What is the Silliest Accessory You Have Ever Seen.

Why would anyone care about such a test?  If the test is positive, and there is no audible improvement, no one would care about such a product, and if the test is negative and a number of people report audible benefits, no one cares about the test.

That is one heck of a stretch on human behavior.

So, @tweak1 brought up the fabled Clever Little Clock earlier in this thread. The original CLC was a Timex travel alarm clock with an orange dot on the face. Something was definitely very, very clever, but it wasn’t the clock. Rivaled only by legendary products of marketing genius such as the pet rock and the Power Balance wrist band, the CLC garnered almost universal praise from both professional reviewers:

I found my entire listening experience to be much more enjoyable with the Clock in place.....Machina Dynamica sells the clock direct for $199, and it’s well worth the price.

as well as from audio aficionados such as tweek1:

I have been using many Machina Dynamica tweak products to great effect over a decade, including the Clever Little Clocks, and yes they too perform as advertised. If his products don’t work for you then look to your system, or maybe your hearing is not capable, but his products work well.

I always appreciate when any dissention is preempted by, "If you cannot hear how great this product is, the problem is either "your crappy system or your crappy hearing" or, one of my favorites, "you obviously don’t know how to listen critically."

If you do some sleuthing, you may learn the clock has origins beginning with the "Dawn of Man" and is tied to a person’s internal clock survival mechanism that helps to locate predators. The clock addresses alien time coordinates that are contained in a recording and are associated with the 4-dimensional spacetime coordinate system (x, y, z, t), where t is the time of the recording session and t-0 marks the first instant of the Big Bang. Easy peasy....pretty basic stuff. Apparently, it’s the relative difference between Past Time (i.e., recording time) and Present Time (i.e., listening time) that’s important - and that is where the CLC come in. If you happen to question the lineage of the CLC, consider that:

The Clever Little Clock is based on concepts and techniques that were developed by PWB Electronics, Leeds, England and is designed and manufactured exclusively by Machina Dynamica. The Clock I currently produce (with the permission of PWB) is an "updated" version of their original clock and takes advantage of many newer PWB concepts/products that have come along since then. May Belt of PWB Electronics provided assistance with this theory of operation.

Wow, good to know. Don’t be fooled by substitutes, and don’t be concerned about availability since there is now an Ultra Signature Version of the Clever Little Clock (a Casio with a thermometer and two neodymium magnets!) for only $299....now that’s darn clever!

Do you guys ever take a break and just listen to music?

"What is the Silliest Accessory You Have Ever Seen."

Proponents are right, mijostyn formed the question wrong and it is not only because he did not put question mark at the end.

Reading about Hallographs, I get an impression they are not an accessory after all. They seem to work as a crucial, centerpiece in fact, part of an audio system. They simply do not qualify for this thread about accessories.

@glupson, are you ever wrong? 

I need to stay up later at night, missed a lot of fun. 

What is the dynamic that make us so gullible when it comes to audio quality. Why does all this junk always make things sound better and not worse. Why are there always some people who are unable to understand that their hearing, all of our hearing is excellent at playing tricks on us. Seeing is believing, but hearing is not. Hearing is a very emotional sense. If you hear danger you are in big trouble. We can see much farther away than we can hear 99.9% of the time. If you see danger coming you generally have a lot more time to deal with it. It is why we stand on two legs. Good thing Indians were scared to attack at night. 
Lack of understanding/knowledge and ego I think are most to blame. None of us likes to be wrong. Because most of this stuff does no harm (no benefit either) other than financial it is much harder to fault. 
I am lucky I suppose in that my own mistakes have always screwed things up enough to notify me that I had botched it. Certainly people with a better understanding of the science behind all of this are less susceptible to the chicanery.
When dealing with strangers it is always best to proceed with a high degree of suspicion. Someone who is for real knows this and will go head over heals trying to show just how good their stuff really is at shows and such.
You get up in the morning and check your email box 3/4 of it is somebody trying to scam you. It may be sad but you have to keep that in mind when dealing with strangers.
