Was this Koss ever made

[JadeEast]

Does anyone know if this headphone was ever commercially produced?

Never seen that specific model, but Koss does have a dual element can coming out shortly...

It looks like the Porta Pro.

Yeah, they have a dual element earbud + supra headphone coming out, can't find it on the website.

Could be very interesting if done correctly.

just get a pair of PortaPro and some Koss earbuds and........I'd better don't say too much now....

Since Koss phones have lifetime warranty, such intricate design probably won't see production. There would have been so many of those little ears falling off and cause a warranty/service disaster.....

I have an earphone that may be based on that patent... it's called the Koss KDE/250, and was previously prototyped at the KDE/123 I believe. It has 2 dynamic speakers, and is my musical phone (coloration, enhanced bass/treble, ect.) I think it's great for the price, there's not really any other phone like it except for the Radius DDM, or the Phiaton PS320 if you want something bigger.
