For whatever reason, these don't work for phone calls on Messenger. We don't know if it's an issue with the earbuds or a compatibility program with Messenger because we have another set of earbuds, and those don't work with Messenger either. For all other uses, they work fine although the sound quality isn't excellent, it's just okay.
The coolest thing about them is that they're magnetic and stick together when not in use (so you're less likely to lose them).
They fit okay and are comfortable.
