Background and Identification
Bose Quietcomfort 25 headphones are a noise-canceling, over-ear headphone device. These headphones utilize noise cancelling technology to limit the amount of outside noise interference and allow the user to focus on the music or sounds they want to hear. The QuietComfort 25 headphones include an inline microphone for accepting and using the call feature on mobile devices. These headphones have been designed for travel in mind, making sure to cut down on unnecessary weight, while also including comfortable materials for long time usage. Note that there are two models of this device: one for Apple devices and one for Android devices. Bose QuietComfort 25 headphones are small, light, fashionable, and foldable. Available colors are gray and black, or tan and white look.
The QuietComfort 25 differs from its predecessor, the QuietComfort 15, with the introduction of passive listening, which provides users with the option of listening to music without batteries; though, with passive listening, the noise-canceling feature does not function.
As it was released in 2014, the QuietComfort 25 has been followed by later models; it was replaced in March 2016 by QuietComfort 35.
