About the Product
Etymotic ER4-SR is the new reference standard hi-fidelity earphone for those who demand nothing less than the highest fidelity. This next generation ER4-SR delivers increased accuracy with greater sound output.
ER4S earphones are designed to compensate for the high frequency emphasis in recordings. Performing musicians often use them because the response matches that of most monitor loudspeakers.
