Ultimate Ears Pro 18+

General Information

The original UE18-Pro has been around for many years and has become a benchmark and Industry Standard.

The new released UE18+ Pro by Ultimate Ears has been redesigned and redeveloped from the ground up.

Inside each custom earpiece you will find a proprietary 6 speaker system, which delivers the headroom needed for stage use while optimally reproducing the total pro audio frequency range. This allows to consistently and predictably reproduce more detail and clarity to the bass, mids, and highs. Passive crossover technology electrically separates sound frequencies, so you hear clear vocals and instruments in the mid range, defined high notes along with a powerful, visceral low end all without masking and distorting what could otherwise occur.

While holding true to the sonic characteristics of the original UE18-Pro, the sound signature is improved by extending the high frequencies by 3kHz, now up to 22kHz. Ultimate Ears Pro have added their proprietary True Tone drivers, a new precision crafted sound engine, and also re-tuned the crossover networks.

And of course, the UE 18+ Pro takes full advantage of the all-digital modeling and printing process.

In addition, four separate acoustically tuned sound channels allow to keep frequencies separate and balanced until they blend naturally in your ear.

Like all other custom UE In-ear-monitors, the UE 18-Pro is compatible with wireless transmission systems and portable media and audio devices.

Ultimate Ears 18+ Pro Gen 2 (universal fit) Review- Old is gold
Pros: Pleasing neutral/ reference style sound signature, build quality, comfort, high end and practical cable, good technical performance
Cons: Can sound boring and nondescript at the first listen until one starts listening to the details

I had the opportunity to listen to this lovely pair of IEMs courtesy of a dear friend of mine for an extended period. The UE TF10 was one of the first recommendations that I had received from this forum when I was out to buy an IEM back in 2012. While I had missed the boat on that one, I did buy and use the consumer grade UE 350 & 500. This UE18+ Pro was the second gen version and has a universal fit shell. I'm sure that this version is discontinued, but it was fun to take this thing through its paces.

I should probably mention that I have a significant preference to the classic rock, heavy metal and progressive rock genres and I hadn’t listened to songs from other genres with this IEM. I had tried out this IEM using two sources- local 16 & 24 bit lossless audio files on my Android phone + Lotoo PAW S2 and secondly, through a Lotoo PAW 6000.

Specifications
Drivers6 BA drivers (proprietary True Tone drivers)
Crossover4-way crossover
Frequency Response5 Hz to 40 KHz
Impedance37.5 Ohms @ 1 KHz
Sensitivity105 dB @ 1 Khz, 1 mW

Build Quality: The 3D printed shells were well made out of medical grade resin and had thin black colored Linum SuperBAX 4 wire removable cables that plugged into the 2 pin connectors of the shell that were supposed to be waterproof. The black faceplate was classy and discreet and there were no seams or mold joints in the shell. Apparently, the faceplates and cables could be customized while placing an order. It had felt like a top of the line product that it was.

Accessories: While I didn't have the original box for this one at hand, I think the retail package consisted of a very nice carrying case, pouch, cleaning tool and an assortment of tips.

Comfort: The semi custom contours fit my concha very well and I was comfortable with them right off the bat.

Isolation and cable microphonics: I had tried out the UE 18+ Pro with medium sized silicon tips which fit me well and were very comfortable. It isolated well and the since the cable was worn over the ear, microphonics were almost non existent.

Drivability: The UE 18+ Pro had an impedance of 37.5 Ohms and sensitivity of 105 dB and both of my sources were able to drive these easily.

Sound Quality: Right off the bat, the UE 18+ Pro sounded very balanced and coherent. There were no unusual dips or peaks in the sound signature since it was a relatively flat or neutral sound signature that was intended for live musicians to listen to at length without fatigue.
  • Bass: Natural, tight, relatively neutral, controlled and could extend low when required. No sub bass rumble unless called for. Mid bass frequencies were also in control.
  • Midrange: Clear, natural and a little bit forward to lend texture and thickness to instrument notes. Upper midrange felt linear. Vocals were slightly forward but were quite natural and balanced well.
  • Treble: Smooth and natural. Lower treble was a little warm and I think this made it quite smooth and non fatiguing. Great tonal clarity in the upper registers.
  • Technical Performance:
    • Soundstage: Average- not too wide and deep. Instruments did not feel too far apart nor were they too intimate. Not as wide as modern flagships.
    • Details and resolution: These were handled very well. Picking out details in the song and recording was easy and the IEMs were quite resolving. These IEMs were proficient in highlighting the flaws in lossy files and low res recordings.
    • Instrument separation: It was also very good. Differentiating instruments, vocals and layering was easy.
Verdict: A fine IEM that would be right at home on the stage with a capable musician. It's a great choice for a well heeled audio connoisseur that loves and appreciate near neutrality or reference sound. The game has moved on now, but the UE Pro 18+ still holds its own and is a compelling argument for a relatively neutral IEM.

