Pros: - Very good audio quality for bluetooth earbuds, only a slight downgrade from wired Klipsch S4 series - Decent battery life, ~6h, and quick charging

Cons: - Connection with iPhone and MacBook Pro was good at first, but has seemed to degrade over time. Lots of dropped connections with the phone, though it usually picks it back up. With the mac, lots of hiccups in the connection.
