Edifier TWS330 NB True Wireless Earbuds Review:

• Active Noise Cancellation Technology: The Edifier TWS330 NB True Wireless Earbuds adopts hybrid ANC technology. The internal and external bidirectional microphones respectively pick up the internal and external ambient noise of the ear in order to generate a reverse sound wave to cancel out the noise. This creates a new depth noise reduction of -38dB, so the external world is quietened to create an immersive listening experience.
• Quick Charging: The charging case has a Type-C charge port, and the earphones support quick charging. 10min of charging will provide 60 minutes of listening.
• Ambient Sound Monitoring: No need to take off the earphones! Ambient noise monitoring technology allows you to hear external sounds, like traffic and flight broadcast information, whilst still listening to music.
• AI Phone Call Noise Cancellation: The Edifier TWS330 NB True Wireless Earbuds are equipped with deep neural network call noise cancellation, which accurately picks up sound waves using AI. With the help of an adaptive algorithm, the voice of the caller is separated from other voices in real-time, bringing a high-quality call experience.
• Low Latency Game Mode: While in Game Mode, the latency is as low as 80ms and there’s perfect synchronization between sound and images.
• Delicate Shape: Using the shape of an egg for inspiration, the headphones have a graceful curve to create a smooth touch. They are lightweight, portable, and comfortable to wear.
• AAC Decoding: AAC HD audio decoding provides higher quality audio transmission and excellent sound quality, beautifully restoring every detail of sound.
• 20h Running Time: The battery life for the earphones is about 5 hours. The overall battery life can reach 20 hours when combined with the charging case, providing hours of excellent, high-quality listening.
