Garmin Forerunner 245 vs 245 Music – Which is Better?

Garmin Forerunner 245 vs 245 Music
The 245 Music is a better smartwatch. It allows for onboard music storage which is not possible with the 245

From all indications, the Forerunner 245 and 245 Music are two identical smartwatches. These two have the same design, display, and size. The Activity tracking features are also the same.

However, the difference is that the 245 Music comes with a 4GB storage capacity that allows you to store your favorite tracks on the watch. This isn’t possible with the Forerunner 245.

With the 245 Music, you can load your personal music to the watch as well as load from music streaming services such as Spotify, Amazon Music, and Deezer which you can listen to offline using a Bluetooth headphone.

Beyond this, the Forerunner 245 and 245 Music will track your daily activities such as your steps, calories, stress, sleep, and heart rate. These two also have an inbuilt GPS that will allow you to track outdoor activities like routes and locations. The 245 and 245 Music also feature blood oxygen measurement and the ability to detect falls.

Meanwhile, the 245 and 245 can’t count floors and Garmin Pay isn’t supported as there is no NFC.

The 245 Music is a better smartwatch if you want onboard music storage. Otherwise, the Forerunner 245 is a cheaper alternantive.

Garmin Forerunner 235 vs 245

The Forerunner 245 is a newer and more equipped smartwatch than the Forerunner 235, and as such, it’ll cost you more. Yet the Forerunner 235 is still a nice cheaper alternative for keeping tab on your active life.
