I was looking for a Bluetooth headset for cycling and other sports activities and have easy times ordered me this here. For the headset speaks: -Practical clip for attachment (for example on the backpack) Speakers (handy for navigation) Jack (you can decide what you want to use headphones) Display (so I can see whether it is worthwhile to answer the call: D) To put it short: I am with battery life, talk and sound quality (both of the speaker, and the supplied headphones) and the practical SmartFeatures (as z.Bsp calls from the headset directly involved.) Very satisfied and thus convinced me this product !
