Any suggestions? Isolation is my biggest concern, a well behaved treble and a decent bass response would be a distant second requirement. Considering the price difference which should I go for? 

ER4PT = ER4S and ER4P in one package. ER4PT without included resistor plug = ER4P and ER4PT with included resistor plug = ER4S

 

 

I don't know why people keep saying this?  Did you get a resistor adapter with your er4pt?

 

"What's in the Box

ER-4PT earphones, 1/4" stereo adapter, airline adapter, 6 pairs of ACCU-Fit eartips, shirt clip, replaceable wax filters, filter removal tool, channel-matching compliance graph, travel pouch, and storage case."

The "T" is for the travel/airline adapter.  Not a 75ohm resistor adapter.  ER4PT should equal ER4P with airline adapter not ER4S.....

Isolation wise SE535 is no where near ER4's level of isolation. This is my personal opinion after spending an hour or so with the SE535.

 

Isolation of the 535 isn't bad, but 10db more with the er4 can be a huge difference as well...

Of course it does luisdent, if not I wouldn't have even mention it. My ER4PT comes with the resistor adapter.

 

"What's in the Box

ER-4PT earphones, 1/4" stereo adapter, airline adapter, 6 pairs of ACCU-Fit eartips, shirt clip, replaceable wax filters, filter removal tool, channel-matching compliance graph, travel pouch, storage case and the 75ohm resistor adapter". Yes, the 750hm resistor came packaged in the ER4PT box. I didn't purchase it separately. In fact that's the reason why I bought ER4PT instead of ER4S. When I want to listen straight from my iPhone 4S I use ER4PT without the resistor adapter. When I'm mixing my music I use it with my resistor adapter through my MOTU digital audio interface at home or the Yamaha 02R/96 mixer in the studio. I normally cross check my mixes between the ER4PT and the Yamaha NS10M studio monitors.

 

Here's the picture to prove:

I concur.  I'm selling mine and when I received it, it came with the "S" adapter, but this particular accessory is NOT called out on box "In the box" list.

 

However, I do recall my first ER4PT purchase from B&H about 3 years ago, it did not have the "S" adapter, but everything else are included. My guess is the difference with the batches where some excluded it, but most didn't.

Probably so alpha421. I guess all their new batches are packaged with the 75ohm adapter. I received mine last year with the adapter therefore any ER4PT a year ago should come with the adapter except some stores stocking previous batches (more than 1 year) without the adapter. Therefore it is advisable to check with the store before purchasing it.

I am new to this thread, and there is no way I will be able to read all 275 pages, but I will say I have spent more than a week with no other phone in my ears (daily) than the er4s. What a treat! The midrange and blend into treble is unbeatable. Soundstage? Just slightly out of head. The naturalness of the sound is quite addictive. My th900's are slightly better and have better bass impact, but boy, for the price and size difference, these 'phones are exceptional. Currently using Amarra and it's 'bass boost' setting. Phenomenal.

on etymotic's website they note that some batches shipped were without the adapter because they were lacking stock at the time. if you didn't receive an adapter with your purchase you can email them and ask for one.

Well then all is good for all new ER4PT customers who's not getting the 75ohm resistor adapter in their package :D

Does anyone sell the adapter that converts P to B.

 

I'm not talking about the cable bundled with the PT but the DIY cable.

 

Quote:

4) S is the treble tuned down version of B. The difference b/w S and B is B has a pair of capacitors and resistor in the 'cable pod', while S only has the resistors but not the caps. As such, B can not be changed to S or P without changing cable.

 

5) There is a special cable by AW audio ('awwan' on eBay) that can let you changed between P, S, and B within one cable, but it is quite pricey. The way AW audio does it is by making a small selectable circuit board in the 'pod'.

 

I would prefer not to have to make my own but I will do so if no-one sells them any more.

 

Edit: I found their ebay page. It looks like they don't make them as cables but as small adaptors.

 

I was hoping to find the version that has all 3 on a cable with a switch.  I can't find the schematics of that one.

If you find it please let me know Dreyka cause I'm also interested. A small adapter that can switch between P/S/B will be so useful
post #4120 of 4659

It was talked about and measured here.

 

A link in the comments goes to this page. I think this is the circuit used.

 However, it has been proven quite tricky to turn ER-4P into ER-4B, since ER-4B has a dedicated high-pass filter(100 ohm resistor & 220 nF capacitor in parallel) implemented in its barrel.

 

 

The person was charging $250 for this adapter which is far too expensive for me to consider purchasing.

Thanks for the info Dreyka. Oh well, $250 is too expensive for me too...I'll stick to ER4P/S then. Just thought it'd be nice to try out how ER4B sounds like but not at that price though. I really can't be bothered.

When was the ER-4S/ER-4P released? The earliest thread I can find is 2001. I can't believe the design has been unchanged in 13 years. I would have thought balanced armatures would have improved in that time.

 

Edit: Found this PDF with a product timeline.

 

ER-4S/ER-4B was released in 1991. They are more than 23 years old.

 

Perhaps, we will see something new for the 25th anniversary. Surely, balanced armatures have improved in that time.

Nope. The er4s is still better than any other ba i've heard. Sad really. But also impressive.

So has the only improvements been more balanced armatures! The JH Audio Roxanne has 12 of them.

I think the main advancement has been fitting multiple drivers into earphone that still fit in your ears.  However, the sound doesn't necessarily improve with more drivers.  However, if etymotic took the er4s and added a sub bass driver that would be a pretty darn amazing feat.   If that would allow the earphones to not struggle in any one area and thus allow them to fine tune the treble even further (very slight), you would have the perfect iem.  Alas, I have yet to hear such an IEM.  I'm speaking of universals.  I have no desire to spend a lot of money on a custom iem i can't hear first and can't know how it will ultimately feel and sound.  And I've yet to read a review from someone who loves the er4s that describes any of them sounding better.  I think the technology exists to make a better iem, but no one has done it yet.
