Bang & Olufsen - U70 Headphone

This beautifull Bang & Olufsen headphone model U70 from designer Jacob Jensen is getting harder to find.

The headphones come in a rare original box. This U70 is in very good condition, all lettering is undamaged.
A real collectors item!

U70 headphones were lightweight (only 300 grams) and were very comfortable to wear, even for long periods. The ear cups could be individually adjusted both vertically and laterally and locked into position. Their height could be adjusted their height using the inner headband. The softly-padded ear cups were of the semi-open type and excluded most extraneous noises. However they were not so completely sealed that the user could not hear the phone ringing.

Technically the U70s had a power handling capacity of 2 watts RMS and used the ortho-dynamic principle to reproduce sound with all the accuracy and fidelity of a good loudspeaker. They were supplied with 3 metres of cable fitted to a 6,5 mm jack plug.
