Best headphones I ever had. No need for noise cancellation with these ones.

BEST set of earphones I have tried 28 Nov. 2013
By Wayne - Published on Amazon.com
I lost my Monster Copper Turbine and had to get a replacement. Loved the Monster earbuds but I decided to redo my tests to include some of the newer earphones or ones which were said to be good but I have not tried.I tested the Westone W40, Shure SE535, Klipsch X11i and X10i, and Monster Copper Turbine before deciding on the UM Pro 30.

I have to say that the one that disappointed me the most was the SE535. At the price point, the clarity and bass were not exciting for me. Sound was very balanced but not excellent in each category. I wasn't moved by the sound that came out from it.

The Monster Copper Turbine was still very good at more than half the price I would have had to pay for the SE535. And the bass from these buds were amazing! Much better than the SE535. I would have been happy to purchase it again. Both the Klipsch X10i and X11i were similar as well. Bass is decent but not as strong as the Monster buds but clarity was up a notch. Very balanced set with a great fit on the standard buds that came with the set.

After I tried the W40, I thought it was great as well. Bass was improved and superior to the SE535, but somehow the music didn't move me that much more and I couldn't justify the price difference from my perspective compared to the Monster or Klipsch buds.

Eventually the one that got me was the UM Pro 30. Bass was strong but not sacrificing sound quality. Each note, beat and ring were crystal clear and the music was so balanced and perfect that I just had to get them on the spot. Fantastic piece of equipment. Now I could justify the price difference.

Only one problem. The UM Pro 30 does not come with a remote and volume control to work with a smartphone. However, they gave me a solution, which is to get the Shure smartphone cable. The plugs fit well and I now have absolutely no problem. I am a happy man!!!


I have since switched to the Westone W series MFI replacement cable and they work even better than the Shure ones. Found the Shure ones durable but thick and bulky, so they couldn't really fit into my usual earphone pouch. the We3stone MFI cable is thinner with no discernable difference in sound quality. Get them if you need a remote or to use them with the smart phone.

I use these weekly now on stage and really enjoy them. I've compared them with the $500 pair of W40s and the difference I can tell is the W40s have more mid and low tones which set the instruments apart more. However, for what I'm doing on guitar, and the fact that I can hear everyone very well, I don't plan on upgrading these until someone throws a stack of cash at me (what? it could happen.) The fit, the bag of ear pieces, cable, case, and quality are the same as more expensive ones, it's just the number of drivers/channels that differ.

They feel great in my ears and I'm not having any bad rubbing or hot spots. I'm giving it a 5 rating because although there are better ones out there, these are 100% what they advertise and are great for me.

After much research I decided to go with the UM pro 30's for their 3 armature crossover set up. These little bad boys are just awesome. Highs are crisp and have a presence but not overwhelming, Mids warm and filling, and the Lows just perfect not over powering the rest of the soundstage. Just got these and within the last hour of continuous play I have no regrets whatsoever. Comfortable and the perfect amount of sound isolation. Will post more after a few more weeks of use.

Amazing BA driver performance with "dynamic driver" bass quality! 11 Dec. 2014
By Twister - Published on Amazon.com
Arrived in a compact box, the outer sleeve of the package had a lot of useful info to start exploring the product even prior to opening it up. First of all, UM Pro is a Professional Musicians' IEM series which has a specific tuning aimed at monitoring of the music versus W-series being more for general consumer listening. To reflect that, UM Pro 30 cover had a picture of one of the performing artists. Looking around the back and sides you get a walkthrough of the design, tech specs, and accessories. Once the outer sleeve is off, you have a soft touch magnetic flip cover box which is almost identical to the one from W40. Premium touch material and "wow" factor when you open a cover flap adds us to a rewarding unboxing experience. Under the cover the first thing that jumps at you is an orange monitor vault storage case and set of clear UM Pro 30 (also comes in a smoke color) in a foam cutout display.

