Let's hope that despite its high price (nearly 300 euros on the Sennheiser website), Ambeo Smart Headset intras are likely to end on many upcoming shopping lists. And owners of iPhone are particularly spoiled since this binaural headset is for the moment exclusive to iOS (an Android version will come later, without date specification, however). The Ambeo Smart Headset is therefore "the first set of portable binaural headset-microphones", which not only allows you to listen to 3D sound recorded in Binaural (which can be done by any stereo headphones of good quality) but also to record in Binaural (360-degree 3D sound) ambient sounds around the user, while filming with his iPhone of course! The holiday movies will have a sacred sound … The 3D effect is quite amazing (we really feel like being directly in the sound scene – see video below) and Sennheiser promises a high quality sound to the "simple" listening. The Transparent Hearing feature also allows you to hear outside noises during music playback or video recording, "a valuable security asset"; a three-position selector offers the choice between a truly "transparent" listening (as a very open intra in short …) until closed listening mode, in isolation with the music. serves for phone calls or voice control (Siri). And as these intras are paid in addition to the luxury of being pretty pretty once worn … Ambeo Smart Headset intras are available at a price of 299 € on the manufacturer's website.
