I bought these for the transparency mode feature, because I figured it'd be helpful for traffic awareness for bike riding. I found that the mic picks up all the wind from riding, making the transparency mode totally useless. That being said, they're still great for cycling without transparency mode. They can still let outside noise in, or you can just ride with one earbud in.
I found the fit can be a bit fatiguing in your ear canal over long periods of time.
The ear wings are very flexible and can be bent to stay and make for a snug fit. These wings may also make the buds move off the charging elements when the box is closed. Make sure they're tucked in a bit more, otherwise, your buds will keep connecting to your phone and stealing its audio.
Touch controls are easy to activate. I like being able to control the volume from them.
