Tech: Shokz OpenRun Pro 2 headphones

The marathon has come and gone, but I'm still running for fun, and the best headphones I've found for the job are the Shokz OpenRun Pro 2s:

They're "hybrid" headphones - a combination of the bone conduction technology that Shokz is famous for, plus more conventional air conduction drivers that direct sound into your ears the old-fashioned way. That makes the OpenRun Pro 2s sound noticeably better than old Shokz models, yet they still allow you to hear everything around you...the rustle of trees in the wind, the roar of a crowd near the finish line, and (most importantly) that garbage truck coming up behind you.

Downsides? The sound quality still isn't as good as a traditional set of headphones, and yet the OpenRun Pro 2s are quite expensive - around $150.  If you just need something for working out inside, you can find better-sounding earbuds for a fraction of that cost.  However, after using these for hundreds and hundreds of miles of outdoor running, in all weather conditions, I do think they are worth the money.
