With this smartwatch, you can receive text messages, calls, and all smartwatch notifications. Listening to Spotify with the offline app with its built-in headphones is also flawless. It comes with a built-in microphone as well, so definitely recommend it.
We also recommend a screen cover to protect the screen. As for the battery life, it depends on how you use your smartwatch, but this Samsung SM-R815UZKAXAR is excellent.
