The iOS‎-compatible‎,‎ black‎-colored version of the Bose QuietComfort 25 Acoustic Noise Cancelling Headphones build upon the company's reputation for active noise cancellation technology with a re‎-engineered sound signature‎,‎ a more lightweight ergonomic design with adjustable headband‎,‎ and circum‎-aural rotating earcups with suede‎-like padding that fold in for better portability using the included carry case‎.‎

The sound of the headphones was designed by a team of both engineers and musicians to have deep bass and clear treble using Bose's Active EQ and TriPort technologies‎.‎ Your ability to enjoy these features is enhanced through the active noise filtering circuit‎.‎ Powered by a single AAA battery‎,‎ the headphones utilize external microphones to capture ambient noise such as street sounds or the cabin noise in an airplane‎,‎ which is then processed and mixed back into the audio signal out of phase to help reduce the ambient sound within the headphone mix‎.‎

The headphones come with a 3‎-button‎,‎ in‎-line and iOS‎-compatible remote control cable for answering calls‎,‎ adjusting the volume‎,‎ and navigating tracks on select iOS mobile devices as well as many other popular smartphones‎.‎ Please see the manufacturer's website for device compatibility‎.‎
