Review by Bernard

Package arrived well on time. Flat concerning the recharging of the batteries on the SENNHEISER support, the two red and green leds do not work correctly and I do not know if the charge is carried out or not. A battery with a red indicator light remaining on the other remaining lit on the green with an intensity which degrades ?? In use after about 45 minutes a sound signal when listening to the headphones sounds to inform me that the battery must be recharged while with the original batteries I have more than 15 hours of listening!

Paquet bien arrivé dans les délais. Bémol concernant la recharge des batteries sur le support SENNHEISER, les deux leds rouge et verte ne fonctionnent pas correctement et je ne sais pas si la charge s'effectue ou pas . Une batterie voyant rouge restant allumé l'autre restant allumé sur le vert avec une intensité qui se dégrade ?? A l'usage après 45 minutes environ un signal sonore dans l'écoute du casque retentit pour m'informer que la batterie dois être recharger alors qu'avec les batteries original j'ai plus de 15 h d'écoute !
