The list is sorted based on price, starting from the lowest to the most expensive. This is an ever evolving list. There are so many good sounding CIEMs out there that we can’t list them all, but here are our favorites for now.
Lear LCM Turbo
I know I know, there are many CIEMs in our list already. But after hearing its performance for this little price, I had to ask Lieven to put this one to the recommended list. I repeat, this is the cheapest Custom IEM as far as I know and for a base price of 220$, you get a very good customer service, great natural sound with excellent bass response with perfect sound stage for the money. I’m not sure you can ask more in today’s market at this level. Tatco has made a perfect job nailing this one. If you don’t like darker and thicker sounding IEMs than this is not your cup of tea; but if you like smooth, organic, natural and easy to listen to IEMs with a strong bass, then this is your budget CIEM without a doubt. I’m looking forward to work together with LEAR for future reviews and especially the exciting BAMDAS 5 model, which will amazingly have 5 dynamic drivers in it.
Jomo Audio Haka
As usual from Jomo Audio, you can expect a great build quality and top comfort. The Jomo Haka is easy to drive and pair with a whole series of sources and it delivers a really nice sound with a focus on musicality and naturalism. Jomo calls it a coherent and pure sound, and it’s exactly that. The Haka is affordable and it’s the perfect monitor to enjoy your music with. The Haka has an easy to like sound signature and it lets you dream away with your favorite tunes. For a one driver, you’re getting a lot in return and it is a recommended monitor in its price class.
CustomArt FIBAE 3
So far I have liked every single monitor Piotr has created and it’s no different this time. The FIBAE 3 is a step up from the two-driver version in all possible ways. The FIBAE 3 delivers a very impressive, top quality sound and the extension, naturalness and spaciousness it shows from only three balanced armatures is impressive. Looking at our recommended CIEM list, I just have to replace the twin-driver with this new version, as it to me is remarkably better when it comes to technicalities and naturalness. FIBAE 2 is still excellent but the FIBAE 3 just is even better
Cosmic Ears CE6
Cosmic Ears is to blame for my CIEM addiction. Cosmic is the Fiio of the CIEM world and I mean that in best possible way as the UK build/Swedish designed CIEM company, delivers THE best value for money on the market. The 6-driver CE6 (what’s in a name) is a very good all-rounder and it’s strength is in the fact that it does everything really good and with the same ease. It doesn’t really excel in voices or treble or bass, but the complete picture simply is one of the best. The way CE manages to make bass, mids and treble sound as one coherent “part” is one of the best in the market. If you’re in to bass there also is a B-version available that will rock your world.
Lime Ears Model X
In my opinion Lime Ears is one of the most overlooked brands in this field. They don’t launch many products every year like others, but when they get one out in the wild, it is a killer product. Aether was one like that two years back and Model X is one right now. It definitely is the monitor to beat in the sub 1000$ category and does also rival some higher tiers. For me it has become my reference below 1500$ and one model I certainly don’t want to part with – ever!
It is refreshing to see so much quality audio at a still affordable price, even though 900€ still is a tough pill to swallow for many, this price bracket has weirdly become mid-fi now. Lime Ears proves the contrary can be the truth and provides a CIEM with exceptional price performance ratio! X has become one of my easy-recommendations for everyone looking for a custom monitor in the sub 1000$ region or that does it all and that can adapt to your preferences.
Ultimate Ears Pro Reference Remastered
Nathan insists that this CIEM is included in the CIEM buyer’s guide as it is number one monitor. If I were to rethink my custom lineup in terms of preference, I’d have a hard time not putting the UERR first. It’s its flat, unaccented voicing and wide image that really does it for the music I most often put through my DAPs. For the daily grind, and for longer, more varied listening, the UERR is intensely satisfying.
Are you searching for a sound that is exactly like your studio monitors in a custom in ear? Look no further, this is one of your answers in this industry. You can add a little more color into the mix with a nice copper cable as well. This is not a monitor for those who seek a luscious sound with a big bass and vivid mids. You have to have the experience and ear training to appreciate what this monitor marvelously puts on the table. In my audiophile journey, the IEMs that caused me a “wow” are no more than fingers of one hand. Well, this one has already managed to be on my very special list of very special IEMs, and that should tell something.
