FM Antenna - the earphone cord?

Hey All - just got a Clip Port Plus. I believe the earbud cord acts as the FM antenna. I plan to use this in the gym while watching the TV with FM transmission. Can someone verify this? This may indicate I need an antenna plugged into the head phone jack. I can hear via B/T strong stations, but only get a few w/o a headset plugged in.

Sorry for the new-bee question but wanted to ask as I play with the product.

Thanks

Scott

correct the wired headphones act as the antenna for the FM radio. 

Great to hear that you were able to get any FM reception via BT–I’ve never managed that with other players.  Will have to try some more.
