True wireless earbuds are so convenient, but they're expensive. However, the Skullcandy Push Ultra earbuds are on sale for $59.99 on Amazon. These typically sell for $99.99.
The Skullcandy Push Ultra earbuds have features that you'd usually find on more expensive earbuds, but they're quite a bit cheaper.
Even at the full $100 price, Review Geek gave these a solid 7/10 rating and called them "A Solid Workout Companion."
Since these are designed for working out, they're IP67 rated. That means they're water-resistant, so you don't need to worry about sweat damaging them.
While the sound quality isn't the main focus of these earbuds, they offer solid audio as a great bonus.
