Headphones OMEGA FH4008BL — wired headset for calls and music

OMEGA FH4008BL headphones are a wired headset designed for clear voice calls and everyday music listening. The model features a built-in microphone mounted on a boom for reliable speech capture, a comfortable adjustable headband and a detachable adapter that converts two 3.5 mm plugs into a single 3.5 mm connector for use with smartphones and tablets. With 40 mm speaker drivers and an Extra Bass System, these headphones offer balanced reproduction across a 20–20,000 Hz range and are intended for use with notebooks, desktop PCs and mobile devices that accept standard audio connections.

Advantages

The FH4008BL combines a robust 40 mm driver design and an enhanced bass system to deliver deeper low frequencies while maintaining mid and high clarity. A high-sensitivity transducer (116±3 dB) and 32 Ω nominal impedance allow efficient playback at typical consumer volume levels. The boom microphone and included adapter make the headset versatile for both desktop setups (separate mic and audio jacks) and single-jack mobile devices. The adjustable headband and quality construction provide extended-wear comfort and durability.

Usage recommendations

For optimal voice clarity, place the microphone 1–2 cm from the corner of your mouth and avoid breathing directly onto the mic. When using the adapter with mobile devices, ensure the plug is fully inserted to prevent audio cutouts.
