Etymotic Research ER3SE In-Ear Headphones Overview

With a heritage based in the world of diagnostic hearing measurement and protection, Etymotic’s (et-im-oh-tik) in-ear phones are among the most precise and revealing on the market today. They are so accurate, says a reviewer, that they “peel back the layers of every song” to reveal the most subtle nuances. The ER3SE’s tips have multiple flanges to maximize noise isolation; replaceable filters smooth the frequency response while protecting the drivers. Multiple eartips offer long-wearing comfort, top build quality ensures long life, and high efficiency means nearly any portable player can drive the ER3SE. (If you prefer your music with a bit more warmth, Etymotic offers the extended-response ER3XR with a modestly augmented low-end.)

Among the best noise isolation on the market

The triple-flange design of the ear tips sits more securely in the ear canal, and is designed to trap external noise and distractions. It does so with the most effective passive noise reduction on the market – specified at 35 to 42 dB of isolation.

Micro-drivers offer a revelatory experience

Etymotic, founded in 1983 in Illinois, got its start in audiometric testing equipment and hearing aids. That heritage carries through in the ER3SE, with professional-grade, balanced-armature drivers to deliver ultra-fast and accurate (even analytical) response without generating extra air pressure. They’re incredibly efficient, and safe for long-term listening at reasonable levels. (But remember, you should never listen too loud for too long from any source.)

Built to last

The ER3SE’s precision-machined metal bodies and anodized finish are designed for long life. The 4-foot cable with gold-plated 3.5mm plug is reinforced and detachable for portability and easy replacement. And unique tiny replaceable filters protect the micro-drivers from dirt and damage while helping to smooth the frequency response.

Ready to roll

The ER3SE is fully equipped right out of the box. You get a set of replacement filters, a filter replacement tool, an assortment of isolating ear tips to best fit your anatomy, a shirt clip and a convenient carrying case to pack it all along. And, as we recommended earlier, if you prefer your music with a little less analysis and a little more oomph, give a listen to the otherwise-identical ER3XRs.
