Excellent value for money. For TV, and elderly or ill-hearing people. Used with or without hearing aids. Not really the HI-FI. But the next "open" is ideal helmet to avoid being cut off from the world while watching TV (ringtones, téléhones, comments, etc ..) Good quality of radio transmissions (usual Sennheiser). Too bad the receiving channel is adjusted by a wheel and automatically. Lightweight and comfortable to wear without pain for pavilions ears for several hours. I quoted what I think is the best use of this helmet because I gave my mother 83, and paired with hearing trouble. The frequency curve is very linear but perhaps slightly pousséée in the midrange, making the very understandable word, which is good for emmission TV and movies. Recommend urgently for this purpose.
Good all the same for everybody, and at that price, nothing to say, but with the advantages and disadvantages of the helmet "open".