The performance Warbler brought to the market is incredible. You may or not like its typical signature with more forward voices but it’s tonality, detail, speed and precision are exemplary and Warbler certainly sets the bar very high for the competition and who knows for their own multiple driver customs down the line if they do decide to go there. The Warbler Prelude is easy to pair and I basically liked it with every single amp or DAP I tried it with, you’ll just hear the characteristics of your source appear in the sound, but isn’t that exactly what we want? If you then realize they all doing it with one single BA driver, you can call it a small miracle.
CustomArt Harmony 8.2
The Harmony 8.2 is the successor of their excellent H8P. The new eight driver ciem – I fully recommend going for silicone – is wonderfully constructed and sounds detailed, clean and clear. It has a little more body compared tot he original with softer treble and overall this “update” scores better. The 8.2 is the perfect marriage between an analytic monitor and a musical sounding one. A TOTL monitor that can’t be missing from this list.
Lime Ears Aether
The Aether was the first CIEM in my collection that had a switch to turn on/off sub bass. It won our best CIEM award back in 2015 but it today still is a CIEM to take into account when shortlisting monitors. Aether is nice, Aether seduces, Aether rocks, Aether does it all. Aether is the kind of monitor that makes all types of music sound good, it’s engaging, has great imaging and sounds musical. The bass switch basically gives you two different sounding sets of monitors and that’s a great added feature. The overall sound signature is on the warmer side of neutral with a slight focus on bass and key characteristics are detail, depth and layering. For a 5 driver, it is sublime.
Jomo Audio Quatre
The package Jomo’s customers get with the Quatre is very nice. The case seems indestructible and the Ares II cable is a more than welcome addition in my books. It’s great seeing manufacturers care so much about their customers. The interchangeable filter system of the Quatre makes it a very versatile product. Depending on your preference you can get a mildly V shaped, balanced sounding IEM, or you can tune up that bass to earthquake levels. Your choice. My only wish is for them to replace the current filters with Torx headed ones. Jomo has created a very competitive product for a price segment that is filled with products, but they proudly can take up any fight in there. I really enjoyed my time with the Quatre, as it the emotions really can grab you. My filter of choice would be the silver (Musical) one, as the added low end and boosted lower mids give it a higher enjoyment factor to just kick back and relax with your favourite tunes.
Jomo Audio Tango
The Tango is smooth and musical and with its bigger body and warmth it’s a musical and easy to like monitor. At the same time it performs really good in general and especially the bass, upper mids and layering in general are really impressive. If you’re looking for a good monitor to have a hell of a lot of fun with, then the Tango has to be on your short list. Well done.
Ultimate Ears 18+PRO
The new UE 18+PRO comes with the new True Tone drivers, the Linum SuperBax cable and a new IPX connector. On top of that it also sounds heavenly and it has like the best hard case ever. If you take into account the fact that it only has six drivers, than there’s no other choice than to put the UE18+PRO on our recommended CIEM list. Yes it’s that good and special, even for $1499.
Audio has made quite an impact on my listening experiences. The A12t has won me over with a few short sessions and has made it quick on my shortlist of top monitors. With its thunderous bass, smooth and emotional mids and the superb TIA extension the A12t convinces me on all fronts. Together with the high resolution, big sound stage and great transparency the A12t puts a wide smile on my face when listening to my favourite albums. I fully recommend the A12t to anyone who’s looking for a powerful and smooth monitor that excels on technicalities and can be hooked up to virtually any source with its linear impedance behaviour. It certainly sets the bar high for its competition to take the crown as CIEM of the year. Exciting times ahead.
Noble Audio Kaiser Encore
I can honestly say, the Encore is a masterfully crafted in ear monitor with outstanding clarity and detail, superior control and coherence and the most natural iem I know. An earphone that undoubtedly deserves to be positioned at the top of the line. The Kaiser Encore is a clear step up from the original Kaiser 10 and deserves to be called its evolution, as it has gained many new abilities while still retaining what made the K10 so special. These little gems are comparable to some very expensive high end floor standing speakers and share similarities with even the finest and most prestigious PAs I know.
Ultimate Ears LIVE
Ultimate Ears wanted to create the ultimate stage monitor for professional users and they have succeeded in doing exactly that. At the same time the LIVE is more than just a pro monitor as it has a sound signature in which many audiophiles will be able to find themselves. If you’re an audiophile and fan of full bodied sound and impactful bass, a smoother tonality and soft delivery than the LIVE will impress. The LIVE is also the perfect solution for those who use their monitors both at home, on the go and on stage: the LIVE simply can do it all. On top of all that the LIVE comes with an excellent new cable system with improved connectors that will last a very long time.
