The new W1 chip from Apple is designed to facilitate a connection to Apple devices with just the tap of a on screen button on your iPhone. Simply turn on the headphones, make sure they’re near your phone, and follow the instructions that appear on your screen, assuming you have BlueTooth enabled. Once the headphones are connected, they’ll automatically show up on your other Apple devices signed into your iCloud account. Simply connect to them using the device you wish to use them with. The chip also helps achieve better BlueTooth range and battery life (up to 40 hours on the Solo 3’s,) so your headphones are ready to rock out wen you are. Plus, with the “Fast Fuel” feature, give them five minutes of charge time, and they’ll give you three hours of use. Hope that helps.
