I bought 2 bluetooth items for my Sansa Clip: 1. GOgroove BlueSENSE TRM Audio Streaming Bluetooth Transmitter
2. SoundPEATS QY7 Bluetooth 4.1 Wireless Sports In-ear Stereo Headphone with Sweatproof Earbuds.
I found both on Amazon.
Hope to save all that looong cord problem!
Thanks to Strubie above for the idea!
When I receive these BT items, I will update this forum.
