Sound:
The Bass resonates in my ears with a pleasant vibration, it's clear no distortion or muddiness. These devices usually don't have much in the lower frequencies, but these do a good job making you feel the impact.
Mids are forward and well detailed. Vocals male and female are presented with a nice balanced tone.
Treble has a great extension; it presents with good balance.
Soundstage of course is wide open and accurate. Music is immersive but the outside world still can be heard and this makes these better for outdoor use.

Conclusion: The Runner pro2, has a nice brighter sounding tone with good deep bass and clear mids. This is a very good sounding Bone Conduction unit, with a fun pleasant sound and nice details.
