Product code: Bang & Olufsen U70 cheapest Stereo Planar Magnetic Headphones, Modded Damping, (Black)
The B&O U70 is a classic headphone and was on display in the Museum of Modern Art in New York as an example of design excellence. It has orthodynamic (planar magnetic) drivers in it and sounded pretty good, except for a lack of bass. I have adjusted the damping materials in the headphone to give it much better bass, and you can see it from the cheapest measurements I'm attaching, showing the frequency response before and after the damping, where red is before (original damping) and blue is after (my damping). It took me weeks to figure this out, but it was worth as the headphones now sound very very nice. Because the earpads on most of these have had the thin pleather deteriorate (many people sell them with just the white cloth earpad underbase, which sounds terrible), I searched to find the perfect pair of earpads that were comfortable, complemented the sound, and fit the chassis. I finally found the pair which is included. *Burgundy headband* No box, case or stand included. (A).
