QuietComfort 25 Acoustic Noise Cancelling

About the QuietComfort 25 Acoustic Noise Cancelling

The Bose QuietComfort 25 headphones feature advanced active noise cancellation technology developed from over 30 years of research, effectively reducing ambient noise especially at low frequencies. They use microphones inside and outside the earcups to sense unwanted sounds and a proprietary digital chip to generate precise noise cancellation signals. The headphones reproduce music with improved clarity and accuracy through a finely tuned Active EQ and TriPort® technology for deep, detailed bass. They are lightweight and comfortable, with protein leather ear cushions and a headband padded with engineered fabric. Powered by a single AAA battery, they offer up to 35 hours of noise-cancelling use, and can still function without the battery but without noise cancellation. The headphones include a 56" cable with inline remote and microphone, an airline adapter, and a carrying case. The earcups rotate for a better fit and fold for portability. They are wired headphones designed primarily for Apple devices but compatible with others via the 3.5mm jack. The sound signature is balanced with good midrange and treble detail, and the noise cancellation is highly effective for commuting and travel environments. However, they do not have Bluetooth or rechargeable batteries, relying instead on replaceable AAA batteries.
