Background and Identification
Bose headphones are manufactured by the American company, Bose Corporation. Bose produces all sorts of sound equipment like automotive stereos and Bluetooth speakers, and likewise their headphone offerings range from aviation headsets to "Open-Ear" audio sunglasses. They are perhaps best known for their QuietComfort series, which has evolved over the years from wired on-ear headphones to wireless over-ear and in-ear sets with bluetooth and noise-cancelling technologies.
Most Bose headsets will display the Bose logo printed on the speaker or headband. To identify the model of your Bose headphones, check the product name, which should be printed along the outside of the band. It should look something like this: QuietComfort 35 II. Bose headphones also have an ‘L’ and ‘R’ label corresponding to their left and right sides.
If you're looking to do more than a earpad or headband replacement, you'll likely require a soldering iron and some skill. Bose headphones don't typically feature modular cable connectors, but are still repairable given the proper effort and patience.
