... in my dad's basement!

Those will last me from when I get my mini amp to when I get my livewires I believe!!!

I've never heard of this Sennheiser, can you post some pics?

 

[Khanate]

Well I don't have a digital camera but I found a picture, they're the ones in the back:

They're about 25-30 years old and have an impedance of 2000 ohms!

I suppose they are related to the HD-414 then, interesting. An upgraded version of it perhaps?

One of the many variations on the original Senn HD414. With serious amplification (and I mean more than almost any current headphone amp can give), these should sound very good indeed. Out of your mini, they should sound alright but a little thin. Still, a nice pair of vintage headphones. Nice find!

Yes, I can't wait to get my mini-amp to try these out!

I've only heard ibuds so far and I think these will give me the crave for my next headphones!

That high impedance really f---ks the sound up. However you can get the amp to perform better with them if it sees a lower impedance, eg. 40 ohms. You could either run a 40 ohm resitor across the + and - terminals on the headphone or you could do this in an adapter. I once had a box built to do this for various dynamic phones.

That's mine! (posted with a previous nickname)

Yup, they are an improved version of the HD414, same drivers, but a bit different housing and driver nearer to the ear. I've never listened to the HD414 but the HD424 is supposed to have a better bass and more plesant overall response. Old school but still pleasant to listen to.
