Summary: These earphones are use by the pros for monitoring music but are great for personal use with an MP3 player or hi res player. Sound is sharp and clear and ambient noise is controlled well. Good quality at a comfortable price.
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.
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.
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!
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.
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.
