Sennheiser Rs110 926 Mhz Wireless Rf Headphones

Hi everyone,
I got the device today only try to assemble it and had problems .My trasmitting station always reset (using with creative muVo mp3 player)after 1~2 seconds and it get started only when I put audio source jack into tx antenna kind of stuff.
It may be my usage flaw, but its giving hard time to me to play it...
And it make me sad :-( for purchase.
