Idk, but I have two of them, the headphone jack needs to be bent just right to use it in stereo as they trended to fail. Loved how they feel, like puffy clouds on my head. Certainly not audiophile headphones and not fatiguing which I like.

Funny…I actually had these back in the day…liked the flat cord. One of the sides went out and they became useless

These things were awesome

I recently pulled my pair out of storage after years of not using them. Hopefully the pads last longer than the ones on my 7506s

The direct equivalent would be something like the WH-XB910N (the XB920N might be launching at some point soon), but, there’s a big but.

Sony has changed the overall mission and positioning of the XB series. They no longer make “extra bass” like they used to. If you liked the early XB (up till XB950) for their so-called “rumble” and “drive,” Sony has kinda given up on those parameters in the name of clean audio. So, if you can EQ, every Sony headphone can be made to push out very heavy bass, but none of them have the groove that the earlier XB models used to.

For this reason I have been chasing down older XB models like the XB950 (two generations, wired/BT and N1/B1), XB550 and the XB55 earbuds. Today’s extra bass Sonys just can’t compare.
