Listen to music whilst you work out with the reversible Plantronics Fit Armband. The blue side is for when you want to use the armband whilst running and the black side is for storing your BackBeat Plantronics headset. When using the blue side there is also a high vis reflector which is great for running at night. The armband will fit phones with a maximum height of 14cm and width of 7.4cm; this means it will work with phones such as the iPhone 6 and Galaxy S5.
