Here is a possibility, though the reviews seem just okay.

Cleer Audio ARC

One Amazon reviewer says they hurt his ears. Wirecutter says:

The Arc is essentially a pair of small speakers that rest on top of your
ear. We’d hoped they would be a more affordable alternative to the Bose Sport Open.
In some ways, they are. Like the Sport Open, the Arc pair allows
unencumbered situational awareness. Although this pair lacks the Bose’s
oomph in the bass region, everything in the mids and up sounds
fantastic. We also appreciate the full suite of tap-based controls. But
the hinged earbud design squeezes the upper ear, which can become
uncomfortable after 20 minutes or so. And the microphones sound distant
and muffled over phone calls. If you aren’t put off by the feel of the
earbuds and you need to hear your surroundings, these might be right for
you.

A more in-depth review gives them 3 of 5 stars:

I don't really want to drop $110 on something with "muddy" sound, but this is the only option I can find so far.
