If there are new messages, please pay attention to how to set mp3 as ringtone.

1. Let's first install itunes in the computer, then connect the iphone5s to the computer, then set "Devices" in itunes, and then click the ringtone option and put a tick in front of the synchronized ringtone.

2. Then, we click the file in Music in itunes-add the file to the database-and choose the correct path to find the music import.

3. By default, there are no ringtones in itunes. We can click "Edit-Preferences-Universal Audio Options" in itunes to check the ringtone.

4. Now let's click "Music" in itunes to find a song for which you want to set a ringtone, and then right-click "Show Introduction"-fill in the start time and stop time under the options, and intercept some music as a ringtone (the music as a ringtone should be within 40 seconds, so be careful when filling in the time).

5. Now, when we want to return to the music in itunes, right-click the song with ringtone and select "Create AAC Version". You will see a music clip you just intercepted, right-click it and select "Show in Windows Explorer".

6. Then, in windows resource management, we changed the file name suffix of m4a to m4r format and copied this music clip. Paste the copied music into the ringtone of itunes. The ringtone of M4r format iPhone5 is finished. Then connect to your iPhone5 and sync.

Ringtone setting method

After the ringtone is successfully synchronized, the ringtone will appear in Settings-Sound-Ringtone-Customize. To use this ringtone, just select it.
