These earphones may look amorphous (and a tad gross) but that's because they're the UE-10 Pro Ultimate Ears, which have been custom-molded for the individual user's ears. An audiologist makes impressions of your ears, and the Ultimate Ears arrive, perfectly ear canal -shaped, in any color you like, about a week later.
Ultimate Ears were designed for use as sound monitors for musicians and sound engineers so they have excellent noise-cancellation and provide superior sound accuracy.
What's the price for the ultimate? $900, about $50 more than the similar, but nicer-looking Sensaphonics Custom In-Ear Monitors.
