Editorial note
The Etymotic ER-4B earphones stand out for their exceptional audio quality, offering a sensitivity of 108 dB and a wide frequency range of 50000 to 10000 Hz. This translates to clear and powerful sound, perfect for an immersive listening experience. Their in-ear design also ensures prolonged comfort, although some users may experience discomfort after extended use. The lightweight design of only 28 g makes them easy to carry, making them ideal for long listening sessions without fatigue. The 1.52 m cable offers flexibility of use, although wired connectivity may be seen as a drawback for those who prefer wireless earphones. Additionally, with an impedance of 100 Ohm, amplification may be necessary to fully take advantage of their sound quality, resulting in an additional cost. However, the price of the Etymotic ER-4B is relatively high compared to other models available on the market, which may deter some buyers looking for more affordable options. Finally, while their sensitivity ensures powerful sound, it can also make them sensitive to ambient noise, affecting the listening experience in noisy environments. In summary, the Etymotic ER-4B are high-quality earphones, suitable for audiophiles seeking an immersive sound experience, but their cost and wired design may not be suitable for all users.Score details