All the included accessories are placed inside of that storage monitor vault which resembles a pelican case. This vault is build like a tank and can probably withstand the most extreme abuse. With soft inner foam lining and air-pressure valve it can protect your IEMs in a carry luggage, or tossed in the travel bag, or thrown off the roof of 10-story building, though for everyday use it's a bit extreme and you might want to pick up a regular pocket friendly zipper case. Inside of the vault you will find all the included STAR and True-Fit eartips. You get 5 pairs of each type, all in different sizes and shapes, color coded so you don't drive yourself crazy pairing them up. Also, included a earwax removal tool - not for your ears but rather for a nozzle of UM Pro. This set of accessories is very similar to W40 with an exception of no extra cable with remote/mic. Makes sense because W-series is more consumer oriented with appeal to smartphone users, while UM Pro series focuses on pure music performance with included audio only cable. But due to removable nature of the cable and universal MMCX connector - you can always use your own upgraded cable.

Looking closely at the cable, you have 90 degree molded connector with a gold-plated plug. This design is convenient to use with any audio player or smartphone case. A braided cable with reinforced shielding is attached right to the molded plastic part of the connector, though there is no strain relief. I was a little bit disappointed about that, but at the same time braided nature of the cable helps to relief the strain naturally when wires are bent. Moving up to y-splitter with a chin-slider, it has a slick design and similar lack of strain relief. Also, I noticed a chin slider had a bit of friction due to a braided/twisted nature of the cable. The good news - this is a removable cable which takes a weight off your shoulders if anything happens. Going up to earpieces, you have a flexible memory shielding piece which I actually liked a lot. With a regular cable, like in W-series, you have to bend it over your ears and use chin slider to assist with keeping wires together. Other headphones use annoying memory wire that you have to constantly shape and adjust with every fitment of headphones. Here you have a pre-shaped slim shielding that goes right over your ears and doesn't need any adjustment. It's very convenient especially when you have to store your headphones in the case/vault and don't have to worry about preserving a memory wire shape.

The attachment to earpices has a universal mmcx connector which means you can replace cable if it breaks or if you want to upgrade it (like a popular choice of silver-plated cables for sound enhancement). But you have to be very careful since the design of earpieces requires a cable with a slim connector. In my test I used a silver-plated cable from Lunashops that fits right in, but some other cables might not work. Just keep in mind, if you are using a replacement cable and its connector can't spin freely - it's too thick for UM Pro or W series.

As I mentioned before, Westone earpieces (both UM Pro and W series) are among the most comfortable IEMs I have tested to date. They fit right inside of your inner ear cavity and sit comfortably with wire coming up wrapped behind your ear. Nozzle is very slim, which makes it incompatible with a lot of other universal eartips, but considering amount of tips included with UM Pro 30 - you have nothing to worry about. I intentionally chose a clear body version of the UM Pro 30 to demonstrate inner guts of the design where you can clearly see all the wiring and drivers, which includes a large BA driver (most likely for the bass) and two smaller BA drivers (for mids and treble). I think clear shell of these earpieces adds a nice touch to the design, and actually looked cool with my replacement cable.

Of course, just the looks and comfort will not be enough to justify its price tag without a sound to back it up. UM Pro 30 has a well balanced warm sound signature with smooth clear details and enhanced mid-bass emphasis. It is very impressive for a BA driver to deliver a bass quality equivalent to a warm dynamic driver. Starting with a low end you get an excellent extension down to a deep rumbling sub-bass layer and a fast attack of a punchy mid-bass. It's not quite at basshead level, but there is definitive a well controlled mid-bass slam that going to put a smile even on bass-head face. Mids are placed slightly forward, have a warm smooth full body sound, and nicely balanced with plenty of clarity and details without too much brightness. Vocals have a great full body presentation and sounds very lush and smooth, not even a hint of sibilance or harshness. Treble falls a bit short with just an ok extension and some early roll off, still clear but not as crisp - perfect for extended listening period.

