But! A helmet is unfortunately not only decorative, it must also meet its primary purpose: the return.
On the phone, in urban environment and only listening, quality is satisfactory (in stereo). In talk mode, it switches to mono for listening and bandwidth decreases to allow the voice to pass. The quality becomes poor reception and microphone, very average, chopped conversations provides an important echo and many cuts in his voice.
On PC, defects found in phone mode only become larger, adding to it a ridiculous extent. Indeed, beyond two meters the signal degrades frankly. Difficult even to get away from his office.
A product to be reserved only to nomads, undemanding on sound quality, and much more attached to the product at its discretion and undeniable aesthetic.
