Jaybird X3 are new wireless sports headphones bringing larger sound, thanks to an enhanced 6mm driver, as well as smaller size, making it the first in the X-Series to be helmet compatible. The redesigned enhanced-comfort ear fins and selection of ear tips provide a universal secure sport fit during the toughest of workouts. Bluetooth 4.1 connectivity, allows for pairing of two sets of X3 headphones to one device or a single X3s to two devices simultaneously. The redesigned eight-hour battery gives even more music on a single charge, and the new in-line remote makes it even easier to control music and calls. MySound App, allows for customization of sound settings to personal preferences. Custom sound profile is then saved on the X3 headphones, so no matter what music device they’re paired with or which music service used, they’ll always be tailored to each person.
