Product had a bad smell

These are not correctly advertised. They do not fully cancel sound. They merely dampen heavy echos. These are for big theaters or orchestras, not for household use. I bought with the intent of not disturbing the baby at night. It doesn't work for such things.

But it was so compressed it's nearing a month now and the end on some them are still compressed

They smell like dead fish and it never went away until we threw them away. They are thin and just not worth it. Invest in some good ones. These aren't it.

When it arrived, it was vacuum sealed as expected but after taking it out of it’s vacuum sealed bag and waiting over five days for them to fully expand 60 of the pieces still have not expanded and are still completely flat or half flat still. I have a feeling they will not expand since it has been so long waiting and since they are still so flat

I waited two days for them to expand it didn’t work I recommend to dip them in water👍