Pros: beside the RR probably the most homogeneous and detailed IEM of UE
lots of headroom and very good dynamics and stage
doesn't really do anything wrong...
Cons: ...but it's also a little boring and unemotional.
The mids could be more energetic
desirable bass optimization: more sub | less upper bass
Rating: 8.9
Sound: 8.8

Intro
The UE 6 Pro and the UE RR really convinced me. Both in their very own, individual way. Now let's get to an IEM that basically does little or nothing wrong, but is, to be honest, a bit too boring for me. In addition, it has a small boost around 600 - 700 Hz, which I don't really find advantageous in terms of clarity and makes voices or the whole arrangement seem more spatially set back and flatter.

One thing you have to give Ultimate Ears credit for, they don't dazzle the consumer with their marketing by any praise and promises. Well, that they want to make their product stand out is clear and some exaggerations as well, but the whole thing has substance. But more about that in the sound analysis.

UE 18+ Pro was provided by R + R SonicDesign.

Handling
>> Identical to all tested models of Ultimate Ears <<

The UE 18+ Pro is basically a custom IEM, but can also be manufactured as a universal IEM. If you decide on the custom variant, you will receive an individually adapted in-ear based on a personal ear impression, which is also only "compatible" with your own ear canal.
With universal IEMs, there is no way around a silicone or foam attachment (which is of course included in the scope of delivery in this case), but this can influence the sound characteristics and the sound can be falsified both positively and negatively.
The scope of delivery consists of a cleaning tool for the sound tubes, a removable cable, which was especially developed for stage use and the IEM itself. All this is in a screwable, round and black metal case, or square folding case, where the respective name of the owner is engraved.

Ultimate Ears relies on a specially developed IPX connector in their products. This connector is not compatible with MMCX or other connectors. I personally find it better than the one I know so far. It's more compact, sits bombproof and is easier to detach than the MMCX. The tight closure of the two connections (male/female) prevents moisture or dust from entering the connection, which is very important for stage use.
The cable is available with or without ear-loop, clear or black, and with a length of 125 or 160cm. There is also a balanced version (4-pin 2.5mm mini-jack) and a Bluetooth cable incl. remote for telephoning and controlling the Smartphone / Player.

With a custom IEM you don't have to worry about the fit, comfort and isolation. No matter which acrobatic exercises you perform, the IEM will not move from the spot and will also isolate you almost completely from the outside world. If something does pinch, or an adjustment is necessary, you can have it done free of charge by the respective distributor, or directly by Ulitimate Ears.

The cleaning tool is not only practical, but also really necessary, because as with many universal IEMs by now, there is no protection (mostly by a metal grid) in the sound tube, so earwax and dirt can get into the in-ear more easily. For the careful user cleaning is certainly not a foreign word, but it should be mentioned nevertheless.

The design of the UE 18+ Pro is individually left to each user. What remains the same is the transparent 3D-printed housing with a view of the inner workings, but with the faceplate you can let off steam to your heart's content and the ear side is individually made to ear impression anyway.

Sound
Each in-ear of Ultimate Ears has its own characteristics, which are also crystallized by UE in the description. If the UE 6 Pro is recommended for drummers, or the RR as a reference and mixing tool, the UE 18+ Pro will give you more headroom and therefore better dynamics. This is indeed the case and is especially noticeable with more output power. Between quiet and loud passages there is a smooth dynamic range, even in common interaction, without any overlapping or loss of information.

Similar to the UE RR, the bass only jumps as high as it has to. It treats the sub range rather shabby, but has presence there as well, which makes the bass appear quite linear. It lacks a bit of punch and nuances, but stays clean. Nevertheless, I still miss a bit of tightness here. It has a bit more quantity than the UE RR, but in quality they don't take much away from each other. Also here typical BA, but I'm spoiled a bit by the UE 6 Pro. But the bass is much more stable and linear than many other in-ears reviewed so far, which used a BA driver and can be seen at about the same level as the BGVP DM7, which I also attest a very good BA bass.

