Still enjoying my E95X binge while reading this thread. I am currently listening to a ton of U2, which is mostly quiet. Reading the previous posts I started wondering how weak this “amp” is. I listen at about 1/4 volume. I tried but can not get anywhere near 1/2 volume. I must listen to music at the lowest volume of anybody on this forum.:grin:

Lots of power for me and the sound is Great. One thing has become obvious to me though: The bass will never kick. I have maxed out the EQ and you can just hear the bass, if you listen for it. But that’s fine as they do everything else so well. Kind of similar to the Beyer T5p.2’s. However the Beyer’s will take some bass and the E95X just has a “Big” sound I have never heard in other headphones.

PS: Additional note. Listening to The Joshua Tree (remastered), the drums are kickin’. Does not feel AT ALL bass light with this album.

I have just purchased the Koss ESP/95X.

The shipping experience was
less than perfect, but in the end, they arrived.

I have read and watched all the reviews about these electrostatic earspeakers that I could find, so I felt that I had a good impression of what I was buying.

The unboxing experience is nothing worth writing about, and the build quality is described in plenty other reviews, so I’ll go straight to my impression of their sound:

I remember Zeos saying something along the lines of electrostats having a sound where everything apart from the bass is “layered on via magic”

I haven’t been “into” headphones and audio for more than a couple of years, and I’m starting to think that either my hearing is damaged or not “matured”, because I’m having a hard time being
THAT impressed with electrostats. I’ve owned the L300 with the SRS252 as well, and was not terribnly impressed by that combo either.

Granted, I’m “only” listening to Spotify Premium, but I also can not hear the difference between that, and DSD256. so there’s that.

I mean, they sound good
with some music, but I find them to be picky. They seem to like calmer music, and not so much rock and metal. I think they do not have that good of a seperation,
but I might contribute that to their not-overpowering lowend - since the higher notes seem to “bundle together”, and the lower notes have always seperated better in a headphone, to me at least.
I listened to a tone sweep on Youtube (without knowing if it’s actually that useful), but I seemed to be able to hear sounds fom 18Hz to 13kHz.

If you guys have some suggestions for music that you think will make the 95X blow my socks off, please do contribute.

My first listen, I was blown away by the sound and the detail. After several hours I did find the sound lacking on the bottom and the top. And then I discovered the magic of EQ’ing.

But others here may have more practical advice.

Seems like a lot of people like EQ’ing these.

Not to be ungrateful, but I really dislike the idea of EQ’ing - I prefer to enjoy the individual headphones’ sound signature. Otherwise, I might as well never buy another headphone and just EQ my way to trying other headphones. (simplified, but you get the idea)

No need to apologize! You gotta do what feels right.
I just use a little Schiit Loki and there is NO headphone it can’t improve, at least a little bit. And it is idiot proof. Four knobs and you’re done.

Perhaps the E95X is not for you. I am not sure I would keep it without the magic of EQ.

So, is there anything particularly “electrostat-y” over something like the Sendy Aiva?

An estat perhaps, it depends on what you define as “electrostat-y”

IMO
 compared to the Aiva, the 95x has a lot more ‘airy’ feel to it. Just super fast transient detail/ sound separation. It’s very different sounding from dynamic and planars in general. The biggesta caveat as other’s have said is the lack of ‘body’ / low end.

They sound real good with Blues, Jazz, vintage rock, all sorts of easy listening vocals, latin, greek, and russian folk, mamba etc. Not much bottom end to speak of they really taper off under 60hz without help. Depends on what you are used to tho, they are an old model estat, from what i hear the newer ones are more likely to blow your socks off, this is a nice piece for the money tho.

Could not agree more, I have to give them a shelf or peq sub 100 up about 4-6db before it fills out and gains the body needed. At that point it has great punch, but still is presenting the bass in a analytical way, not brute forcing it like a dynamic. Bass on a good planar I feel is superior, but not by much after eq.

Tried most of my ost, opinion hasn’t changed, but I notice that comparing to the 58x, it really highlights the differences between bright and dark songs because of how different the bass sounds as well as the clarity of everything else.

Cause I put some ost like Chrono trigger which has SO MUCH brightness in the instruments, it’s kind of crazy, MOST of the ost is improved on the 95x. There’s still some dark songs I prefer on the 58x, but it really gives me the idea of the difference between bright and dark songs which is kinda neat. Needless to say, if you listen to a lot of bassy stuff, it doesn’t seem to be a good choice, I might try EQ, but yeah.

Honestly, at this point, I am considering getting a jds labs ol switcher because I love to compare with 58x and I understand their differences enough to want to listen to both flavor depending on what I am listening and my mood. It’s just that rn, it’s annoying to have to move the rca plug from the energizer to the atom, etc


I will say this: if you listen to a lot of bright songs like orchestra with stuff like flutes, violon, cymbals or drums, it’s worth their prices. Now, I REALLY don’t know if I would be ready to pay 1k+ for a stax unless they actually blow my mind COMPARED to the 95x, but for the 500 usd (now 400) of the 95x, it’s perfect. You also get to have mind blowing openness with good soundstage without loosing separation.

Seriously, that’s what shocked me the most: NOTHING except terribly mastered songs was complex enough to show any limits to the imaging. It blows my mind because if you have good soundstage, it’s much harder to have good imaging because the directions are harder to tell: it sounds further away after all, but they are so good that it’s not even a concern.

I still maintain that they sound like as if they weren’t there: you just end up listing to the songs instead of the earspeakers (I will call them that because they are not lying to you).

And the thing to consider with stax is that they have an even less natural timbre and less bass, with a much brighter and airier sound. So for most music if you want it to still sound natural, the lambda series might not be an improvement over the koss imo. Just something to emphasize how good the 95x is for the price lol

Very natural sounding, I just sit back and jam for hours and hours. They are so open and transparent to me
 I’m even letting my brother borrow my beloved dt1990 due to how much I love these buggers!

Got mine today. They sound very detailed, natural but bit dry. Is there such thing as burn-in with electrstats? :smiley:

https://vesperaudio.com/earpads?brand=178

Which ones would you rec?

There really isn’t any burn in with an estat

I like the genuine leather+alcantara from them

a slight segway
