Sealed headphones are a popular accessory for music lovers who prefer not to be disturbed by outside noise. However, there are several synonyms for sealed headphones, including closed-back headphones, over-ear headphones, and noise-isolating headphones. Closed-back headphones have a solid backing that blocks out external sound. Over-ear headphones, as the name suggests, provide complete coverage over the ears and offer excellent noise cancellation. Noise-isolating headphones are designed to reduce external noise and keep your audio experience free from disturbances. Whatever your preference may be, there are plenty of choices for sealed headphones that can enhance your listening experience.
