# Etymotic ER4XR – A$175
At A$175, this ER4XR sits right at the median of recent comparable listings (A$173), making it fairly priced for the current used market. The ER4XR typically commands A$160–A$190 secondhand, so you're not overpaying here. That said, the asking price assumes good condition; any wear to the nozzles, cable, or driver degradation should knock A$20–A$30 off your offer. For context, these earphones hold value well because Etymotic's house sound—clinical, neutral, detail-forward—doesn't age, but they're fussy about fit and seal.
Before committing, verify the cable isn't cracked or corroded (common stress point at the jack), confirm both drivers pass a quick left-right balance test, and establish whether the original foam tips and comply adapters are included. The ER4XR's isolation depends entirely on fit; if the previous owner struggled with seal, that's a usage pattern worth understanding. Ask how many hours they've logged and whether they've ever been serviced or had the nozzles replaced.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Etymotic
Founded in 1983 by Dr. Mead Killion and Edwin DeVilbiss, Etymotic emerged from deep roots in acoustic research and the hearing aid industry. The company's name—derived from Greek, meaning "true to the ear"—reflects its engineering-driven philosophy. Headquartered in Elk Grove Village, Illinois, Etymotic is now part of Lucid Audio, a privately held parent company. The brand pioneered insert earphones in 1984, initially developed as diagnostic instruments for hearing assessment and auditory research before transitioning to consumer markets.
Etymotic's product portfolio centers on precision earphones and in-ear monitors, establishing the company as a specialist rather than a generalist audio manufacturer. Beyond consumer earphones, the brand produces hearing protection, personal sound amplifiers, and professional-grade insert earphones for audiometry and speech-in-noise testing. The 1991 release of the ER4S and ER4B marked a watershed moment, introducing the first commercially available universal-fit in-ear monitor to the world. The company has maintained a singular focus on single-driver earphone design while competitors embraced multi-driver configurations.
Etymotic occupies a respected niche within the audiophile and professional audio communities. The brand is recognized for uncompromising sound quality and clinical accuracy rather than mass-market appeal, positioning itself as a high-fidelity specialist. Its reputation rests on rigorous acoustic engineering, medical-grade heritage, and a loyal following among musicians, audio engineers, and discerning listeners who prioritize transparency and precision over consumer-friendly aesthetics or marketing hype.
