ISN Audio - EST80

Isn h60 and isn est80.

Okay, hey, it's a shame they're offering me the pre-sale discount on the ISN EST80. I'm suffering. I bought the Penon Quattro and now I don't have the budget to order the ISN EST80. I'm still thinking about asking my wife for the money, but she freaks out when I tell her the prices. She wants to kill me. Ahhh.

Hey, these things (Penon Quattro) are magically improving. I also swapped the Tangzu Sincai balanced eartips for the stock white and red ones, and the sound and dynamics opened up much better. And of course, I put Tangzu Sincai balanced eartips on the ISN Neo5s, and the soundstage increased. Thanks, and please let me know about the ISN EST80 when it arrives. I'm thinking about financing options. The yellow ISN EST80 has me completely insane.🤑🤑💣

Shit, my most expensive IEM is the ISN EST80, priced at $650, and it was pre-ordered with a $100 discount coupon, so I paid $550. Now I don't spend another cent. End game.

If you noticed the difference in audio quality, the thing is that personal tastes are subjective. I have the kefine klean for $49 and the most expensive ones are the isn est80 for $649 and there is a huge difference in audio quality. It's better to have one good IEM than several cheap ones. Sometimes cheap is expensive and expensive is cheap.

A wonderful IEM, very balanced, detailed, and musical, as well as beautiful, with very good build quality. It's an all-rounder; the ISN EST80 could be the end game.

Yes, it is a unique IEM, the only two drawbacks are the price and that they are a bit bulky.

I don't understand if someone says the ISN EST80 isn't that good; they're fooling themselves. The ISN H60 is wonderful, but the ISN EST80 is much better—it's on another level. The problem is the price, but it's currently discounted on AliExpress. Before making a purchase, do your research because what might be good for me could be bad for others. But ultimately, if you can't afford the ISN EST80, the ISN H60 is an excellent option.

The 80s aren't explosive, they're balanced, dynamic, and fun.

Between the QOA Adonis New and the ISN H2O, the one I listen to the most is the QOA Adonis New, but in general the one I use the most is the ISN EST80.

The ISN H20 is a superb IEM with deep, punchy bass, organic and musical mids that are somewhat repressed with a certain filtering of the low mids, creating a sense of warmth and weight in the notes without muddying the mids, and smooth, dark highs that complement the tonal balance very well. This IEM is more musical than detailed. The QOA Adonis New is superior and more enjoyable overall. The bass is deeper and more detailed, more defined than in the H20; the mids are present, organic, and dense with a certain level of detail; the vocals are prominent and sweet; and the highs are smooth and extended without being bright or sibilant. I don't listen to EDM, but in general, I prefer the QOA Adonis New, which is a very underrated IEM. The ISN H20 is very good, among the best in its price range.

Yeah, thought as much. Its a shame though, as others may not even be aware that these brands exist.  ISN H60, EBC80, EST80.  Penon Archangel, Voltage, Fan 3 Sound Rhyme DTE900, DTE264, SR10.  Earacoustic vsa pm crown.  All the above are fantastic iems from those brands, it's a shame that a of people aren't aware of them - as Penon and its sister companies probably give the best bang for buck out of most iem manufacturers (as a whole) excluding the likes of bgvp perhaps.  I used to follow Jay a lot, until I saw one Facebook post where he said thst the Unique Melody Maven II wasn't an alrounder... I've personally owned the Maven II in the past, and couldn't understand this at all - every other single review regarding those iems also praised them for their versatility. You got one person saying they're not an alrounder vs at least 30 who say they are 😅 it's going to raise some doubts..  The other was his take on the Annihilator, where he talked down to someone for being a "serious audiophile" basically just wasting their money. Funnily though, I also own the anni 23, and have yet to become across an iem that can deliver treble in such a smooth way as the anni can 😅 I'd love a cheaper iem, but no one to this day has recommended me a cheaper iem that can do what the anni does (yet it being ancient in the iem world)  Anyways, enough ranting - I hope people stumble across those brands that aren't talked about as much big the big reviewers. 

