We are not able to find this model on Denon Japan. From c751's specs and pics, it is very likely just the short cord version of C700, and/or is simply the model name outside Japan. Some Japanese companies (Canon, Stax) give different model name for the same thing when it is marketed outside Japan. The only new model (27Sep07) is the C551.   Ear canal buds fits snugly. Stays in place even during vigorous exercise, eg. jogging, treadmill. Blocks out external noises, creating an excellent inner ear acoustic environment.
