What's the most overrated or overpriced piece of equipment you own, have owned or come by?

One poster said no one here ever admits to owning Bose.

I own a pair of Bose noise cancelling ear buds, which I use on airplanes. And they are EXCELLENT for what they are designed to do.

Are they high fidelity? I have no clue, but they do cancel out a ton of airplane engine droning, and makes flying more enjoyable. Not only not overpriced for what they do (costs less than a decent interconnect), they actually work as well. 

On on the other hand, is there any Bose equipment in my home setup? Uh, no. 

I suppose ex spouses would be off topic 

The only item that I've purchased that ultimately proved a disappointment was a Thorens turntable in bought in the mid 80's. Motor issues and tonearm bearing issues were routine. Admittedly it was not a very pricey table, and I did have it for about 5 years. Sold it and bought a Rega Planar 3 which was problem free. 

I did did have a California Audio Labs CD player that needed several warranty repairs. Without jinxing anything I would say all my present gear has been quite problem free. For instance, I've had my turntable for 18 years now and it has never needed any repairs.
