Query: Great earbuds - great value!

I have used my Jbuds with my Sansa C140 since Christmas. The earbuds that come with the Sansa (bought in August 2006) and the Sony earbuds(Son-in-law gave me)are not comfortable at all for me.I really like the Jbuds - worked well on my Southwest Airlines flight (the other earbuds did not) so I know the noise cancelling was pretty good since other earbuds have not worked for me on planes.The Jbuds are so comfortable I can wear them while listening to myaudiobooks and fall asleep!
