View source for Ultimate Ears UE-10 Pro

These in-earphones are specially custom made to fit my ear canal. Each piece consists of 3 drivers; two low-mid-end drivers in parallel to balance the load and a single high-end tweeter. The crossover is handled by passive low-pass and high-pass filters respectively. A resistor in the passive crossover network flattens bass curve to make the low and midrange frequencies align better with the highs.

As you might imagine, the audio quality, soundscape, and compact size is something else, just pure bliss to use.

== Models ==
I first tried the UE-5 (two drivers) but they didn't fit right. After getting a new imprint and a second set of UE-5 the sound was still not right and as clear as I imagined.

The nice people at Ultimate Ears (thanks!) let me keep the two previous UE-5 and upgrade to the UE-10 Pro (for a small fee). The audio difference was noticeable better. It's been my favorite earphone since I got them in April 2005 (as of writing Sept 2011).

The UE-10 Pro has since been upgraded to UE-11 Pro.

== Color blend ==
Since the entire casing is custom poured, the color can be mixed and blended to your own preferences. I chose transparent body with a black colored end-cap, a nice neutral match and you can still see the insides.
