There's so many custom stuffs in the pic, LOL. The tips are actually from my BLON BL-Mini, S sized. And I matched and hacked it up with Shure Tri Flange stem to fit ER Series nozzle. The cable is custom DIY I did myself, again hacked from TRN OFC cable and re-terminated with aftermarket Chifi MMCX Beryllium plugs. Finally the plug is 2.5mm balanced plug, aftermarket as well. And of course the 2.5mm is mated with another custom 47 Ohm SE adapter

Thanks for the details. The personalization is amazing. I won't have enough talent to do the same. Thank you.

You can still get er4xr for $129 in adorama!

See if you can import them, that should still make it way cheaper than €400. Also er3xr is $80.

From all the post from before, they seem to be quite close. And with an adapter to add resistance, you can make them more or less same. Hope this helps.

Wow thanks for the link! Was on the fence between 4XR and SR on Amazon but that price sealed the deal for XR.

Really love the ER4SR/S vs ER2XR impressions I see on Reddit. The ER4 measures <0.3% nearly full range at 100db, Yet everyone acts like it rates 5% from 20 ~ 350Hz. When oratory1990 ER4 profile that uses a 10db 155Hz low shelf there no extra rise in distortion, They start lashing out despite being told how IEM driver are different to full size & speakers for how bass works. Been using a 6db 120Hz Low shelf with the upper mids tamed & boost in the treble, To turn it into a BA ER2XR but brighter.

I notice on Etymotic website, they changed all the specification of the sensitivity, from previously per 100mV now per 1mW. But the dB value is still the same from previous value. Like last time it was stated 96 dB SPL @ 1kHz, 100 mV, now 96 dB SPL @ 1kHz, 1 mW. Any idea why? The SPL value supposedly different per 100mV and per 1mW on calculation.

Even in the ER4 certificate they use mV for sensitivity, no mW.

Any idea why they changed it to mW?

Any aftermarket balanced cable recommendations for the ER4's? Only ones I can find so far are these from AE:

That one looks much better! Thanks

Is it just me or do these remind anyone else of the Blessing 2 with the AutoEQ preset in Wavelet? Sounds eerily similar.

A lot don't like being told the Single BA ER4SR can output the same bass as other IEM's that tout 10mm Woofer DDs with low shelf EQ at 79 ~ 190Hz. Same with mids/treble(ER4 peaks at 18.5KHz).

I don't think the bass impact quite hits the same. But I find the bass to be pretty good even without EQ on the SR. Don't find it lacking at all. With AutoEq, I think they sound almost exactly like the B2 without some of the midbass "thickness". I actually prefer this sound over the B2, I think they do vocals even better and perhaps slightly more resolving.

Blessing 2 close to Harman Target, and autoEQ in Wavelet make every IEM become Harman Target

@EtyDave Asking this may be a long shot; where is the "inaccuracy" of the ER4 SR situated?
a) Is that a part of the frequency spectrum,
b) a distribution over the whole frequency spectrum in which most data points fall (or are calibrated to),
c) both a) and b),
d) none of the above, but instead the following: ...[please elaborate].

Ultimately, nothing is 100% accurate. Dialing in any earphone acoustically to absolutely match a target curve is nearly impossible. And even if it did, manufacturing tolerances will always exist. When you consider the driver, housing, acoustic damper, assembly, there's always tolerance stack-up to consider.

As far as the inaccuracy, it's spread a bit here and there, but most of it is above the 2.7kHz peak.

@EtyDave Thanks for replying explicitly, I would have guessed that most/larger inaccuracies/uncertainties are found at the extremes; also the low-end. Is that then not really the case?
I would expect you to have a RMSE around the target curve to match the uncertainties in fabrication to, or are you matching the lower harmonics first and foremost (I figure upper frequency range error accumulate from there?)?

Hello everyone, I am now looking for a new set of black foam eartips, lately they seem to have a problem with the stalks becoming unglued from the foam
and also, they've become harder and harder to find since the last time I've bought them? I'm living in Eastern Europe and I can't find a European supplier for them anymore

Where can I buy a new pack of them which doesn't involve shipping from Amazon in America?

 

[carmatic]

On to a related question... I resorted to buying the black foam tips with Amazon, and I happened to spot that https://www.amazon.com/Etymotic-Research-ER4XR-Extended-Response/dp/B01GW786B4 the ER4XR is being sold for half the price... is this legit ?

The seller is legit, so is the sale, but the list price, as usual, is pure fantasy.
