Pros: Great SQ, Sound stage, Case, Customer Service, Refit, Driveablitiy... more
Cons: Some air bubbles in ciem
I wonder why UERM is often disregarded while picking from $1000 range. I'm guessing that it's due to "only" having 3 drivers, versus having 8 drivers per side. I can say with confidence that driver number does not equal sound quality. Another reason I see why UERM might not be picked is its sound sig. It's perfectly flat. Personally, I love this.
Here is my break down: UERM is almost totally flat.
Sub-bass: Very very good. Great extension and presence.
Mid-bass: Flat. This is the part that people like emphasis on, but there is no emphasis. It's present and punchy imo.
Lower-mid: I don't listen to many musics with lower mids, but they have good clarity and detail.
Upper-mid: Very clean, detailed, emotional.
Lower treble: It can be little harsh, but not as harsh as SRH940. It's not rolled off, and is clean, airy, and detailed.
Upper treble: Superb extension with sense of air and detail.
Clarity: Best I've heard yet.
Detail: Best I've heard.
Sound stage: As a iem, it is the best I've heard, but obviously, they don't stand against full size.
Customer Service: As soon as my impression arrived, they emailed me with all the infos. I asked them many questions, and they were all answered. They gave me a completion date, and that date was kept.
Refit: My right side didn't fit, so I sent it off for a refit. They didn't even need a new impression. I described what part didn't fit, and they fixed it. They even upgraded shipping back to 2 day air for free. Very satisfied.
Packaging: I love the case. It's so much smarter than Westone Case I bought. It'd be nice if it was air tight though.
Cable: Cable is good. It's bit thicker than normal custom cables, but is still thin and very supple.
My story: UERM wasn't even on my list when I was first planning to buy a CIEM. During a short visit I had in HK, I visited Jaben and demoed many CIEMs. I tried JH13, JH16, Fitear Universals, Westone ES5, but I didn't like any of them. Fitears were too expensive and bit too bassy while JH13 didn't have mids that I was looking for. From there, I was about to purchase a Miracle, but I was unsure because people told me about recessed mids. Therefore, I looked at where I haven't. I disregarded UERM because it had 3 drivers, but still pulled a trigger on it. Now, I am very happy about it.
Please ask any questions if you have any.
Sibilance: It it less sibilant than SE535 and SRH940, but it is still present. I don't mind it so much, but it's worth nothing.
I sold my SE535 and X20 because UERM is just much better. SE535 sounded muddy, and X20 was too similar to UERM in tonal balance. Buying a Leckerton UHA6 amp.
UERM actually does a better job at placement than SRH940. UERM also benefits from a good setup.
Leckerton UHA-6S.MKII is good with UERM. One comment on bass. It is mid bass light, but most definitely not sub bass light. There is very good amount of sub bass.
