Westone ES80

Sound Analysis.

In the intro of my review I mentioned that ES80 made a big step toward audiophile oriented tuning.  Of course, it’s a subjective opinion since definition of “audiophile” sound is vague, with some considering it to be a more revealing analytical sound, while others leaning more toward a natural organic detailed sound.  I find ES80 to have a more neutral, revealing signature with a natural realistic tonality that focuses on mids.  It’s not a mid-centric or mid-forward tuned iems, but no matter what song/genre I’m playing, the first thing that captures my attention with ES80 is the powerful rendition of vocals.  Both the bass and the treble have a remarkable extension with an excellent quality, but their neutral quantity gives more room for vocals to shine.

In more details, ES80 bass extends far, down to a deep sub-bass which is accurate and has a distinct velvety rumble, but it’s more neutral in quantity, just slightly elevated.  Mid-bass is tight, fast, articulate, with an impact a bit north of neutral.  ES80 responded quite well when I applied the EQ to boost it, still retaining a good control and separation from lower mids.  But every time I tried experimenting with EQ (for some reason, lately I’ve been craving more bass), I went back to a flat EQ setting because I wanted to hear the original tuning which delivered a very realistic natural bass timbre.

Lower mids are also more neutral, perhaps taking away some of the Westone signature lushness, making the sound leaner to ensure there is not even a hint of veil.  Upper mids in ES80 do truly shine, being more revealing (in a natural way), more transparent, with a perception of being a little more upfront, including a nice layering and separation.  Treble is a little more relaxed, with a nice level of sparkle and airiness, but not too elevated or too airy, being smoother and more natural.  As I mentioned before, extension is excellent, and overall treble definition is very good and non-fatigue.

Despite having a smooth sparkle and well controlled airiness, the layering and separation of instruments and vocals is quite good.  And thanks to a very wide soundstage, which surprisingly holds its width even with some of my lo-fi sources, the positioning and imaging of instruments and vocals is very accurate and precise.  You can pin-point every sound easily.  With a soundstage, it’s not only the width but also the depth which I found to be impressive, putting you a few rows in front of the performance, not too much out of your head, but still enough to project the sound a little further.

In general, I think the neutral signature of the sound also contributes to the coherency of the tuning, with all drivers working in unison with a smooth transition from lows to mids and to highs.



Here is how ES80 compares to some of the other IEMs inside and outside of Westone family.  In every case I noted the volume setting which can give you an idea that with its average 111 dB Sensitivity and higher then average 80 ohm Impedance, you need to push the volume a little higher.  Of course, I made sure to volume match every pair.

ES80 (v71) vs W80 (v51) – ES has a little wider soundstage.  W sub-bass goes deeper, with more rumble, mid-bass has more impact, and overall bass is more lifted vs ES which has a more neutral bass, though still a great low end extension.  Lower mids are leaner and more neutral in ES while W has more body.  Upper mids more revealing, more transparent, and slightly dryer in ES while W upper-mids are a little warmer and more organic.  Treble has a similar sparkle with a nice definition and average airiness.  W sound sig is more balanced while ES is more neutral-natural/transparent.  If I would to summarize the main differences between these two, ES80 is more neutral, more revealing, more transparent, while W80 is more balanced, with a better low end rumble and mid-bass impact, and smoother and more organic tonality.  I had someone ask me if I consider ES80 to be an upgrade of W80.  I find ES80 to be a side-grade due to difference in tuning, where these two nicely complement each other.

ES80 (v71) vs ES60 (v51) – nearly the same soundstage expansion. 6 sub-bass has a little more rumble, and the same with mid-bass, just a little more impact, not a huge difference but noticeable enough to make 8 bass sound more neutral in comparison.  But the bass itself is tighter and more articulate with a little faster attack in 8.  Both have a relatively neutral lower mids, maybe with 6 having just a touch more body.  With upper mids, 8 is a little leaner, and with a little better layering, while 6 is a bit smoother and warmer, but not by a lot though.  Treble is very similar, and in both cases has a nice definition and well controlled sparkle.  While both are close to neutral sound, 6 is just a touch more organic with a little fuller body, while 8 is more neutral with a little better transparency.  It’s still a coin-toss for me which one I like better.

ES80 (v71) vs UMPro50 (v61) – Pro50 soundstage is noticeable narrower.  ES bass is more neutral while Pro50 has a deeper sub-bass and more mid-bass impact, but at the same time ES bass is faster, tighter, more controlled and doesn’t spill in lower mids like Pro50 does.  ES lower mids are more neutral and leaner while Pro50 has thicker lower mids which adds more body to the sound.  ES upper mids are more revealing, more detailed, brighter, leaner, while Pro50 is a lot smoother, warmer, pushed a little more back, and not as layered/separated.  ES has a little more sparkle in treble and more airiness.

ES80 (v71) vs UE18+ Pro (v73) – very similar soundstage expansion, with UE has just a little more depth. With bass, UE sub-bass has more rumble, while mid-bass has a similar quantity, maybe a touch less in ES.  Both have a tight, articulate, fast bass with an excellent control without spilling into lower mids.  Lower mids are also similar and sound very neutral.  Upper mids are transparent and layered in both, revealing and detailed, with the only difference of ES being a little smoother and a touch warmer while UE being brighter and a bit dryer.  Both have a treble with a good definition, but UE is crisper and a little brighter.  While these two have many similarities, the main difference is in upper mids/treble where ES sounds a little smoother and more organic, while UE is more revealing and brighter.

