Car horns
They are very loud as expected

Sounds like regular horn
They advertise this horn as train horn. I knew without actual powered air behind it it would not be that loud. But tried it anyway. It does not sound any bit louder than a stock horn. Total waste of time.

Not 300 DB
These are nice looking in silver. Actually look like chrome. I mounted them on my motorcycle which was not too difficult but required some fabricationMuch louder than a stock motorcycle horn but nothing more than a pair of car or truck horns. Not even close to anything like a train horn. Not bad for the price but I'm not overly impressed at all.

Good but not great.
Pretty loud. Louder than my stock corn but not as loud as I hoped for. I like it. I don’t love it.

Don't do it, they AREN'T loud.
The horn once installed, is not loud at all. They aren't even as loud as the original horn. Got these as a gift for my bf,very sad that they weren't up to par.

The horns sound good and are loud enough.
PRO: The horns are well made, sound nice with both the low and high tones and are louder than the OEM single horn.CON: These are not plug and play as the 2nd horn has to be wired up into the electrical system.