Vision Ears VE6 XC
The Cologne based German company knows how to build great monitors. Their build quality and eye for precision are exemplary, their sound to die for. Nathan is a big fan of their six driver with the X control: The separation of musical elements along an X, Y, and Z linear path, is wide. If the VE6 wasn’t plugged into your ears, you might imagine the sound coming from a large headphone. The biggest, and most lasting impression is one of dynamic contrast. Not dynamic as in constant change, but dynamic in terms of the lively rendering of both lows and highs, and the degree to which each offsets the other. The two dance back and forth on the edge of a knife. Attack and decay on both ends are fast and powerful. Balance between them is perfect, and so, too, is the distribution of weight.
The Westone ES80 is a perfectly tuned neutral monitor with great extension, richness, speed and separation. Its sound stage goes both wide and deep and there’s great layering. In fact, I love the tuning and performance so much that the Westone ES80 is going straight to my CIEM recommendation list. The neutral, yet excellent, ES80 has quickly become one of my favorite CIEMs, and it’s even pushing the UM Maestro V1 from the list. If you’re looking for a neutral monitor that has the best possible technicalities then this is it. I fully recommend this marvel to the pro users and the audiophiles that want precision, neutrality, richness and extension. You’ll love it.
Jomo Audio Flamenco
The Flamenco is Jomo Audio’s newest flagship monitor. It is replacing the Samba (still great) as Jomo’s recommended flagship CIEM. What an awesome sounding monitor the Flamenco is. The competition nowadays is fierce and several companies have really great sounding monitors but to me, Jomo Audio with the Flamenco, is clearly one of them. Joseph managed to create a truly high end, TOTL custom IEM, and it performs exactly how you expect a flagship to do. It’s the best unit Jomo Audio has created so far and it has quickly become one of my favorite monitors. Yes I still use and love the Samba, but this just tops it.
Empire Ears Legend X
Empire Ears went out to create something truly unique with their new line-ups. The hybrid X-line features a hand full of proprietary technologies. Dynamic drivers that were designed from scratch, purpose-specific tuned balanced armatures from renowned suppliers, a high-tech coating to ensure that these drivers work at their very best and a super-charged advanced synX crossover network to fine tune them to their optimum performance. The build quality of the Legend X is perfect, with top quality fit and comfort. The sound convinces and the supplied accessories are the icing on the cake. A reigning package all-in-all.
It has been a while since the genesis of the original EarWerkz Legend, but evolution doesn’t work fast, today we have reached the Legend’s culmination. The Empire Ears Legend X is a highly enjoyable, dynamic and resolving monitor that is capable of surpassing its competition. The Legend X sounds incredible out of most sources, yet deserves to be used with the best and rewards the listener with even better sound as it scales up very well. Give the Legend some additional power and you will be granted an even higher end listening experience.
Vision Ears VE8
The VE8 is Vision Ears latest development and it only just has been released. I without doubt can say this is one of the very best 8-driver monitors in my collection. The VE8 delivers a very balanced sound where bass, mids and treble have the same body and perfectly flows in to eachother. The VE8 strongest point are it’s clarity, precision and extension. Could this be the very best treble I’ve ever heard from a CIEM? While the VE8 is expensive it really is very good. If you don’t have the money budget for one I advise you not to listen to it, cause you’ll be hooked even after listening to half a song already.
Unique Melody Mason V3
What an exceptional custom monitor the Unique Melody Mason V3 is. My hopes were very high as I love the Maestro V1 and even gave the ME1 the 2017 award, but it’s safe to say the Mason V3 exceeded them all.
The Mason V3 plays well with all the sources I used it with and it certainly is one of the very best CIEMs on the market at this point. A top quality monitor with these high end qualities doesn’t come cheap, but what you get in return is one of the very best customs out there.
64 Audio A18t
The A18t is to me the most resolving and balanced sounding monitor out there, with the absolute best treble ever paired with the most impressive sound stage of all. Bass that goes deep and is dynamically liquid and realistic. Thick and life-like mids on top of that. Within 30 seconds you can change the signature of it from powerful bass to the richest treble by going from the M20 to the M15 module. These and many more reasons made the A18 Tzar go directly to my short-list for Custom In Ear Monitor of the year (2017)!
