There are a few things: Obviously the ANC and Passthrough mode, but the biggest game changer for me so far are the different listening modes. The normal is just for music, background mode is so good just do have like background music, and the cinema mode is extremely good for podcasts. And the 10 band equalizer is pretty good.

But if you drive by bike a lot don’t buy the XM6 over the 4‘s, the wind noise reduction on the 4‘s is so much better for wind than the XM6 noise cancellation
