Review: Jomo Audio Jomo5 & Jomo6R

Disclaimer: I was sent the Jomo Audio Jomo5 and Jomo6R free of charge for this review. This is the first time we work together with Jomo Audio. I only paid for getting my ear impressions done and for sending them all the way to Singapore.

Jomo Audio – Singapore

A few months ago I stumbled upon Jomo Audio on Instagram. After “liking” a few posts we got in touch by email and we quickly agreed on doing a review. The Jomo5 review is part of the 5-driver review series. So far we have looked at the Rhines Stage 5, the Cosmic Ears CE5, the Vision Ears VE5 and the Lime Aers Aether (Best CIEM of 2015). I’ll also be looking at the Jomo6R which is their TOTL monitor. Both monitors were custom built for me, these aren’t universal units.

I have to admit I had no idea who Jomo Audio was but I decided to go for it based just on pictures of their units. Even the world’s most known headphone forum doesn’t say a lot about Jomo Audio. George to the rescue!  He told me that Jomo is a very local brand that started with simple designs but Jomo grew quick in a short time, bringing several different models to the now international market with improved designs. I’ll get back to the design later but what an evolution they underwent.

Jomo Audio was founded in Singapore by a broadcast engineer who has first-hand experience to the video and audio content creation in studio, live mixing and post-production every day. The Jomo series IEMs were designed to recreate the exact form of music recorded in the studio. The founder (Joseph Mou, hence the JoMo brand name) was highly inspired by the Japanese craftsmanship and spent months on research and experimenting in order to deliver the finest IEM for musicians, worship groups and audiophiles. (cfr their Bio). Jomo Audio also does reshells for several different brands and sells Dryboxes (a must in humid climates) and Linum cables. They also seem to offer custom sleeves for your universals. Sure you’ll look weird using them but at least you’ll have a good fit and as a result, good sound.

Joseph is a very nice guy to deal with, it’s that simple. It’s funny but I seem to get along really well with all the Singaporeans I know. George with who I check a lot of ideas with – he’s kind of my to go to guy for advice – told me right from the beginning that the audio community in Singapore was rather fanatic and lots of our readers are actually based there. Another company I like is Effect audio where Suyang is always a pleasure to deal with. One day I will go to Singapore, one day.

Jomo5 & Jomo6R

The Jomo5 according to Joseph has five precision balanced armature drivers per side, specially tuned to deliver the most pleasant sound you have ever heard. The Jomo5 has a three ways passive crossover and covers the full spectrum from 20Hz to 20KHz as usual. The 5 Balanced Armature (BA) drivers are set up as following: Dual High, Dual Mid and Single Dedicate Woofer. The Jomo5 also features an advanced horn sound outlet design (more on this later), has an impedance of 25Ohm and a sensitivity of 125dB which is rather high.

When Joseph and I were talking about the Jomo5, he asked if I was also interested in reviewing something new. I figured it would be the Jomo8 but it in fact turned out to be the new Jomo6R where “R” stands for “Reference”. The Jomo6R for now is Joseph’s Top Of The Line monitor and it has six Balanced Armature Drivers per side. The Jomo6R is the first model of the R series which aim to have a flat response for reference monitoring. With 6 precision balanced armature drivers per side, the 6R according to Jomo Audio, delivers the most crisp sound and you will not miss any single note. The 6R comes in a single Dual High, Dual Single Mids and single Dual Vented Low configuration. Just like the Jomo5 it has a three-way passive crossover network and it uses the “advanced horn sound outlet design” as Joseph calls it. Sensitivity is 126dB and it of course also covers the 20Hz to 20KHz spectrum. The Jomo6R has a 20Ohm impedance.

          I put in my H8P yesterday before going to bed. The H8P has more focus on the treble and sounds harsher. The Maestro has more body in mids, bass and sub bass. Detail on both is excellent but the layering on the Maestro is a lot better. The H8P sounds fairly inside your head compared to the Maestro’s superb sound stage and “open-ness”. Both have great Left-right balance.

          Hope this helps!

            I cant help but wonder, when you say Maestro are you referring to the 6R? Because the question asked for comparison between the 6R and H8P, which I am also rather interested to know. Thanks!

    I was wondering, since you mentioned that Jomo does custom sleeves, if you have any experience with using them (sleeves). I’ve been on the fence about trying custom sleeves for my Shure 535s, and I was wondering how they effect the sound signature…I actually haven’t read too many reviews on custom sleeves, any input would be appreciated.

      To be honest, Anthony, I have never tried. A perfect fir would mean the best possible sound. I don’t think it will change your sound signature

      It will change the SQ as the distance of the tip of your IEM is usually further away than when compared to using it without the sleeve, plus there is the question of the tube in the custom sleeve itself. Like anything else, having another connector, for want of a better word, will also test the seal achieved. I had a pair made once and now it just sits there as an expensive pair of silicon blobs.

        Thanks George…That was my fear. Sleeves “sound” like a good idea in theory, but I figured if tips can change the s/q of earphones, then these should too. I’ve seen very little about them on line…thanks again.
