I just recently got a pair of the Sennheiser RS 110s and I enjoy them. When I saw this deal, I almost jumped on it, after reading reviews that they're better, then the whole rechargeable factor. However, I decided to wait and see if RS 140 prices drop at all, as I would rather have close-backed headphones (my personal preference).
I don't know about the JVCs you linked, but I see nothing wrong with having a set of wired and a set of wireless headphones. I like to use my wireless when I'm cooking/doing dishes/etc, then wired if the actual cable doesn't interfere with anything.
