You're right..... 7550/EX800ST is not high-end, pleasing-sounding (maybe some do find it "pleasing" if your come from and use hardcore monitor IEM like the Etymotic ER4) IEM's.
7550/EX800ST is a workhorse, industrial-grade, pro-monitor-class iem.
Sony Music, a special Sony division that makes/tunes 7550/EX800ST and their 20+ year old classic CD900ST makes no apologies for what it is. Because of what it is, it not NOT sold to the general public. Only those (like me) who seek professional "monitor" signature like this IEM and its headphone cousin CD900ST would be crazy enough to buy it. Plain white box packaging should be enough to repel the casuals.
The faithful reproduction of the sound you hear in the studio
While earbud that promises a light performance artists, the large-diameter 16mm dynamic driver unit, and achieve a natural frequency characteristics of the monitor speakers just like the recording studio. Resolution is excellent and I am suitable for monitoring.
Durability and wearability suitable for live
I adopt a flexible ear hanger that can adjust the shape to fit the shape of the ear. Definite wearability is obtained.
In addition, to achieve high input resistance of up to 500mW, and easy code conversion of the accident at the time, the functionality of the durability that is suitable for live environment.
The input to fully develop know-how of studio monitor headphones
As with any monitor headphone MDR-CD900ST has gained high evaluation in the field of recording, Sony Music Studios and Sony jointly developed.
Strict quality adjustment by sophisticated hand, I am less finish the individual differences of acoustic characteristics.
for what is worth i found overall stage on this Sonys being just Ok but depth of stage was fairly shallow, stereo dimensionality sometimes is blown so images really travel left and right instead of creating one solid image.
bass is perhaps best thing on this IEM but even here i could not stop thinking that this all about bass for the most. bass is fairly tight, well extended and good decay... but then happens a problem, mid bass overpowers mids eating fine detail and thinning overall mids, upper mids are so so and feel congested. i get a feel that bass runs in front of everything and the whole stage goes upside-down. another issue overpowering bass and mid bass do is shrink black space, all instruments are pulled closer together while singer voice moves back behind some of them. guitar reefs lack solid ramble and body and sometimes sound more like violins. but the biggest disappoint for me was thin air and wrong instrument placement on some materials, really the whole tuning is more or less bass, else things are really often missing, stage was not accurate or believable, black space is mostly grey and upper mids and trebles are grainy. and sorry but trebles are not really trebles on this IEM
i really wanted to love this IEM which i received for audition from a fellow HeadFier and i swapped several players i have starting with Cowon s9 and going to Colorfly C3 amped and then RWAK. sadly MDR-7550 came as disappointment on me no matter how hard i tried to convince myself.
Sadly so because it looks nice for the price but it did not cut for me sound wise.
If I remember, that's suppose to be the characteristics of most workhorse monitor-grade headphones (and now IEM's). You know that they have less treble and a smaller stage since they are monitor earphones. That's how pro monitor earphones are tuned. You can't use them for long periods with a brighter, possibly fatiguing, treble presence (see 7550's close cousin... EX1000). You want some off the treble presence for the mids to be more of the focus as well.

What could be "good clarity" and "sparkle" in a brief listening session could be "fatiguing" in the long run for the guys monitoring live sound (in studio, for example). Looks like Sony Music got the long session + fatigue part solved for this new IEM... just like the 20+ yr old classic CD900ST.
The above is one of the reasons I traded my TF10 for a 7550... one that actually has mids (relative to TF10) and deeper, but lean (and just-as-clean as TF10) bass
The fact that EX800ST/7550 IEM even sits alongside with the 20+ yr old CD900ST means it will be around... for a long time.
Sony Music figured something right by producing this IEM... and this special division don't just produce new headphones/earphones just for the heck of it.
