3ears website here.
This website has quite a few songs and video clips in Russian, with karaoke-style subtitles (those are also in Russian). The videos section includes, for example, a popular sitcom Кухня). The developers are also taking requests for songs and clips. In addition, they have a tool for creating vocabulary cards and interactive drills.
It can be used in class, but it’s also really effective in letting students work on their own, either at home or over the break.
Both students and teachers can also write directly to the 3ears team and ask for assistance.
