Soundcore Liberty 4 — AirPod Energy. Way More Features.

The Soundcore Liberty 4 doesn’t just compete with premium earbuds — it outdoes them in almost every way that matters. Developed by Anker’s audio sub-brand, the Liberty 4 packs flagship-level features including a heart rate monitor, spatial audio with head tracking, LDAC support, and clean adaptive ANC — all in a design that would look at home next to any premium pair.

❤️ Built-In Heart Rate Monitor + Posture Detection

This is the feature that makes people do a double-take. The Liberty 4 earbuds have actual biometric sensors built in — a heart rate monitor and a posture detection system. Track your heart rate during workouts, or let the earbuds alert you when you’ve been sitting with poor posture for too long. It’s not a gimmick — it works, and it’s genuinely useful for fitness-conscious users.

🌐 3D Spatial Audio with Head Tracking

The Liberty 4 creates a wide, three-dimensional soundstage that adjusts dynamically as you turn your head. The result is an audio experience that feels less like listening through earbuds and more like being inside the music. For movie watching, anime, or gaming — this makes a noticeable difference.

🎵 Hi-Res Audio + LDAC Codec

With Hi-Res Audio certification and LDAC support, the Liberty 4 wirelessly streams music at up to 990kbps. Connect to a compatible Android device and experience lossless-quality audio without a single cable. Every instrument, every breath, every subtle reverb — rendered with remarkable detail.

🔇 Adaptive ANC with Wind Noise Mode

The Liberty 4’s ANC system uses barometric pressure sensors and a multi-mic array to intelligently adapt noise cancellation to your environment. The dedicated Wind Noise Reduction mode is a standout feature — particularly useful for outdoor use in Dhaka’s often breezy weather. Switch between modes easily via earbud controls or the Soundcore app.

🔋 9-Hour Battery + Wireless Charging

With up to 9 hours per charge and a total of 28 hours with the case, the Liberty 4 outlasts most competitors. The charging case supports both USB-C wired charging and wireless Qi charging — just set it on a wireless pad and let it top up overnight.

📱 Multi-Point Connection + Soundcore App

Multi-point connectivity lets you stay paired to two devices simultaneously — phone and laptop, for example. When a call comes in on your phone, audio switches automatically. The Soundcore app offers deep customization: EQ tuning, ANC controls, heart rate monitoring integration, and firmwaremanagement.

💧 IPX4 Water Resistance

Rated IPX4, the Liberty 4 handles sweat from workouts and light rain without issue. Not for swimming, but perfectly suited for active everyday use.
