Offline Music on the OnePlus Watch 3: What You Need to Know

OnePlus has advertised offline music support for its Watch 3 series. While that’s technically accurate, there’s a catch: the feature is not directly accessible through the watch settings or the OHealth app. If you’re someone who assumed you could simply drag and drop your MP3s onto the watch, you’ll be disappointed.

There is no native file transfer menu, no simple sync option, and no mention of how to get music files onto the device  a surprising omission considering earlier models had this ability.

What’s Missing from the Official Setup

Despite having the hardware storage for offline files, OnePlus has not provided an official method to transfer personal music files to the watch. Users will find no music transfer option in the Wear OS settings, and the companion OHealth app offers no such functionality either. This issue is not new; it also affected the OnePlus Watch 2.

Ironically, the original OnePlus Watch did have basic offline music support through the OHealth app. That feature, however, did not carry over to the newer models. The likely reason is that OnePlus expects users to rely on streaming apps like Spotify and YouTube Music, both of which support offline playback for premium subscribers. But for those who have a library of MP3s, independent artists, or offline-only podcast episodes, this lack of support is a real limitation.

The Best Workaround: Using Wear Casts

Thankfully, there is a practical solution. Because the OnePlus Watch 3 runs on Wear OS, it supports third-party apps from the Google Play Store. One of the best options for offline audio is Wear Casts, an app originally designed for podcasts but also compatible with MP3 files.

How to Set It Up

1. Install Wear Casts on your Android phone.
   This app is available on the Play Store and is free to download.

2. Connect to your OnePlus Watch 3.
   Once installed on your phone, Wear Casts automatically pushes a companion app to your watch.

3. Upload Files or Subscribe to Feeds.
   On your phone, you can either upload MP3 files manually or subscribe to podcast RSS feeds.

4. Transfer Audio to the Watch.
   After selecting files, the app downloads them to your phone and then syncs them with the watch. You’ll be asked to grant file permissions the first time. Accept the prompt to continue.

5. Playback Options.
   Audio can be played over the built-in speaker or Bluetooth earbuds. Wear Casts also offers scrubbing and skip functionality depending on the file format.

The process is not seamless, but it works reliably once set up. It’s a solid workaround until or unless OnePlus decides to reintegrate native music transfer tools.

Is It a Dealbreaker?

For most users, probably not. The majority of smartwatch owners likely stream their music using Spotify or YouTube Music. These services provide a smooth, integrated experience with offline caching as long as you have a premium subscription.

However, for audiophiles, podcast enthusiasts, or users who prefer storing personal media on their devices, the lack of native file transfer is a frustrating limitation. That said, using a third-party app like Wear Casts does effectively bridge the gap.

While it’s not a dealbreaker thanks to third-party apps like Wear Casts, it does introduce unnecessary complexity.
