Well made but really light material
Rated 5 stars as I don’t think what I write is a negative to the product or company.This foam is super light so I feel it has heat mitigating properties and no sound properties but it’s also pretty small so it may be more of an aesthetic. The cost is kind of high but I couldn’t cut it myself at home. (Note - I only bought the window surrounds)I made custom jeep roof headliners via jeep diy and probably spent $40ish so I am appreciative I did that versus the hundreds for the full set of this product. If you have the money I’d get this but I like projects.

They do work
In combination with the roof Padding , they do reduce the sound and the temperature inside my jeep

tight fit
good fit for the side of the 2dr hard top but very sticky on one side. once it stuck, it is hard to get back off to rearrange the fit

Great product, good quality. Don’t rush the install.
I purchased both the design engineer ring 050138 boom Matt sound deadening headliner for two door Jeep Wrangler and the designer engineer ring 050152 boom Matt sound deadening side window trim kit for two door Jeep Wrangler. I can’t say enough about them. They are fantastic! They are not soundproofing, they are sound deadening. That being said, they absorb sound. They don’t keep sound from coming into the jeep. The music actually sounds better now because it’s more acoustically correct. The sound is not bouncing all over the cab. It was a little tricky to properly install however certainly nothing that anyone can’t do without taking their time. Don’t rush it, you don’t wanna do that. You Amazing difference in sound quality.don’t want to wreck one of these pieces because they’re pretty expensive. They are pretty darn good quality and again, can’t say enough about them.

Flimsy, completes the look with the headliner
Very thin, product stretches easy and wrinkles during install. Completes the look with the headliners.

Cuts road noise and helps with temp. regulation. Can't really ask for anything else
I have had these installed for about 8 months now, through a warm summer and now into the reasonably cold winter months, and am very pleased with them. There is a big difference with these and the ceiling panels installed, the road noise is much lower and the temperature in the Jeep is easier to control. Passengers in the back seat don't complain as much about being too hot or too cold or about not being able to hear conversation. I highly recommend the complete set, window surrounds and ceiling panels.

They work but ...
These units work but there is no rigid back so they are floppy and can bunch up during install. Hard to get edges straight due to flex. Would be better if rigid like Hothead. Good foam though, like I said they work.

Take top for best installation.
Deadens sound considerably.

They fit well, but thinner than I expected.
I bought these and hoped they would be as thick as the area allows 1.0". But they are not, only 1/2" thick.Will need to wait for winter to see if they are good or not...
