If you still love Etymotic ER4, this is the thread for you... - Page 272

post #4066 of 4784

So I'm searching to match a 70 db volume.... I have an etymotic er4s with 100 ohm impedance and 100 db per 1 mW. I'm using a fiio e07k with 220 mW@32Ω and, 250 mW@16Ω... I'm using gain of 6 dB (2X) and i'm asuming 2.7 V for the e07k before the gain. So without gain it will 118.62 db max loudness and with gain 124.6434 db...Is this correct? With gain of 6 dB is just multiply 2.7x2=5.4 as new max ouput from the amp? Since the e07k has 60 levels for volume i'm just using proportions to match the desired decibels... but when using equivalents for 70 dB with and without gain it doesn't sound equal... Any help will be apreciated

Wow. The new album from my favorite band/duo. Sounds amazing even on youtube. Wow.

Reference stuff right there. Every nuance. So beautiful.

Yes luisdent, very nice indeed.

The way ER4S keep coming back to surprise me is quite rare amoung all the IEMs I've owned. This pair have paid for themselves 100 fold on an enjoyment level since I picked them up second hand. They aren't necessarily the best sounding IEM I own though certainly the most consistent.

I agree - I just got the JHA Roxanne. After sending it back for a refit, I started using the ER4S. I exepected to be let down, but I was still blown away by the detail and linearity. Its still the best bang for your buck out there.

Got an email for the repair on Friday:

 

Evaluation Notes - Left pod(264) stem is broken at tip. 


Our Service Technician recommends replacing the transducers on this unit (new receivers, filters, and eartips).  All components are new.  The cost to complete this repair is $85+ shipping.

 

And they are already on there way back to me!

Can the Roxanne, with bass turned down, get as close to neutral as the ER-4S? How does its treble sound in comparison?
post #4073 of 4784
Not really. The ER4S is more neutral. The Roxanne's have a "thicker", warmer sound overall. The treble is different. It's a bit laid back on the Roxanne's but also extended.

I've tried the JH13 Pro universal demo and it has a thicker sound too but has good high frequency extension. The bass frequency has a very good impact. ER4S seems to have a flatter response though, even with a lesser impact on the bass. It sounds less accentuated at the bottom end.

Relatively easy test to pass, albeit spending some time and effort and then we will all know what "our" fundamental  base is or where we are coming from... weaknesses vs. strength, maybe none at all..

Yes, I've completed the full test in one go about a month ago. Thank you :D

post #4077 of 4784

I'm so distraught that I hesitated on these for so long. Whoever says these don't have enough bass is crazy! It has an adequate amount when deep in enough, but it never bleeds into the mids. I can hear everything, it all sounds so crystalline! 

 

TL;DR: I'm in love.

 

 

Also, with a 75 ohm adapter, these things are little power hogs aren't they?

post #4078 of 4784

Yep, they need an amp in the "s" configuration IMO

post #4079 of 4784

would be nice if those ebay adapters came in various resistances.  I would choose 50ohm instead of 100 and get a bit of a compromise in linearity vs power output.  I really hate carrying around a portable amp.

post #4080 of 4784

Has anyone tried the E12DIY w/ the ER4S? I'm currently debating between that and the C5. Doesn't seen like there are a lot of options between 100-300 to consider that can match up the ER4S' ability to retrieve detail and their neutrality.
