Sleep-focused wired in-ear earphone

The EN3900 is a lightweight wired earphone designed for comfortable overnight use. Its soft silicone earplugs and low-profile shape suit listeners who want audio while lying down. The 3.5 mm plug connects directly to phones, tablets or portable players without adapters. At roughly 30 g it adds minimal pressure during extended sessions.

1.2 m cable with inline control

A 1.2 metre TPE-sheathed cord provides enough reach for bedside or pocket placement while keeping slack manageable. The inline controller handles play, pause and volume without unlocking the source device. Pure copper conductors reduce interference for clearer signal transmission. Output power is rated at 3 mW, so very loud environments may exceed comfortable headroom.

32 ohm impedance and 110 dB sensitivity

The 32 ohm load pairs easily with standard headphone outputs on smartphones and laptops. Sensitivity of 110 dB delivers ample volume from low-voltage sources without extra amplification. Frequency response spans 20 Hz to 20 000 Hz through a 10 mm driver. Buyers needing wireless freedom or active noise cancellation should consider other form factors.
