Etymotic ER4 XR Headphones - In Ear Monitors Used sparingly, these are immaculate. The only pair or silicon ear tips that I used, out of the MANY that come with it, was washed thoroughly with dishwashing soap and disinfected in alcohol. If you do some research you will find that these are among the most accurate in-ear monitors out there, besting products that retail for thousands of dollars. Also, quite easy to drive.

# 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.
