How is bone conduction different from normal earbuds?

Bone conduction sends vibrations through your cheekbone to the inner ear, leaving the ear canal open. You hear your audio and your surroundings at the same time. It trades bass depth for awareness.

Does the active noise cancelling work?

Only partly. With an open seal, ANC cannot block much low rumble the way sealed earbuds do. Expect it to soften steady background noise, not silence it.

Can I wear them running or in the rain?

Yes. They are water resistant and the ear loops hold them in place during movement. They are not rated for swimming or submersion.

Will people around me hear my music?

At higher volumes, yes. The open design leaks sound outward, so keep the volume moderate in quiet spaces like trains or offices.

Are they comfortable with glasses or a helmet?

The ear loops sit over the ear, so glasses arms and helmet straps can press against them. Fit varies by head shape; check that the loop clears your frames.
