Rather accustomed to mp3 players "entry level", what has not been my pleasure to rediscover my favorite pieces with a real sound quality on a "pocket" drive. No complaints for exclusive audio use except the restitution of the original helmet that is not up to the possibilities of the device. So I "invested" in a better helmet 2 comments must be made: - You have to play with the degree of insertion of the jack (plug) to match the helmet of contact points with those of the apparatus; I started to insert the plug to the stop and the sound was completely "choked". I specify that the jack from my headphones has four contact points (3 streaks on the sheet) as it includes a microphone. - The precise instructions that "the player does not work properly with 4-way earphones." This is indicated at the end of instructions in the "Troubleshooting". This should be more forward, as a warning appear in the specifications, for example; That said, I'm not sure that there are 4 ways headphones (3-way high-end in 300-400), I wonder if they do not speak rather of contact points ...
