Quoted from docquest:I think the difference is that the one with the Stern logo sticker on the front costs $100, while the one with a generic sticker on the front costs $50. Functionally they appear to be the same.
Since there is headphone talk, Pinnovators would like to throw a hat in the ring too. Right off the bat, I will say our headphone kits are more expensive than the Stern brand or the generic one but we provide features not found on the others.
I'll highlight some differences on Pinnovators PinPAC 4 Stern Spike/Spike2 compatible headphone kits:
System Volume:
The Pinnovators kit allows you to quickly adjust your system volume whenever the machine is on. With the Stern brand and the generic one – you only get one way to adjust levels without having to open the coin door. Pinnovators gives you two ways to quickly adjust your levels!
Why does muting matter? It depends on your usage!
We all know that when you play with headphones on, you can be way more focused on your gameplay but what about if someone else is watching and they want to hear the game too?? With the Stern and the generic kits, you can’t change this option from the front coin door. With the Pinnovators kit you can quickly choose to have the system volume muted or not while you are using your headphones. You have options with Pinnovators!
Make no mistake, the mute feature of the Pinnovators system is what sets us apart from the others! Pinnovators was the first to use the Dollar Bill acceptor (DBA) plate for a headphone system and others borrowed our design.
Another cool feature is our Subwoofer Output Jack!
All our headphone kits come with the option of adding a subwoofer output. If you want to add a sub you just need to buy our cable kit ($10) along with the headphone kit. The reason we have it as an option is not everyone purchasing a headphone kit wants to also attach a sub.
No graphic clutter on your panel:
No decals on our kit! Personally I don't think the decals that are on either of the other kits are at all appealing. Ours is made to blend in with the coin door as we use an OEM coin door plate (except for our PinPAC 1). Again, it gives you options! If you decide you want to dress it up, go for it!
Custom chromed or colored coin door DBA kit mounting:
We also offer a custom punched DBA plate service for FREE! Send us the DBA plate from your coin door and we will mount our kit to it for free.
Customer Service:
We go above and beyond to help you make the best Headphone/Subwoofer decisions for your game, even if we don't have a solution for you!
Until Monday our PinPAC 4 SPIKE/SPIKE 2 is on sale for $108 (regularly $120), if you want the sub out cable kit with the headphone kit then it's $117 (regularly $130).

Here is a comment we got yesterday from a customer..."I purchased your headphone kit for my Medieval Madness remake and liked your version so much that I’m replacing the Stern version on my Ghostbusters and my Pinball Life version that is on my Jurassic Park. I think what you are doing with your integration is the best implementation. So, GREAT JOB."
