1. UA FLASH by JBL and Under Armour
Under Armour has teamed up with sound experts JBL to create its first-ever truly wireless headphones, UA True Wireless FLASH. Designed with running in mind, Under Armour has set out to solve two common running problems—tangled cords and water damage from sweaty training sessions. The result is earbuds that are fully-cord free so you can concentrate on your run and with UA Storm Proof waterproof technology. JBL has added in its JBL Charged Sound to give a clear high-quality sound, while the AmbientAware mode means runners can still listen to their music while turning up background noises so they can stay aware of their outdoor surroundings.
