The ER-4s has a nominal impedance value of 100 ohm compared to the 27 ohm of the 4p, which mean that the 4s will be significantly harder to drive than the 4p.

That said, 100 ohm isn't impossible to drive with a portable, though it might not be at its best without the benefit of an additional amplifier.

If you plan to drop some cash on an amp, then the 4s should be a safe choice, but if you know you don't ever want to use an external amp, then stick with the 4p just to be on the safe side.

What's more, you can convert a 4p into a 4s should you want to at a later stage, but not vice versa.

WTF?!?!?! US$40 for shipping a small little box?!?

What, they overnight it to you or something?


@yanjinowa,

If you're interested in getting the ER-6i, then go to either headroom or earphonesolutions and try to get them to price match with Buy.com's USD81 (plus coupon) offer. Plus shipping, it should set you back around USD100 or so, unless you plan to load up on filters/tips/etc.

I think the ER-6i is a great way to get to know if you dig IEMs at minimal cost. It's good enough to tide you over if you like it before you start itching for the ER4 or higher, plus if your source is less than fantastic, it should be as far up the ladder you want to go before LDMR starts to skew things towards cost rather than benefit. And if you find that you don't like the whole 'sticking things into your ears' business, you'll probably find that it'll be easier to offload RM400 earphones than RM800 ones

How big can the box be? I've seen the ER-4s retail box, just a little larger than the one on the ER-6i, and it can easily fit inside a padded envelope.

Don't tell me they try and stuff it inside a Jumbo Box?!?

Find what? The Er-6/i?

If you mean those two, scotty the moddy is selling them so click on the link under his posts to find more info.

As for the ER-4, nowhere that I know but I'm sure if you talk to scotty that he can probably hook you up with a pair.

If you plan to order them online, check out HeadRoom, Earphonesolutions, DiscountHeadphones, etc.

I saw both the ER-4 and ER-6i in Bangkok and the retail box didn't look all that different. That was when I wondered how tiny the ER-4's toolbox must be to fit in the same box.

Of course, I didn't bother to look too long since they were going for about 7500 Baht just for the ER-6i

No worries. Online purchasing is as safe (or as risky, depending on whether you're a half full/halfempty kinda guy) as retail buying, if you take the proper precautions.

I buy most of my gear online as it's often cheaper even after you factor in shipping and most times, I find it a lot easier and more convenient.

All audio equipment is taxable in Malaysia.

If it's sent in via FedEx/DHL/UPS/couriers, chances are you might get hit with import duties (round about 10%, IIRC).

Packages via mail rarely, if ever, get taxed but takes longer and are at higher risk of getting tampered with or lost (though it's never happened to me before).
