Editorial note
The Etymotic Er-4s earphones stand out for their superior audio quality, offering an immersive listening experience thanks to a sensitivity of 108 dB and a wide frequency range from 50 Hz to 10 kHz. This model guarantees clear and powerful sound, ideal for audiophiles seeking optimal audio performance. Additionally, their in-ear design and closed acoustic system provide remarkable sound isolation, fully immersing you in your music without external distractions. In terms of comfort, the Etymotic Er-4s are lightweight, weighing only 28 g, making them suitable for prolonged use. However, it is important to note that some users may find the in-ear design uncomfortable after long listening sessions.
