[EX Q]: Definitely not worth the money. They overheat and burn my ears very quickly after being turned on, the battery life isn’t more than 30 minutes, when trying to watch a show or video the audio is very behind and they have this constant beeping/buzzing noise while they’re on that you can still hear over your music.
[EX A]: negative

[EX Q]: I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.
[EX A]: positive

[EX Q]: I am extremely upset as it was shipped without being properly packed. I received the product without being wrapped which can not only damage it as it was mentioned to be a surprise to someone in the house and it was a bummer that the seller couldn't bring themself to put inside a shipping box so only whoever bought it would know what was inside.
[EX A]:
negative
