The W1 chip is Apple’s new technology for making Bluetooth a lot more user-friendly. The W1 chip enables painless pairing with an iPhone running iOS 10 or later. Once paired, the configuration is then synced automatically to all your other connected Apple devices using iCloud.
W1 headphones also tout significantly longer battery life and wireless range, built on Class 1 Bluetooth standards. The Beats Solo3 can play music for more than 40 hours without needing a charge, at distances up to 150 feet.
Although the W1 chip headphones are optimized for compatibility with Apple devices, they also work with any device that sports Bluetooth compatibility.
