and more dynamic sound. It’s built for those who want a deeper listening experience with strong noise reduction and studio-grade sound clarity.

Features

Liberty 4 Pro uses 7 sensors, including 6 sound sensors and a barometric pressure sensor, to detect and block noise from every direction. The Real-Time Adaptive Noise Reduction system adjusts every 0.3 seconds to keep sound consistent. This means you can move from a busy street to a quiet café, and the earbuds will adapt instantly.

For audio performance, it features ACAA 3.0 dual drivers — a 10.5mm bass driver and a titanium-coated tweeter. This setup gives richer lows, crisp mids, and sparkling highs. The digital crossover helps separate frequencies accurately, giving a balanced sound similar to studio headphones.

The touch bar control on the case is a new addition. You can slide or tap to adjust ANC levels without opening your phone. Battery life is strong, with 10 hours of playtime per charge and up to 40 hours with the case. A 5-minute quick charge gives 4 hours of playback — ideal for busy users.

For calls, Liberty 4 Pro uses 6 microphones with AI noise reduction and a wind filter system, giving clear voice quality even in windy or noisy areas.

• 7-sensor noise cancellation is very powerful.

• Dual drivers deliver rich, detailed, and dynamic sound.

• Touch bar on case makes control easy.

It gives a studio-like sound profile and quick control features, making it a perfect choice for travelers and audiophiles. The higher price is worth it for users who care deeply about premium sound performance.
