I had wanted a headset that you can also use outdoors eg beside a road. There is, however, much too quiet; even in an office environment, you can order his interlocutor probably does not always understand. In addition, it does not seem either to give the promised two-Micro noise reduction, or does not work well; Noise takes the microphone on as normal. I know other headsets, which itself can make calls from your car or while driving, cycling, without the interlocutor then something will notice by the sound around - that's not given safe here.
For the price okay, but not better than, say, the same expensive Plantronics competition despite the technical data supposedly better.
