Thanks for the reply, Eric. I do have some brand loyalty to Sennheiser since they were my first foray into higher-end headphones. The next pair I get for sound quality purposes may be Sennheiser again.
I think I'm still drawn to bone conducting for cycling, though I think I'll go with the more prominent brand in this space, as opposed to the ones I linked to in the original post.
