Mechanically these seem to work just fine. The inside barrel unscrews to reveal a hole into which you feed your wire. It would be difficult to do a through barrel attachment of the wire, so these may not be suitable if that is important to you.

My biggest complaint is that the color was inconsistent. The "red" ring seems to be red about 40% of the time and orange the rest of the time.

Annoyingly, the ring on the inner barrel (that nobody will ever see) is consistently a deep beautiful red. Unfortunately the barrels are not swappable as the front will not unscrew completely.

Works perfectly.

Fit nicely into a keystone plate, and accepts a bare wire in the back for connection to in-wall wiring, or can terminate and insert another banana plug.

Love these banana jacks! They worked perfect for the installation I did. Coupled with a six position wall plate fitting one f-type insert one cat6 punch down two pairs of these banana jacks. Well worth the money. Thank you Monoprice.

Works great. Wise available in other colors than white

Easy to install and looks good... color is more on the orange side but you can tell that it is meant to be the positive connection.

Works as expected. Exactly what I needed.

PROS: Fits perfectly in the keystone faceplate. Gives a secure connection to the speaker wire.

CONS: Nothing that I can see.

Allows me to installed speakers anywhere I want and provides the flexibility to change equipment down the road.

PROS: Very inexpensive and easy to use.

CONS: none

these were exactly what i needed for my hifi setup. i threw a couple of these in a surface mount box and stuck it on the wall for a quick install. i have not done any rigorous signal loss testing. they work 10/10 for my purposes, though.

PROS: cheap, easy to use

CONS: none so far

Great quality just as good as the same jack sold at big box stores.

PROS: Works with "keystone" plates and devices. Cheap and high quality. Nice looking.

CONS: none!
