the series is refered to as the 'HP-1000 series'

Top of the line was the HP-1 with polarity switches.
Next step down was the HP-2, with the same drivers sans polarity switches.
Bottom can was teh HP-3, same as the HP-2, but the drivers were not always as closely matched.

Of those... correct me if I'm wrong... the HP-2 is the most common. Very few of the HP-3 were made, and the HP-1 less were made because of the complexity of the Polarity Switch construction... right?

Edit: Sorry, I didn't mean to hijack your thread. I just know very little of the HP series as well.



The headphones weren't made for audiophiles, they were made for serious recording studios. I believe (correct me if I'm wrong again) that if something on the recording is "out of phase" reversing the polarity can fix it, to listen effectively.

I would recommend reading the "Interview with John Grado" thread. He talks about the HP-1000's and their nomenclature and what not.

Funnily enough I was talking to immtbiker about the hp-1k series. We both agreed it's "better" to have the hp-2's. Why?

Because with the hp-1's we don;t know which way is the correct way to listen and that if given this option then it detracts from getting doen to the music.

Personally I can't tell which is the "better" way to listen to the hp-1's if it's + or -

Maybe immtbiker has better ears than me but I couldn't tell.

I agree with that! My eastsound also has the polarity switch, that makes 4 permuations. Does that mean I have to listen to a CD 4 times before deciding which one is the right polarity? And not all CD have the same polarity. how confusing

ok, correct me if i'm lost, the HP-1 HP-2 and HP-3 is marked on the headphone cup as HP-1000. You only know if it's the HP-1 if it has the polarity switches and if it doesn't it's a HP-2, but what if it's a HP-3? How does it look?

As long as you don't listen with one + and the other -

The HP3 has an 'HP3' sticker on the box and also,I believe,it's marked under the ear pads on the metal with 'HP3'
