I cannot review on the longevity of these yet; however, taking care of them and in the plastic when not in use, these should last quite a long time.
Long plane trip with my kids, we could share audio and have our own volume control.
It works great!
People have different hearing levels and different headsets aren't as loud as each other, so it being able to each select your own volume is exceptional.Some cheaper or cheaper made (this is pretty dirt cheap) splitters don't have all the connections (count the segments on the plug, there are 4 here which is great, if there is less, you might have an issue with a phone or tablet).
Then for some reason the static started going away but at the same time my phone would give me an alert that this accessory is not supported by my iPhone and would stop working.
I know these were cheap and you get what you pay for, but I expected the splitters to at least last for the round trip flight.
Item arrived but didn't work, one side of the splitter only works in the right ear, not the left.
Tried with multiple headphones.
Tried to return it but looks like the seller doesn't take returns so I'm stuck with it.