ES80 (v71) vs Pristine HUM (v52) – ES has a wider soundstage, while HUM goes a little deeper.  HUM bass has a little more sub-bass rumble and a touch more impact, but ES bass is tighter, more articulate, and better controlled.  Both have a neutral lean lower mids.  With upper mids, HUM is more forward, brighter, thinner, while ES is more natural, a little warmer, and with better layering and separation.  Treble is crisp and well defined in both, but HUM is grainier.  Here, the upper mids/treble advantage goes to ES with a more natural and transparent tonality.

ES80 (v71) vs Noble K10UA (v59) – ES has a wider staging while K10 has more depth.  K10 bass has a little more rumble and more mid-bass impact, while ES is more neutral in comparison.  Both have a tight and articulate well controlled bass.  Also, both have a neutral leaner lower mids.  Upper mids in K10 are brighter, leaner, and dryer, while ES is more neutral, slightly warmer, and more organic.  Treble is crisper in K10, though both are well defined.  Also, K10 has a little more airiness.  In this comparison, bass difference didn’t stand out as much, it was rather a brighter upper mids of K10 vs more organic smoother upper mids of ES.

ES80 (v71) vs Harmony8.2 (v61) – ES has a little wider soundstage, while H8.2 has more depth.  While sub-bass is similar, I hear H8.2 having more impact in mid-bass.  Both have a well controlled bass, but ES is a little tighter and faster. Lower mids are more neutral in ES while H8.2 has a little more body.  Upper mids have a similar presentation, but ES is a little smoother and a touch warmer, while H8.2 is a bit brighter and just a little thinner.  Treble is very similar, crisp and well defined, with a similar extension.

Westone Family (ES80, ES60, W80, UM Pro 50):



As I mentioned in Comparison section, due to an average Sensitivity and above average Impedance, you do need to push the volume higher when listening to ES80, but they don’t require higher power to sound great and can be easily driven by any hi-fi or lo-fi source.  Of course, you can’t expect the same level of resolution and transparency from a smartphone or an average laptop as you would from high end DAPs, but to my pleasant surprise it paired up good with all the sources.

Plenue 2 – wide/expanded soundstage.  Neutral revealing tonality, very transparent, layered, dynamic sound.

LPG – wide/expanded soundstage.  Neutral-balanced revealing tonality with more bass impact, very transparent, layered, dynamic sound.

DX200 w/amp2 – wide/expanded soundstage.  Neutral revealing tonality with a little more sub-bass rumble, very transparent, layered, dynamic sound.

X7ii – wide/expanded soundstage, a touch less width.  Neutral-balanced more organic tonality with a nice sub-bass rumble, great transparency, and good layering.

Opus#2 – wide/deep soundstage expansion.  Neutral-balanced revealing tonality with a little more bass impact, very transparent, layered, dynamic sound.

AK120ii – wide/expanded soundstage.  Neutral-balanced revealing tonality with a nice sub-bass rumble, very transparent, layered, dynamic sound.

M2s – wide/expanded soundstage, a touch less width.  Neutral-balanced more organic tonality with a nice sub-bass rumble, great transparency and layering.

N3 – wide/expanded soundstage.  Neutral-balanced revealing tonality with a nice sub-bass rumble and fast mid-bass punch, very transparent, layered, dynamic sound.

Note 4 – wide/expanded soundstage.  neutral-balanced revealing tonality with deeper rumble and more mid-bass impact, transparent, layered, dynamic sound – surprisingly good!



I mentioned in the Intro that I consider W60, W80, ES60, and ES80 to be current Westone flagships.  We are so used to new releases with higher driver count, that we automatically assume it to be the next flagship.  But we all have a different definition of what we consider to be a flagship, thus it’s just a label which can be applied to different IEMs from the same manufacturer.  Westone has a lot of fans (A) who can’t get enough of their house sound, craving that lush, laidback, organic, detailed, musically tuned tonality.  But there are also fans (B) who want to push the envelope of this sound tuning closer to a neutral-balanced signature, with a better retrieval of details and a more neutral tonality.  If you follow the sound signature changes from W60 -> W80 -> ES60 -> ES80, you can trace the evolution with a transformation from (A) to (B).

And when you arrive at the latest ES80 stop, you will be greeted with Westone interpretation of audiophile sound tuning with a more neutral, revealing signature and a natural transparent tonality.  Also, don’t be surprised to hear one of the widest soundstage expansions in Westone C/IEM line up.  But if you find yourself craving more bass and warmer tonality, you can go back to ES60 or W80 (if you want more slam).  And if you want more lushness, retrieve back to W60.  My point – you pick’n’choose your own flagship, with the only exception of ES being a Custom IEM which can hold back some people because they can’t audition these IEMs before the purchase.  In that case, hopefully my review will be able to guide you.

      1. Thank you very much! So you mean CIME is not suitable for pop? If I want to buy a CIME, which do you recommend(not a westone is alright)?


      2. You mean ciem, as in custom iem? Ciem or iem is just a shape of the shell which going to have a different fit in your ear. It has nothing to do with a style of music you are listening. I just suggested that you might want more bass in the signature of your iem. Es80 is neutral, while w80 will have more bass punch. You first need to choose iem based on its sound signature to fit your music preference, there are hundreds of iems, narrow it down to the price based on your budget. Then, when you narrow it down, see which one of these iems is offered in Ciem shell.


  1. Yes,I mean ciem. My budget is around 2000. I use Westone w4r now and I want to upgrade it. I know iem or ciem have nothing to do with the music I am lestening, but I just want to try a ciem. Which one do you recommend? Thank you!
