I bought this unit (tested after 7 or 8) it is really good 1) must, however, change the headphones (sony 26) 2) To use the charger you need to buy a universal travel adapter 10 3) Little is properly tailor the noise acting on the balance and tone (setting potentiometer in the battery box) 4) I advise to use it with one headset on the lower ear and do not send all the power (adjustment knob and balance + tone that modulates) (hint name was with the balance potentiometer spend more on loreillette unused power which had the effect to reduce noise). (I spent a few hours testing to have a very good sound quality) I insist on setting it is paramount. 5) A good settings eliminates much of the noise 6) My wife found a listening comfort by 40% and rose to 95% (my estimate) 7) The microphone is far earphones no whistle (feedback) 8) I can only recommend this product for a small fee which allows to find maximum listening comfort 9) I tried t ... A prosthesis very very expensive, it do better war and are very difficult to adjust 10) This product can not be regarded as a hearing aid, it has yet all the benefits and many reg ', I do not think it presents a danger 11) Last but manual is very brief and does not indicate all settings can I not find useful to external microphone with three meters of cable. the charger connector to the fragile air 13) batteries hold 60 hours minimum continuous power in position 1 14) I did not test the magnetic loop (cursor necklace non fourniposition T) but there is no reason why it does not work 15) Many accessories including a strap (which allows to take the neck) and a carry bag Yves
