Shokz headphones, any better than the original Aftershokz and titaniums before branding change?

[Time Waster]

I have what we're top of the range bins conduction headphones, model was titanium made by aftershokz. Decent idea but sound isn't great.

Now there's newer models and a new brand name of just Shokz. Anyone got one and one of the older models? Have bone conduction headphones got any better?

In my opinion each model has been slightly better than the last, I think my current model is the air pro.
