Hello, new user here. I just ordered the M9's, they should arrive next week. I'm pretty excited to hear them. I'm somewhat of a novice in the audio community(not a total beginner), the M9's will only be my 2nd high end IEM's, currently I have the Thieaudio Monarch's and while I like them a lot, I don't love. I'm just wondering if anyone here can compare the M9's to the OG Monarch's? I've looked around here and other places online but haven't found any real comparison.
First of all, the is one important thing about the IER-M9. Its is an closed/isolating IEM that doesn't allow for any sort of air pressure compensation.
That means they are extremely picky about what tip size you use and also how you insert them. A lot of people (i feel like more than 50%) have issues and can not fit them unless they use (Memory) Foam earpieces (Due to their nature, they let through air and allow for pressure compensation).
Sony released their own Foam (Proprietary Polyurethane Silicone mix) earpieces which, that is the current result of research in this forum, perform the best and seem to sound as close as it is possible to normal silicone if not identical (But they are hellish expensive. Normal foam cost 1-2€ a pair, the Sony ones (EP-NI1000) cost 20€ a pair but seem to last >1year rather than >1month)
So there is quite a possibility that until you buy a pair of foam, you'll not know how the IER-M9 actually sounds.
But if you manage to fit them properly with silicone or decide to get for foam, the IER-M9 sound much more "realistic" and "authentic". Instruments keep more of their natural character, everything sounds more "as it is there" and especially more fun.
Japanese divide the Tunings into three Categories
- Monitoring (Extremely Flat and not meant to listen at music but for mixing/mastering)
- Listening (A tuning that is designed to listen to finished/recorded music and should give an authentic recreation of the live performance)
- Club (A tuning that is mainly focused on Fun and works best with electronic music)
The IER-M9, even though it is an Monitor, belongs into the "Listening" category, it intends to make the music sound as realistic and live as possible but with a monitoring touch. So it sounds a bit less "fun" than most Listening Earphone and a bit more balanced overall, but still a _lot_ more fun than pretty much all In-Ear that belong into the Monitoring category.
So you could say a Listening Tuning that is more on the balanced side.
The Monarch is (my personal opinion) an typical ChiFi In-Ear with an Tuning that doesn't really belong in any category and its main target is to make the perceived amount of details as large as possible. It tries to sound fun, but also bright and detailed and all at the same time. So its neither Monitoring (It can't be used for that), nor is it really Listening.
Its a Monitoring Tuning with boosted bass and boosted treble. So it sounds like it does have more details, but actually the treble is less controlled and the actual amount of details is lower than with the IER-M9.
I personally dislike the Monarch (Mk2 too). I think their tuning is really weird and makes most music just sound off/wrong and unnatural. If you have a warm recording, it doesn't sound warm. If you have a cold recording, the treble is hot and painful. Even though the bass is boosted, most Instruments that need a good Bass like Cello or Double Bass sound flat and boring. Thats pretty much typical ChiFi (i can already feel how the crapstorm is incoming
).
Because i don't like them, nothing of what i said might be relevant for you^^
Even though i am not a big fan of Graphs because they only show a small part of the picture, these graphs make a pretty good job to explain the difference in tuning (unrelated to their sound characteristic which is very different too)
