$119 for Aftershokz Air headset, I believe lowest historical price (if not must be close).
Had these for 6 months and they are excellent for work and exercise. Naturally audio quality won't be as good as in ear or overear headsets, but I prefer these for comfort (I.e. ok to wear all day) and also to hear ambient noises e.g. traffic, other voices.
Converted many folks at my work all with great feedback. A few basic colours available.
