Using the single cord is one of the best hands free options I've ever used.

I had a nice set of Bose earbuds I had previously used for serious music listening.

They stay in place well using the interior side of the antihelix, and the cable gets routed up and over the ear

In terms of sound stage, they create a more intimate performance than I am use to with minimum sound

This is, without a doubt, the worst use of $400 I have ever had in my life
