The Jaybird X3 are overall great earphones,
personaly I use them mainly for sport activitys, -> cycling, jump-ropeing, freeletics.
I found to wear them overears more practicaly especialy , so they dont bump on my neck durning work out. In either wearing (over-under) they do not fall out or feel uncomfortable, since there are many adjustments possibilitys.
Water &sweatproof so perfect.
They pair fast, reconnect bythemselves and also to take, reject calls are easlily made.
only the disadvantages are , that I have hungups in the connectivity if I stay 5-7meters way from my sending device (one+ two) , even if no wall or obstacle is in my way. But I didn't experience them if my mobile device is on me or in my backpack.
The app is quite handy and any changes on the app do massivly influence your listening experience. - so its super versatile, to almost any like.
ps. I use Bose QC35, for my daily needs :) - as a reverence…plus
