Sorry, there was a problem. Please try again later.The Soundcore Sleep A20 earbuds are not equipped with active noise cancellation (ANC), relying instead on passive noise reduction. This reduction can be enhanced by selecting the right size ear tips and wings to create a snug fit, ensuring a good seal and minimizing external noise. Additionally, the earbuds feature a Smart Volume Control that can adjust the volume of sleep sounds according to the external noise levels after detecting you have fallen asleep. While these features may help reduce and mask TV noise, the effectiveness will depend on factors such as the volume of the TV and your personal sensitivity to noise. If the TV is particularly loud, this may not entirely block it out. Proper fit and adjustments could improve your experience for a more restful sleep.
