[ads right[1]]Functionality:

Pairing is done like usual, by holding the on/off button while the unit is switched off, until the LED indicator starts flashing in blue. The device will be thus detected and connected; the code to be entered is “0000.”

During our testing, it was possible to use all the control buttons; however, their functioning depends on the paired device as well.
Besides the standard functions, there is also the opportunity to lock/unlock the keys by quickly pressing/releasing the on/off button.


Performance:

According to the manufacturer’s specifications, the device should endure up to 8 hours in talk mode or 150 hours in standby; respectively, the operating range should measure up to 10 meters. Having been subjected to testing in real conditions, the device performed quite close to the official specification – 7 hours and 20 minutes non-stop conversation at maximum volume and no change in signal quality at even 28 meters (91.8 feet). Nonetheless, its battery time is fairly lower than that of competitive models such as Nokia BH-601 or Motorola HT820.

Due to the specific design of the headphones, audibility, while having a conversation outdoors will not be disturbed by any noise – it is suppressed by the ear pads. Sound volume is rather high, so you will hardly find yourself at a location with a noise so strong as to find the words of the collocutor unintelligible. Voices sound sharply, which is unpleasant and outright irksome, especially if sound volume is at the maximum level. This makes voices sound rather unreal for the ear, but all the same intelligible.

Though the sound is strong at the other end of the line, you should bear in mind that turning the head will increase the distance to the microphone thus causing your voice to sound more weakly at the other end. To avoid this signal disturbance and ensure a good volume and clear sound for the collocutor’s ear, it is desirable that you place the unit as close to your mouth as possible.

As far as the headphones' main function is concerned, we have been disappointed by their poor performance – when listening to music, sound quality is far lower than what we have anticipated. With a view to the fact that the headphones are noise-proof, we expected their quality to be similar to that of cable ones, supplied with mobile phones (such as the Walkman units of Sony Ericsson, for example), but their performance turned to be much worse. Not a single segment of frequency is fully reproduced, rendering music sound as if played on a low-grade telephone speaker – entirely flat and emotionless. Regrettably, even replacing the original headphones by high-quality ones (thanks to the 3.5 mm socket) did not result in reproducing the type of sound we were looking for, though it did improve the quality a great deal, indeed. Clearly, it is the quality of the chip that is to blame.
