open ~/Library/Application\ Support/MobileSync/Backup

With Broom

Broom lists iOS backups under Worth a look with their sizes, never preselected, because only you know whether you still need one. Pick the old ones and they go to the Trash.

Keep the most recent backup of any device you still use, unless it backs up to iCloud.
