I'm a fan of Logitech products for a long time and it's not the helmet that will make me change my mind. The dimensions are impressive, but once in place the helmet on his head knows how to forget, the presence of foam from earphones and headband (not plastic) contributes greatly to the comfort, even over long periods (2 / 3 hours, it is not to live with). The setting is simple, the microphone folds and unfolds easily, large size headphones turn on themselves to ensure optimal implementation and a good wrap your ears. They greatly attenuate background noise. Once the music started, the outside world is (almost) forget even gently on the volume. Only violent sounds really be heard. Sound level is more than adequate, from low to high all notes are collected with good readability even on pieces "traps". The cable is 3.18 m, needless to say that this is more than enough for normal use, including watching TV, if your living room is not too big. It has a Velcro loop allowing you to attach the cable when folded and avoid having to wrap or see tangling. The only flaw of the wire (in the long term) is the outer protective braiding that resembles those of some mouse son who sometimes do not age well, and create "loops" at the whim of movement and winding / successive sequences ... to see ... A small control box is located on the cable (about 70 cm of the helmet to knock you off fairly well in the hand), which allows you to adjust the volume and mute the microphone. The case is provided with a small "clip" for attaching to clothing or at a belt (not too thick belt) In short: A flawless.
