Symphonium Meteor
I have been having the Symphonium Meteor on loan the last few weeks, the little red Meteor.
This is a 4 BA (Balanced Armature) IEM, costing $599.
This will not be a review, more like a small impression. Also going to compare it to one of my favorite IEMs, the AüR Audio Neon Pro am 10 BA set with a slight U shaped sound signature. I am not trying to offend anyone with this, this is a set I have been hyped to buy.
Disclaimer:
This is also a very subjective hobby where everything from experience, anatomy or age will affect what we hear. Also keep in mind that it is easy to use bold words when talking about differences, while it may be perceived as a small change for you. While I can perceive something as natural sounding, I do believe we can never get a perfect performance similar to what is achieved live.

Meteor sound impression
Most of my listening has been done with the Cayin N7 DAP, I have also used my desktop setup with Topping E70 + A90 Discrete. Tips have been Kbear 07 and Spinfit.
Must admit I had a hard time with the shell and finding a good seal, they are really small in the body and the nozzle has a different angle than the rest of my IEMs. There is also no vent on the IEM, I have never had problems before this set with pressure buildup. With lots of tip rolling and some advice, I found the Spinfit model I have to provide the seal. Also cable rolled to a better cable, the stock is okay sounding. But it doesn't sit well and makes Meteor being pushed out of the ear.
The meteor is described like this:
PHYSICALLY SMALL, SONICALLY LARGE
The Meteor, simply put - sounds MASSIVE. We created the Meteor to shock you the very first second the music starts playing - extracting the speed, detail and raw energy from your music and delivering it in a fun way that keeps you on the edge of your seat. Bass so physical that you feel air pushed into your ears and basslines vibrating from the thick bass strings. Treble so extended with its cymbals sounding ethereal and textured
The Meteor’s “U-shaped” sound signature puts its bass and high treble in the spotlight, yet maintaining a sophisticated balance to form a coherent and exciting experience so that you will spend hours listening in pure fun. All this in a compact form factor well suited for music listeners with smaller ears.
Give it a go - you will not want to miss this.
For me this description is not totally correct, the mids are very recessed. And make the sound more like an extreme V shape, bass is very present and also the upper treble. They say that the bass and upper treble is in focus and that is true, when listening to cymbals as they explain it has a good sparkle.
Overall the sound is soft and veiled, with full low end. As the bass is strong and full it is wrong saying it's thin, but the mids is thin and lacks presence.
Bass is big and soft, it's not the more visceral style that most DDs have and especially the fast DDs. It digs deep and can please most bass bass lovers, for me it sounds too soft and lacks impact. This is the same type of BA bass that many have complained of is not sounding like a dynamic driver, if you're not used to better BA bass this will probably sound good. Also using the set for a long time to get your ears adjusted makes it sound better and better, but then swapping over to a good DD makes it very obvious.
Mids is veiled for me, both instruments and vocals seem way too often like it's playing behind a carpet dampening the sound. While they sound okay, it's too distant and has not enough detail going on. I use Piano music very often to listen to how realistic it sounds, especially since I am used to hearing piano in my house from both my wife playing and myself. It is hollow on most ranges of the piano, and lacks a good realistic timbre.
Strings lack detail and fullness, going to brass instruments like Sax it is hollow and lacks detail. Good thing is that aggressive trumpet playing is tamed and less piercing, same for other instruments.
Male vocals are better than female, no doubt. Male vocals sound okay on most artists just a little thick, just a few that get more nasal sounding. Almost all females lack presence, and appear quite veiled.
Treble is better than the mids, and has some good detail and treble. Not on every song out there, depends how much of the detail is in the lower treble or upper treble. The cymbal hits on drums has a nice shimmer and has that extra making it sound more real, same for other percussion instruments. I also listen to much electronica where there are sometimes electronic sounds in the upper treble. I can then hear that Meteor has very good extension up top, almost too much where some tracks get very fatigued.
Soundstage is okay, more like a studio than an avenue in size. Would call it average in depth and width, it's also very circular. Imaging is very spot on.
Meteor vs Neon pro
First off this is not to trash Meteor, I wanted to try Meteor as I have heard so much praise. I love my Neon Pro and have it as a reference IEM, hoping for Meteor to be good as I love the design and wanted another all BA IEM. Using Neon Pro with switch ON as it makes the low end very similar in amount, the mids get then impacted slightly on some vocals.
Neon Pro is also not vented but the shell is larger so I never get any pressure build-up.
I will keep it short on this part, as it's in a different league and is not fair.
Bass is faster, more visceral. Not soft and actually sound close to a DD, resolution is high level above. Especially when listening to double bass playing with lots of resonances going on in the bass range. Drum kicks are as it should, not soft thuds like on Meteor.
Mids is leagues above, crystal clear sound on NP. Male vocals similar to Meteor is a little thicker sounding due to bass, but is more present and clear with more detail. Females have much more presence and are not veiled, even with the tuning switch on and gets even better with it off.
All instruments have more resolution, piano sounds real and true to life. Drums have a better impact and are actually present in the music. String and wind instruments, doesn't matter what instrument its clear and forward.
Treble is also super detailed with NP, even with the boosted upper air spike on Meteor the Neon Pro has more realistic air and shimmer. Super clear treble on acoustic and electronic music, and don't have that same fatiguing tendency.
Soundstage is very personal, Neon Pro has almost the largest stage and separation I have tried. Wider and deeper than Meteor, imaging also spot on perfect.
Conclusion
This is not the set for me, that is quite clear. I almost wish there was something wrong with the Meteor, I also got my wife with her petite ears to try it. She did say they were cute and small with nice ergonomics, but at first listen she also said the same, it was veiled and almost no detail in the music.
Had to ask a friend who also has many IEMs, and full BA sets. He demoed the Meteor at Zeppelin, first words this is totally not worth it. Unnatural, veiled and like listening from another room instead of in front of speakers
I am not sure what to say really, I have big problems understanding the $600 price. I have liked many BA sets before this (Bravery, SA6, RSV and Neon Pro).
Maybe it's good for intense music to relax it down, or this is just a tuning type some like.
Well tuned
