I'll be honest... Now that I fixed my UM3X with my hefty new 1400mw UV tool, I'm much happier. I also believe that the comply p-series is a must for absolutely iem..... The deep insertion widens the soundstage, deepens the bass, the vocals become lifelike, the isolation is superb, and its like the music is really inside of you.
what did you fix exactly?
Where the wire met the driver housing, the glue became lose, and the cable was rotating 360 degrees and was loose near the housing. A little UV adhesive and about 40 seconds of UV light and boom. Problem solved.
