It used to be that (IEMs) were something reserved only for superstars. But – in case you haven’t caught much live music lately – a rising tide of musicians don’t go onstage without them. The only drawbacks have been their astronomical prices and getting custom ear molds to ensure a proper fit.

Ultimate Ears Pro has long established itself for making an impressively wide range of custom IEMs so sophisticated that many pro musicians and weekend warriors have made them their go-to brand. And in case you’re wondering, they’re fully aware of the obstacles that prevent musicians from taking the plunge toward IEMs, which is why their new affordable line of premium in-ear monitors – the UE 150, UE 250 and UE 350 – feature a universal fit that offers an exceptional trinity of sealed-in comfort, high fidelity and durability. Tackling a universal fit for all three of these IEM models is no small feat, which is why UE Pro employs their proprietary PerForm Fit (a unique, universal-fit design developed from their experience of gathering well over 175K ear scans) that, according to the company, “minimize ear fatigue and irritation while maximizing sound quality and sound isolation” and ensure a secure, comfortable fit that won’t fall out of your ears.

All three IEMs come with an assortment of foam and silicone tips in every size (XS, S, M and L). I’d suggest trying on each size to find the appropriate fit for your ear canal and testing the foam and silicone tips. In .
