Conclusion: I own many balanced armature IEM'S, predominantly Etymotic. The Westone UM10 was my first choice for getting to know the Westone brand. Sonic Electronix provided excellent service with the lowest price that an authorized dealer is allowed to charge. I highly recommend doing business with them. The UM10 appears to use transducers that are similar if not identical to other low-to medium priced IEM's, such as the ETY HF5.
Summary: I was pleasantly surprised with the UM PRO 10 Earphones. Terrific clarity, no muddled base that covers up the real music. I wear these when I work out and the fit is great, you don't even know that your wearing earphones. All in all a great product for the price.
Summary: Really nice, quality, reasonable priced headphone. Been researching for replacement for an ancient SE210 with its dinosaur size cable. Been impressed with so far, small profile = nice fit, good clear sound = listening pleasure, Made in USA = quality you can trust. And he replaceable cable is another star, the UE900 with mic and control cable fit perfectly with the UMPRO10.
Summary: Nice earphones. Good balanced sound, bass not especially pronounced as I usualy prefer. Comfortable even if it's not as small as the Audéo's from Phonak. Stay aware: they're very loud with a 122db and I wouldn't recommend to listen over hours at full power! I like the fact that you can replace the cables if necessary. Over all I'm satisified with the Westone UM PRO 10.
Summary: I purchased these for my wife and she has been very happy with them. I also took a listen and was quite impressed. I have owned two pairs of Shure in ears (an old pair of single BA driver ones and the SE 315s) and now own a pair of Westone 4rs. Based on my previous experience with single BA driver in ears, I was afraid that these would be lacking in the low end. My wife loves the fit of the Westones however and our budget for these limited me to one option.
Summary: I had purchased these IEM's as a replacement for my old W1's that had been destroyed. The fit on these was great. Their small size made them very comfortable in my ear, almost to the point that you didn't feel them at all. I primarily bought them for working out so between the size and the sound quality they were a winner. After a few weeks however I noticed that monitors would constantly cut out after heavy work outs.
Summary: I bought these to use as IEMs with a personal monitor mixer when I play bass. The sound quality was good during sound check, but when the performance started, a lot of the sound was lost- predominantly on the low end. For a guitar player or vocalist, these would be a good IEM, and for most people they would be a great earphone, but they simply aren't powerful enough on the low end.

Design & Build Quality
The UM PRO 10s are well built and look as good as most other IEMs but this is by no means the best part about their design. What I like about the design of this IEM is the compactness, Westone have clearly taken their time designing an IEM which is as small as possible with no compromises.
Summary: I bought these as replacements for my ever-failing Shure se215. As much as the sound quality of the Westones is touted here, I figured I'd shell out more money to snag these UM PRO 10's. While I like the shorter cable as compares to the Shure's, the overall sound doesn't match the se215, unfortunately. I am using the largest silicone tips and have a great seal within my ear canal. I'm wondering is the smaller overall size of these earphones accounts for the lack of bass?
