The Koss will be a bit smoother and not quite as detailed or impactful, but still pretty close overall and very transparent sounding.

You really think it's close? Never heard the Koss but that's surprising. Tempted to pick up a set for my other desk

Yes. I recommend using the velour pads that come with the Drop version and making sure you get enough volume for them to sound good.

I own both the Koss e-stats and the SR-007 Mk1...there is no comparison. With a really good amp (I am using a WEE and 75-watt speaker amp) the SR-007s blow the Koss away. Much more detail, better bass, and a much more airy sound stage. Don't get me wrong I do like the Koss, but there is a big difference for sure.

Hello everybody , a new user of ESP95/X here .

It's really enjoyable to use this pair of headphone . The voice , and the musical instrument is really outstanding when compare to my previous headphones .
(Sony MDR-7506 , AKG 701 , Ultrasone HFi 760)

However , after a few days , I notice that there is some high pitch noise which irritate me .
I'm currently using a Cambridge DACMagic 200M .
My first through is that the problem is caused my poor soldered XLR > RCA cable .
However , after shutting down the DAC , the high pitch noise still exist . So maybe it is the noise from the AC adapter ?

So I'm considering to get a linear power supply . However , there is no way to confirm that will eliminate the issue .
Instead of buying a new power supply , I've bought a USB to DC port cable and connect to my power bank .
Lucky , it works , and the high pitch noise is gone for now (just tested for two days) .

So I'm going to get a new power supply now .
However , a new question is here .
Should I get a 9V or 12V power supply ? And the output should be 15W or 25W ? All these configuration are the same price .
Would anyone give me some comment on the power supply ?

Thanks very much (and also sorry for my poor English) .

Thank you .

So is it the best to use the default setting from Koss ?
As I've heard that some owner using a power supply with 12V output ,
I wonder if I should get a 9V or 12V output to get the best performance .

Best regards,

12V will most likely damage the energizer over time.

I use a iFi iPower 9V. After some blind tests with a friend, we both found it to give a little bit more defined bass and overall better sound.

Hmmm , you are right . I didn't notice this issue .
So I'll try to seek for a good 9V power supply .
Cheers !

It looks good ! But what I nervous is that my AC power strip is "contaminated" .
If using the same type of power source , the high pitch noise will exist again .

Usually a high pitched noise is the result of dust being trapped in the driver of electrostatic headphones.
If it is actually "contamination", try moving anything wireless away from your power line, like cordless phones and other adapters.

Can the E/90x unit be run directly from a computer motherboard via 3.5mm or does it always need to go via DAC? My cans are arriving soon and I would like to try them on my PC without shifting a lot of audio gear around.

Your computer has a DAC. You can use a 3.5mm to dual RCA splitter.

True I meant separate DAC but yeah, doesn't the energiser have 3.5mm input on the front? I don't think I have 3.5mm to RCA on me atm.

Yes it does, and I've used it from phone and PC. It works, even if SQ is far worst than a proper DAC.
