I don't actually regret them, however they do not meet all my needs.
All pros and cons are only my experience:
Pros:
Comfortable for extended wear, I forget they are in at times.
Good sound reproduction for my expectation
Pull one out to pause, and reinsert track continues, great in an office environment.
Switches fairly easily between devices
Cons:
When running always adjusting them, jamming them back in my ears
Air travel, do not push sufficient volume for spoken word, podcasts, etc.
Wish they could be simultaneously connected to two devices i.e. watching a movie on an iPad and being able to take incoming call on phone.
I purchased a pair of Bose Soundsports and they are doing the job for running and air travel. Both look goofy, but I am of sufficient age that I don't care
