Product Description
Optimized for travel and uncompromising audio, the Etymotic ER4-S Micro Pro Earphones are a great choice for audiophile-grade listening on the go. Made from thick, sturdy plastic, these earphones hold powerful balanced armature drivers that deliver crisp, extended highs, energetic mids, and booming bass Read More

in various other locations on the web, the ER-4S is described as "not good for mobile devices" presumably because of the impedance. Is that correct? I hate to say this, but my primary use for these would be with an iThing, and I don't have the time/patience for faffing with an external amp. My primary goal here is to upgrade from an ancient and failing (ten+ years at this point) set of Etys that provide me with superb noise isolation while I'm in my woodworking shop but I still want enjoyable music and not the deafening roar of saw/dust collection etc.
@PACoug Thanks for the info: I will look into it.
thanks @Jackstraw335 I was hoping for the higher end performance from the ER-4's, but having done more reading: turns out there's a specific version of the ER-4's for iThing's :) Something to keep an Eye on 'Drop' for :)

The best headphones ever made and still popular now while outperforming new IEMs. The only company giving real studio sound with actual science behind it. While others just overhype and how it outdated than give a real challenge, Since the few that sound better are £1000+. Never understood the hate with BA drivers when in my view there on par with good planar headphones. Never understood the obsession with THD when there no proof it will hinder clarity, Since the last time a A/B was done only few could tell. lol <1%( 0.1 ~ 0.95%) Distortion at 100db that still better than many studio speakers and most headphones that hype there drivers. lol

ER4... one of the best series of earphones ever made. I am still using a pair of ER4B from 2012

Is there any advantage to these now that ER4SR/XR are out?

I HIGHLY recommend that you spend the $ to get custom ear tips made for these. Unless your ear canal is perfectly round like stock tips, or really close. The tips will work on almost any ETY earphones, I used to swap mine from the pricey 4 models to my cheap models for travel and then back again. I now have a set of custom tips for each of my 3 Ety earphones, cheap, mid-price, and E4-S. Huge bass improvement. Better presence. Better seal also helps with not needing an amp. My ear canals are tall rectangles, so I always had to choose between good but painful sealing, or comfortable poor sealing. Cost isn’t that much compared to the huge leap in sound quality. Instructions Can be found on their web site... for years, they subsidized the cost if you owned certain models (how I ended up with three sets of tips.) No more, but absolutely worth the cost.

EdinNJok I checked: no detachable cable. Sadly that’s a no from me dawg. How do these compare to any of the the ERxSE series? I have a pair of (failing) ER3SE and the PTO, thinking if I should spring for the 4SE instead.

blackswanSadly, I've had terrible experience with non-detachable Etymotic cables in the past. These are a different class I know but I got through 4 pairs of HF-5s in 2 years which all had the same issue. The cable simply perished. They replaced the first two sets under warranty and the I paid to replace the third set as an out of warranty replacement. I asked at the time about upgrading to ER4, mostly because of the detachable cables but, at the time, they weren't doing the "Trade-up" program so wouldn't let me. When the same thing happened with the fourth set I vowed never to buy another pair of Etymotics despite how good they sound for their price point.

Just want to say I've owned the 4S and the 4P, still do. These things are godly, they are accurate beyond belief and I still prefer them over some of the more expensive sets I have (cough shure, sennheisser).
That said, they are known as "ear rape 4" because of the fit, and the S requires an amp. Though you can swap the cables easily enough to get around the amp.
Best IEMs you can get short of customs.

frontsidebusAny link to acquire said P/PT cable? I'm not sure how my iPhone will drive these (I hear not so well). I don't mind the "ear rape", I use a pair of HF2 and also have a pair of EtyKids 3. Lol.

Wish they had offered the ER-PT instead.

I think he was talking about getting a new cable altogether.

Nope, the drivers are identical. The resistor is in the cable, right before the Y split. That is why the cable is huge there.
