Thank you for sharing your thoughts on the Galaxy Buds2 Pro, Nelly. The Buds2 Pro provide studio-quality sound that is not just for professionals. They offer an immersive listening experience that begins with full 24-bit audio, ensuring clear and rich sound. With Intelligent Active Noise Cancellation, you can hear what matters most because it effectively reduces even the loudest sounds. Whether you are enjoying music or taking calls, the Galaxy Buds2 Pro help you focus on what is important while minimizing distractions. We appreciate your feedback regarding the ringing noise in ambient or noise-cancelling mode. When using features like Active Noise Cancelling (ANC) or Ambient Sound, the sub microphone may pick up sounds from the environment. This can create a beeping or howling noise when wearing, removing, or adjusting the earbuds, especially if the sub microphone is accidentally covered. To enhance your experience, try to ensure that the sub microphone remains unobstructed while using the earbuds. Products sold by Samsung are warranted against manufacturing defects in material and workmanship for the limited 12-month warranty period specified for each product.