The UE 18+ Pro sounds warmer than the RR due to the slight bass spur, especially in the upper bass.
Likewise, they are positioned a bit further to the middle of the head and not as much in front as for example the UE Pro 6. This is not a negative criterion, but in any case a change to which one has to get used to shortly, similar to the OH500. As technically skilled as the mids are, I lack a bit of energy and liveliness. That makes for a bit of tristesse. Maybe the best way I can explain it is this: When I'm on my own, I listen to music via in-ears in almost every situation. But that doesn't mean that I am completely in the music with my head all the time, but that I just let it run as background noise and let my thoughts wander. But now there are in-ears that manage to pick me up unexpectedly and focus my attention on them without me paying special attention to them and the music. With the UE 18+ Pro, I have to concentrate on it specifically, otherwise the music will just ripple away. Admittedly high quality, but somewhat emotionless.
Sometimes a peak creeps in at the mids, especially on electric guitars, where I'm a bit sensitive and they become slightly demanding, but that's a rare exception. I would describe it as slightly roaring. Basically, the mids of the UE 18+ Pro are very soft, relaxed and peak-free. Even sibilants are for the most part well avoided.

Trebles are relaxed and have a good extension, but they can't really assert themselves, or rather, the UE 18+ doesn't pay any special attention to them and puts more emphasis on safety. Once you have got used to the signature, the trebles are very harmonious and above all natural, without any artificial build-up. But they should have a bit more steam for my taste. In general, I'd like to see a bit more clarity in the whole signature, but that's grumbling at a high level. The trebles blend in very well and provide a homogeneous sound.

I repeat myself, but location, 3D display and positioning are clear strengths of the UE-IEMs, and of course one of the UE 18+ Pro. However, they tend to stand out more with more output. The RR is a bit more sensitive and convinces even with less power. Since the stage of the UE 18+ Pro is centered a bit more in the middle of the head, it may not seem very big at first, or separate, but that will come with time.

Outro
Very safe earphone for sensitive ears. The tuning doesn't quite suit me and is too unemotional for me. Well-behaved, but technically adept, describes the UE 18+ Pro quite well. It doesn't disguise anything, but doesn't catch your eye. That's quite pleasant at times, but not quite to my taste.
It leaves me a bit perplexed, as it basically does nothing wrong, but doesn't completely pick me up even after a long listening time, although I like it much better after a short warm-up phase and also lets me dive deeper into the music.
However, with its technical features and also the large headroom (even at high volume nothing seems compressed), it seems to me to be a very good tool for the stage and for perfectly tuning the personally preferred mix. Also for this reason I want to remain objective in my evaluation and can also argue the score with a very good conscience.

I wouldn't buy it, but when I get my hands on it, I could easily bend it into my preferred direction with one or two small adjustments in the equalizer.

Pros: Natural tone and timbre. Great resolution. Non-fatiguing.
Cons: Could have more sub-bass rumble. If more detail could be added without disrupting the accurate reproduction of tone and timbre, it would be great, but it's not a deal-killer.
This IEM is for those who love the sound of natural instruments and the human voice. I purchased these from Massdrop as the Universal Pro-To-Go version. These are the 2nd Gen of the UE 18+ Pros (discontinued).

Tonality and Resolution: 5/5
No other IEM I've listened to comes close to the mids reproduction of the 18+ Pros. Textures of male and female voices come across vividly, and instruments sound exactly as they should be. The True Tone drivers really make a difference in reproducing the signature harmonics of each instrument, so much so that I find it hard going back to other IEMs which sound sterile and artificial by comparison. Also, because of the smooth treble, I can listen to this IEM the longest - no fatigue whatsoever.

Separation: 4/5
Great imaging, and ability to hear all parts of an ensemble. That being said, the IEM is extremely coherent. Feels like sitting in the middle of an orchestra.

Detail: 3.5/5
You get micro-detail with this IEM, but not with the clarity of a more neutral-sounding IEM. This is NOT an IEM for analytical listening (unlike the InEar ProPhile-8), however - you'll forget you even wanted a higher level of detail listening to this IEM.

Soundstage: 3.5/5
This is in relation to the Campfire Andromeda. Not huge, more on the intimate side, but can range depending on the recording.

Driveability: 3/5
My standard source is the Pico Power and Dragonfly Red out of my Macbook Pro. These IEMs need to be amped to reach their full potential.

Bass: 3/5
Good texture, although there's a bit of sub-bass rolloff.

Mids: 5/5
The best of the best.

Treble: 4/5
I don't like sharp treble. While this doesn't sparkle like the Andromeda, it has enough definition to bring out the right timbre while never fatiguing my ears.

Conclusion:
The most natural sounding IEM I've ever heard. Jazz and classical lovers - this is it.
