Do you have the same musical taste as your wife? I have a bone conduction headset that I use for cycling. Podcasts and ebooks sound fine, and some music is acceptable (a lot of classical, some pop and folk). Anything with bass just sounds like garbage though - don't bother with any hard rock, hip hop, or anything else with bass.
I tried out hers to see if I liked them, and am not sure which make/model it is. I'll ask her when I get a chance. I do remember her saying they cost about $125 so not cheap, but probably not high end either
