Bought a pair of those from Amazon last year for $35 or so. I picked up another pair yesterday for $27.44, like you did.
From what I can tell, the difference between those on amazon and these listed here is; these have an "auto shutoff", they have the silicone rubber headband wrap, and they have the stupid cutesie "send it" on the side. Other than that they seem to be the same entry level Walker's headsets.
The auto shutoff feature would be nice, and should be on ALL of them IMO, as I have forgotten to shut mine off, and have killed the batteries before. (Now I have a label inside the case "TURN OFF HEADSET" reminding me to turn them off, and I keep spare batteries in the case also) I can't imagine that the silicone headband on the ones in this listing don't snag hair. Not a real big deal for most guys, but if you're taking your girl with you that would probably get old pretty quick if she used these regularly.
Here's the case I got from Amazon for mine. Works so well that I bought another for the latest pair.

Apparently Walkers makes an almost identical case. (Didn't see this last year)
