Got this about a month ago so I can use an external mic with my macbook. Its really nice, works great.

Clean output from a Mac Mini M1 to power amp - No issues at all. Biggest surprise was how good the output from this little beastie is.

Good little connector, enable my Macbook with a broken headphone jack to have a gaming headset. Very efficient delivery.

This item works as expected. The price is also reasonable. The only downside is that the two jacks are a bit tight, so you always wonder if the earphones plug has been secured.

I bought 2 x of these. They did work, but I could hear a background noise, quiet but still there. Other similar devices didn't have this noise. So I am not using both of these.
