ERGONOMICS 
A slew of features
The Plantronics BackBeat Pro is a closed circum-aural dynamic headphones resourceful. It will take more than an hour to tour of its features. Let's start by look rather impressive: his ear cups are coated with a solid plastic shell brushed finish and steel grilles. Swivel flat and in the direction of height, they offer some comfort on the head and an easier port choker helmet. If one wants to push the vice, we would have appreciated a recent downturn to the hoop for easy transport. From circum-aural design, it has thick soft leatherette ear pads, airy and very comfortable - no problem alongside large heads and big ears. Its flexible headband and serrated steel, easily adjustable thanks to its bearings, is covered with a thick foam leatherette. Discreet, elegant and with a good finish, the BackBeat Pro suit all age groups and all types use, except of course the sport. Its excellent and very comfortable he lavishes allow long hours of listening, despite a relatively high weight of 340 g. The BackBeat Pro is a wireless headset with an NFC chip that communicates with Bluetooth 4.0 EDR and A2DP for a very large range (about 100 m). For non-compatible NFC terminals, the pairing is done easily (5 s pressure on the Pickup button), the headset can store two terminals. It is also equipped with microphones for receiving calls wirelessly. Let us not forget either the reduction of active noise, the performances will be analyzed later in this article. Another strong point is its autonomy impressive is 24 hours with active noise reduction, which is a good week of intensive use. Allow two to three hours to fully charge the battery using the supplied USB cable. Plantronics has incorporated DeepSleep technology, a hibernation mode for extending the battery life up to six months - a useful feature to avoid the sad experience of a discharged battery after an extinction forget the camera. For aficionados of the wired experience, a cable / remote with a microphone and microwave 3.5mm angled connector is provided. After use, the BackBeat Pro fits in the spacious soft carry case which resumes black and indigo code of the product and its accessories. from either side of the helmet, there are numerous discrete physical controls, which have the merit of being accurate, responsive and intuitive. To our left, a large button to play / pause as well as activation of the NFC. It is encircled with a stop wheel for navigation between the tracks (next / previous song).At the rear, there is the activation of the noise reduction switch, micro-USB connector for charging and entry into mini-jack 3.5 mm. To our right, the main center button allows management calls (answer / end / redial the last call) while coasting knob controls the volume. Putting control on / off is at the rear, where lies an attenuator (or dimmer ) music activates the same time the headset microphone to hear the conversations around without even having to lift a headset. Under mastoc air, this helmet hides a subtle, with bright and voice directions for most functions. LEDs are integrated in each atrium and indicate the ignition, activation of the reduction of noise and the level of battery in use or refill. Voice alerts, available in 14 languages, always remain audible and clear, a jingle sound is played when lighting and a range of notes accompanying the rise in volume. In addition, the multilingual voices indicates power off ( " power off "), battery level (" battery high "," battery low "), the connected device, the maximum and minimum threshold reached and finally the activation / deactivation of the noise reduction. The California manufacturer goes even further: when the left ear is raised or the headset is removed, the music decreases fade out . Similarly, when the helmet back on our ears, the music starts again at the same place in fade in (low volume) to avoid unpleasant surprises. Best of all, after a long period of inactivity without having turned off when the BackBeat Pro is placed again on the ears, the voice alert reminds you the level of the battery and the device number logged.