Sound stage is very intimate with an average width/depth. These are clearly performance monitors where you want to have a more focused sound. Interestingly, I found width of mids/vocals sometime varying between tracks depending on layering with other instruments. You can almost call it an intelligent staging. Positioning/imaging was really good with a convincing placement of instruments, but in my opinion separation was just average due to a warmer nature of the sound which sometimes could be perceived as a bit congested in complicated passages of the song, very typical for this sound signature.

Of course, I couldn't pass an opportunity to put UM Pro 30 against some of my other multi-BA driver and hybrid IEMs for comparison. Once thing I found in common right away, all these IEMs were more "consumer" tuned with a wider soundstage which in contrast UM Pro has it more narrow and intimate. Looking at IM03 I found it having a similar sub-bass, but mid-bass was slower and slightly reduced, mids being leaner and brighter with a little less body, and treble a little crispier. W40 was another good comparison where I found less sub-bass, much slower mid-bass with lesser bass quantity, thinner and brighter mids, and more extended and brighter treble. Moving to A83 hybrid, I found it having less sub-bass and scaled down mid-bass quantity; mids were leaner and more detailed, and treble brighter and more extended. Last but not least, A71 had a lot more mid-bass bloat (in relative comparison), mids were thicker and less detailed, and treble was actually warmer and less extended.

Overall, I was very impressed with a design and a performance of UM Pro 30. It feels like I went through a rollercoaster ride, starting with preference for bass-heavy IEMs, then moving to a more reference/analytical sound, and now realizing that I miss my bass and want a more controlled enhanced low end. Until now that was only achievable with a dynamic driver or hybrid (with dynamic driver for bass) IEMs. Multi-driver balanced armature IEMs were typically bass-light. Some were able to deliver a great low end, but never being able to achieve fast attack in mid-bass. UM Pro 30 nailed that with flying colors! And on top of that you also have a well balanced clear upper mids without taking a v-shape route. It's very obvious that intent of this tuning was for an artist to be able to monitor vocal performance and still have a clear rhythm of the drums without missing all the important details. In general, the tuning signature of UM Pro 30 is perfect for modern genres such as EDM, Top40, Pop/rock, r'n'b and hip hop. It might be a little too warm and thick for a more analytical listening of those who prefer bright and crisp sound. I imagine that going up to UM Pro 50 with additional drivers (5 BA drivers) will put you closer to that goal at the expense of a higher price. But if you are after a smooth clear sound of BA drivers with a warm fast bass similar to dynamic driver performance - UM Pro 30 will be in-ear monitor for you!

My requirements are good isolation, excellent sound clarity 7 July 2014
By Mark G. Gibson - Published on Amazon.com
Verified Purchase
I'm a bass player and backing vocalist with a 7-piece band and bought these for use on stage. My requirements are good isolation, excellent sound clarity, good all-night fit, ruggedness, and not getting in my way on stage. By the same token, even though I'm a bass player I don't want over-emphasized boomy bass that muddies up the mix and prevents me from hearing the vocal blend.

These guys deliver on all counts. I've had trouble even getting earplugs to fit my weird-ass asymetrical ear holes, but these came with so many different tips that I was able to get a great, comfortable fit in reasonably short order. The clarity is great -- I can hear everything I need to.

FWIW, before spending the money on these I tried some consumer-grade Sennheisers, which were decent for isolation but weren't "real" in-ears IMO as they didn't have cables that wrap around the ears and couldn't be cleaned out. So if you're wondering whether there's a difference between in-ear "style" buds and actual pro-grade in-ears, the answer is definitely yes. But do you need the $$$$ 4-driver version? I certainly don't.

One caveat -- and I think this probably goes for all in-ears -- your bass response is VERY dependent on the seal with your ear canals. Bad seal = no bass.

And one last comment -- since we don't mic our drums, I don't want 100% isolation. I find that I'm able to pull these guys out a little and get just the right amount of bleed from the drums, without losing my bass. That's a good thing as these guys have allowed me to turn WAY down on stage, which helps everyone else hear each other better while the house PA does the heavy lifting.

Last point: I run these wired with a little headphone amp and a cable to the board combined with my bass instrument cable. Having in-ears doesn't mean you need a mega-buck wireless system.
