I stumbled across a deal on the Klipsch S4 ear buds today at Radio Shack. These are the original S4 model and Radio Shack has them on clearance. The store I was in had several pair available.
It appears that Klipsch has released a new version, the S4 (II) model to replace the earlier version of the S4.
Since this is in the process of happening, the Klipch S4 ear buds in the Radio Shack physical stores are being discounted for clearance at 48% off the regular price. This brings the price down to $41.## -- or, $41.00 and change.
I'm not sure when this clearance started, but if you desire these ear buds, might be worth stopping by your local Radio Shack to check out the deal. Unfortunately, I did a Web check of their site and the original S4 is no longer listed, so it's hard to check local stock for area stores since there isn't an item reference.
Again, since this is within the stores themselves, your mileage may vary. However, the clearance tag was printed out just like the other Radio Shack labels are for the other items that are placed on clips in the display areas.
