Sonny. CIEMs are cool and we love them here at Inearspace and it just so happens that a lot of people are clearly feeling the same way as us because new companies are popping up more frequently than ever, trying their hand at the art. Jomo are one of the newer folks on the scene. Hailing from Singapore the company is the brain child of Joseph Mou, I am sure you can now work out the name origins, and have a line up of both universal and custom fit versions of their line up. He has quite a background in DIY CIEMs like Dr John Moutlon has before he started Heir/Noble. When it comes to CIEMs as you know Josh and myself go back and forth on who’s gets the samples and Jomo fell in Josh’s lap and he sent off his impressions for a product which at the time was not yet released, a 6 driver flagship. This is where things take a turn to the ever so slight confusing because while Josh did get a 6 driver model from Jomo, it turned out to not be the flagship as oddly his ears were too small for the flagship 6 driver. Now I say oddly not because Josh has big ears, they are the tiniest things I have ever seen, thats canal size as well, but more because there is a universal fit version of the model he couldn’t get. If they can fit the 6 drivers in a universal shell surely his ears could manage, or he could have just had a universal…. never mind. Josh will chime in throughout this review with everything about the 6 as well as some other paragraphs!

Now I also need to quickly clarify the situation regarding the models, because Jomo have two 6 drivers in their range, the Jomo 6 and the Jomo 6R. It was the 6 that Josh received although it was hoped we would also try the 6R, so with my normal sized ears compared to Josh’s minuscule things, we decided I would then try the 6R. But what’s the difference? They both have 6 drivers right? Why the two models? Well it is not unheard of for a CIEM company to have more than one model with the same amount of drivers, think JH Audio’s Layla and Roxanne (both 12) or Vision Ears VE6 X1 and X2. In fact the comparison to the Layla and Roxanne is a very applicable one to this situation with those also sharing a driver count but featuring a complete different tuning and driver set up, hence the 6 drivers of the Jomo 6 can fit Josh’s ear but the different drivers and crossover components of the 6R could not. Funnily enough they also seem to share a signature goal with the two JH ladies although I don’t think this was in any way done in an attempt to copycat. Like the more expensive Siren, the Layla, the more expensive Jomo is the 6R with the R standing for reference. The standard 6 features a meatier sound like the Roxanne does next to Layla. Here is the description of the two from Joseph himself.

The Jomo6 follow the existing line of Jomo Audio custom IEMs and it is a one level up of the Jomo5. The Jomo6R is a reference model that has its own sound signature and different from the rest of the models we have. 

We think the Jomo6 can be a good pick for people like to enjoy pop music and those main stream songs for everyday listing. Very smooth on the high and mid and also gives punchy and fast bass. 

And the Jomo6R is more for people who are picky on sound. It has a very flat sound and gives a lot of detail. 

The two brothers share the same number of drivers but with a totally different tuning structure. And there is also a price difference. The Jomo6R starts from SGD $1,399 which is about $995 USD. The Singapore dollar is bit weak against USD recently. The Jomo 6 is SGD $1099, about $750 USD

It seems the 6 follows the house sound of Jomo while the 6R is their take on absolute reference, a claim that I take very seriously as you will know from my Rhines Stage 7 Review. The prices are $100 more if you want the Jomo design package included, we would heartily recommend that personally.

Accessories with Josh

Josh. The Benchmark for accessories bundled with a CIEM has been well and truly set high by the VE6. I know the product itself is much more expensive, but the accessories were just out of this world and its not something that costs a hundred pounds extra is it?! That product came with everything from a shirt clip to moisture pads to car stickers. It was genuinely outstanding. The Jomo “flagship” range lives at the opposite end of the spectrum, even below Harschacoustics. For your considerable outlay, you get a generic, cheap, plastic Otterbox fake (dolfin) with a Jomo sticker on it as well as an equally unimpressive plastic warranty card. You do get a little cleaning tool though… great!

Other big names like JH, UE, Lear, ACS are all doing things a little ‘beyond expectation and I really don’t understand why these smaller companies trying to break into the market aren’t at least trying to make it more of a luxury item. A flagship custom is a statement of what you can do as a company, why would you make it such a basic and cheap overall first impression?

Hey Good Looking 

S. Like we tend do a lot of the time now, me and Josh decided to let Jomo handle the design, especially as it’s their $100 SGD option. Both are truly stunning, I must say I do prefer how mine turned out by some margin but maybe there is some ownership bias there. I will add that for my pair I requested some sort of variation of the clockwork design but nothing specific in terms of colours. Josh has a mother of pearl faceplate that sparkles lovely on a smoky shell and mine are just a work of art, steam punk clockwork pieces over a carbon fibre faceplate on one channel, wood on the other. They match just lovely with the slightly glittering purple shells.

Along with the great design they do indeed seem impeccably built, no bubbles, no rough patches with only the model no. and my name on the unit being in a slightly blurry typeface giving me the only reason to whine. The cable is very much your standard CIEM stock like we have seen many times before and still hasn’t caused a problem.

Also interestingly they have opted to go for a horn like bore, as we have seen previously with the Vision Ears VE6 XC and Rhines Stage 7. Joseph goes over the reasoning behind this design.

All the Jomo series IEMs use the horn output. On one hand it will reduce the high freq attenuation like horn tweeter in the PA system speakers. On the other hand, the edge at the output will be much smoother than with the tube end at the output. I have seen some other IEM with the normal tube end at the output edge, after been used for some time, the acrylic covered on the soft tube start to crack and this may hurt the user’s ear canal.

For me comfort is OK but I do feel like the big horn bores can be quite obviously felt in my ear. Maybe they are a touch wide of the angle is not perfect but it is not bad or painful and seal is great. They are a tighter fitting CIEM. Josh seemed a lot more positive than me in this regard I must say, the next couple of paragraphs are from him…

J. I am pleased to tell you that these are one of the best fitting customs I have owned. They aren’t too deep or too shallow, they are just right for optimal comfort. The same goes for how tight they are really, I actually world prefer a little tighter seal but realistically they are very comfortable and very well fitted.

If I open my mouth wide I do lose seal but then again I only have one custom that doesn’t and that’s the UERM which is very deep fitting and pretty tight too, not to mention that it was taken with open mouth impressions by request of UE.
