The Jabra Stealth Bluetooth headset is processed perfectly. It is very well located in the ear, has sufficient support. Operation is simple and self-explanatory. Connection is made via NFC / Bluetooth, which should be no problem with any current smartphone. On my Samsung Galaxy anyway it was no problem. The manufacturer is the own statement "GET STARTED IN UNDER 5 MINUTES" justice. The reception & voice quality is very good. The use is not a problem both outdoors and in the car. The matching charger for the cigarette socket, in the jargon "smoker's package" is attached, as well as the matching Eargel phrases and earloop. With the great headset you are at all times, without having to pick up the phone. Unfortunately, the device is not a volume control available, so you still have to occasionally dig on the car seat while driving - which costs a star in the otherwise very good product. The interview time varies. Six hours are possible and standby is a maximum of ten days. The special feature is the smartphone voice control button to activate Siri / Google Now. I find this very handy when navigating to multiple destinations using Google Maps succession. Otherwise, the device has a noise-canceling dual microphone that has reduced background noise to follow, as well as high-definition audio quality and the transfer of music, podcasts or GPS announcements. The unit I am very satisfied, with the exception of times of missing volume control. Remedy can create the app Headset Droid. Under comments a useful page that explains everything exactly. So you get in a roundabout way still to the corresponding function.
