As a kid growing up in Milford, Michigan, my big brother always had the classiest clothes, latest records, and sharpest gear. He danced in Cuban-heeled leather boots, I climbed trees in lace-up Keds. He spun Rolling Stones vinyl on a fabric-wrapped Zenith portable with detachable speakers, I blasted the Beatles from a tinny transistor radio. Ten years my senior, big bro drove a Buick bomb (which, late one night, mysteriously caught fire in the garage) and had a girlfriend, Gail, whose plump cheeks and smart clothes embodied modern mid-century Midwestern appeal. I like to think that my brother and I have both aged gracefully. And lately, he's taken to high-end hi-fi with a passion.

Headphone listening has always been an important part of my audiophile life. In recent years I've been using at home Audeze's large, open-back, circumaural LCD-X headphones, which I bought after reviewing them for the March 2014 issue; and a pair of small Ultimate Ears 18 Pro in-ear monitors, which provide much better isolation on my subway commute to Stereophile's offices in Manhattan. I was intrigued by Audeze's iSine in-ear models, which were introduced in November 2016 and are unique in using planar-magnetic drive-units mounted outside the ear. I thought about reviewing a pair of the affordable iSines, but before I could get around to it, I heard that Audeze was to launch a cost-no-object version, the LCDi4, priced at a substantial $2495/pair. Aspiration got the better of frugality, and I asked for a pair to review.
