Enjoy super active noise cancellation with the Hear+Hi Serena Earbuds wireless ANC buds. Boasting up to 45 dB of noise cancellation, they ensure you hear crystal-clear audio no matter your surroundings. This helps keep your ears safe from incurring long-term damage—which can happen when you listen to audio at high volumes. Designed by hearing aid experts, these earbuds suppress noise and echoes so you clearly hear speech. Moreover, with at least 7 hours of battery life, these advanced earbuds also use Bluetooth 5.0 dual-mode connectivity. Affordable and durable in their design, Serena has a comfortable and small fit in your ears. Fully immerse yourself in whatever you listen to and enjoy never setting the volume higher than 75%. Made with 2 microphones, they detect noise close to your eardrum and recognize which sounds to let through.
