Kuulokkeet Deltaco HL-51

The Deltaco HL-51 wired headphones provide a focused listening experience for users who prefer a reliable, cable-connected solution. These circumaural, head-band style headphones cover the ears to deliver a frequency response of 20–20,000 Hz and clear audio reproduction for music and everyday audio playback. The 2.5 m cable gives extended reach for use at a desk, in home setups or near audio sources, while the lightweight 215 g construction aims to reduce fatigue during longer sessions. The matte black finish offers a neutral, functional appearance that fits multiple environments.

Wired connectivity provides consistent signal transfer without the need for pairing or battery charging. The long cable length supports flexible positioning relative to the connected device, and the light overall weight contributes to comfortable wearing over extended periods.
