Bose 4.2 (Series I)

Brand: Bose

The Bose 4.2 (Series I) is a set of noise-cancelling headphones that was released by Bose Corporation in 2004. The headphones use a technology called Passive Noise Reduction, as well as Active Noise Canceling to block out external sound. The "4.2" in the name refers to the fact that these headphones come with a detachable microphone and remote that can be used with Apple iPods and other devices that support the standard. The Series I refers to the first generation of these headphones, with subsequent generations being the Series II and QuietComfort 35 II (QC35 II). Despite being almost two decades old, the Bose 4.2 (Series I) is still considered a popular and effective choice for those looking for noise-cancelling headphones.
