Tokyo-based Dwango carrier has released new ringtones. Guess what, you will never be able to hear it because it is made to be sensed only by dogs.

Company officials believe their ringtones are absolutely astonishing products that will revolutionize the mobile phone industry. Japan has always amazed with weird designs and inventions but we can speculate on this product’s usability.

In any case, the service has a long Japanese name, but here’s an English translation: “Ringtones only dogs can hear”. Dwango subscribers can download it for free from www.dwango.jp. If you plan to use it, make sure your dog is around.
