These work really well and fit everything including hard to fit short headset jacks like the Drop PC37x. Got the plastic ones too and they haven't had a problem either, but these feel more substantial.

It works fine. I feel like this kind of component either works or it doesn't. I'm not sure why I'd give it anything between 5 stars and 1 star.

It’s a pretty simple device, so not much to go wrong. It works, it looks good and it was only a buck. Hard to go wrong here. Buy one!

Does what it's supposed to, and solid construction ensures it'll keep doing what it's supposed to do for a long time. Five stars.

No me gustó en realidad en la foto se mira diferente y no fue muy costoso por eso no lo regrese

Everything as expected. Great products.

Perfect to allow me to plug headphones with miniature jack into electric piano with 1/4 inch jack.

The 3.5mm input is very loose on most of my headphones. The connection is intermittent to the point of being next to useless. A shame because monoprice stuff is usually close to perfect. I think it needs tighter spring pins/clips internally.

Does not stick well with my Bose 25.

Solidly built - these are the best I've found.
