Etymotic Research hf2 & hf5 in-ear headphones
Ah, how the times change. When I reviewed Etymotic Research's ER-4S in-ear headphones in the July 1995 Stereophile, they seemed expensive to me at $330, but well worth that seemingly high price: at the time, they were the best headphones I'd heard. Nowadays, with reference headphones costing well north of a kilobuck, the price of the ER-4S seems relatively reasonable.
