Etymotic ER4 SR Product Review

Patrick Sheridan - International Soloist and Recording Artist May, 2017

I have been an over the ear headphone user for many years, so I was skeptical about what would be possible in an earphone for realizing the accuracy of sounds I listen for when using headgear rather than speakers. I guess the proof was in the first use – after getting the fit correct with the options available, they were in my ears for the rest of the day.

WOW! What clear fidelity!!

Excellent tones in a wide range of musical styles make me forget I’m wearing anything. For noise isolation, the foam tips work great when flying or in other high noise environments. The 3-flange eartips are comfortable for less isolation. I’ve been really impressed! Most recently, I used them for a recording project in post production (with a DAC headphone amp) and never felt I lacked for anything during the process. In fact – when driven with a DAC headphone amp, these earphones are truly outstanding. I was able to compare in this format with other earphones at twice the price (with half the options for comfort and isolation) and the ER4 SR’s won in every respect from fidelity to comfort. The storage case is convenient for travel and well made for protection.

BRAVO, Etymōtic! Thank you for your contributions to musical enjoyment and hearing protection!!
