Ety ER4P - how do they sound WITH an amp?

post #1 of 20
Thread Starter 
I'm curious to know how these sound when amped. I want something I can use unamped from time to time, but want them to also sound good when amped, and I don't want to pay $60-65 for the ER4P to 4S adaptor.

Can anyone give some detailed descriptions of how the 4P sounds when amped?

Er4p's don't need amplification. Why do you feel the need to amp something that needs no amplification? That said, they'll be louder with an amp.

They don't need it, nothing really does, but if you know anything about amps (im not saying you don't, and by the looks of your sig you do) you know that they make the sound "better" most of the time. Mabey he wants the lower end to extend more or mabey he wants a warmer feel. People use amps with very cheap headphones, that doesn't mean the headphones don't need the amp.

Doesn't the Xin Supermini have a 75 ohm setting which would avoid the need for a cable?

Every phone needs amping.

Well, does it NEED amping.. of course, no amping, you'd never hear it.

Does it need an external, large, cumbersome, expen$ive amp? Not in my book.
Any IEM will sound just fine out of a decent headphone out from almost any of the usual DAP's mentioned.

Results of mini-test

I normally listen to ER-4S and not ER-4P, but I did a mini-experiment to see what I could tell you. Just one track, Massive Attack's Protection, from iPod 4G into ER-4P, unamped and via Go-Vibe V5.

There's no question that amplification helps. The intro to this song features strong bass, some hard drum hits, and a little bit of tricky cymbal work in the background. With the amp it sounds great. Without the amp, here's what happens:

- the strong bass notes sound "pooped out" -- the way you might sound if you tried to sing a few notes when you were out of breath from running: maybe you'd hit the notes, but the the diaphragmatic support, the clarity, and the power aren't there.

- the hard drum hits have no sharp strike; they're there, but without exclamation points or emphasis. It's like the drum version of Ben Stein saying "Bueller...Bueller..."

- the cymbal work moves from the background into more of a front-and-center role, since it has so much less to compete with.

Don't get me wrong, the ER-4P really does sound good unamped. But it's very much worth adding an amp to if you have one handy.

The problem, although it's not really a very big problem is that the ER-4ps are very picky amp-wise. Anything like a PA2v2 or a LDM+ will not improve its sound, it will acutally take away from its cleanliness. I woudln't recommend going with anything less than PINT-quality.

they may not need amplification, but on something like an ipod, the line out through an amp will sound better than say, the headphone out straight into the 4P (I would hope).

I'd be using them with a Hornet, which doesn't have the ohm setting, but does have the gain setting which I could set to "low" to use w/ the 4P's.

How would a Hornet do with them?

As I said, I don't want to drop $60-65 on a conversion cable. That price is just a little too steep for what it is.

ttvj sells it for $40 new if you're a first time member or for $50 if you're not

You could get one alot cheaper than that, or even cheaper, you could build one yourself. Search and there are numerous people who have built a P-S cable.