I haven't tried the ebc80 but I have the est80. It's also my first ever isn product. Sounds pretty good overall, has that W shape sound signature and well balanced across the frequencies. Bass is well balanced (for the most part), good texture and it slams and kick well. But it doesn't rumble as hard as the archangel, that one is a different animal entirely lol. Bass ratio for the est80 would be 45% subbass and 55% midbass. Midrange on the est80 better than the archangel imo. It's thicker, more forward and lusher whereas the archangel is neutral, balanced and accurate. Treble sounds similar as they're both energetic and well detailed. But the archangel has more air ironically due to BA drivers, whereas the EST drivers in the EST80 lacks a bit of air imo. But est80 trades the airiness for a smoother listening experience. So if you want a basshead set that sounds fun, versatile, neutral and more technical then go for the archangel. If you don't care about details and soley want a more balanced, colored sound while still sounding fun, then get the est80. Both complement each other imo. https://preview.redd.it/owm3lxbb5pnf1.png?width=1440&format=png&auto=webp&s=5c95c97cfc8551a53dbba6357ae5fc5af8f0e5d1

Aside from the archangel and est80, I also have the ruviest prelude, soundrhyme dte900 and sr8. Dte900 - midbass centric, thick lush & occasionally recessed vocals, very bright and energetic (borderline shouty/spicy) treble. It's a guilty pleasure set. A masochistic V shape set. Sr8 - more midbass centric than dte900 and has the fastest bass I've heard due to it being an all BA set. Vocals are forward, thick and lush just like the ISN EST80. Treble is bright and energetic and also shouty/spicy but not as bad as the dte900, slightly more tolerable lol. Either an U or W shaped set. Prelude - 2nd bassiest set overall, behind the penon archangel. Thick and lush mids but it ain't forward and is instead balanced, kinda a bummer but whatever. Treble is relaxed for the most part but can get peaky in the airy region at times. An U shaped set with an emphasis on subbass. Personal ranking in terms of musicality and versatility: 1. Archangel 2. Sr8 3. Isn est80 4. Dte900 5. Ruviest prelude

I know 5 Iems that are better and warmer and better bass and more musical !

QoA Adonis new … ISN NEO 3 .. ISN NEO 5 .. ISN H40 (the warmest) dark way more bass way more musical ! H40 is the widest sound stage in the line up . And my fav at the moment ISN EST80 . My preference is warm , bass , musical . I don’t care for details or clarity . Also you can make any IEM more warmer and more musical just by getting the CAYIN RU6 Dac . I can name more warm sets I have also but ones I named here are not expensive compared to my other warmer sets . But these I named are in my all time fav iems ! I don’t care for treble , details , clarity . So my whole collection is musical warm . Also a real cheap one is ISN H20 ! Maybe start with the H20 .

But what I named are better and Warmer, more musical and will eat Explorer for breakfast . Especially ISN H40 . All I have is warm , musical , Organic , vintage bass, textured thick Mids , Emotional Vocals ,Dynamic Vocals, Deep Bass , Basehead .

Ooh u got the Quattro !!! I’m glad I told you how good it was !!!! Great minds think alike ! We like the same sound signatures ! And you’re totally right ! All that other garbage don’t even sound good ! It’s boring and plain all of it is ! Shit is overrated ! Hyped and isn’t great at all ! If it doesn’t sound like Penon or ISN . All pass ! My other fav is Globe and Dome ! I just ordered EST80 also !!

Did u see the graph for EST80 ??? It looks really good . Diff from my EST50 ! The EST50 is like Neo 5s big brother ! Thick and musical . Vocals are soft Airy with that sparkle ! It’s crazy !

Yea the EST80 has 2DDS instead of one and 2more BAs then the EST50 . So the EST80 has prolly better sound . When I get it all hit you . It said 7 day pre order then it takes like 10-14 days to get to me !
