Denon announced two new models to their current low and mid class IEM, the C260 and the C560. Denon claims that the use of different types of materials (including resin and aluminum) in the housing eliminates unwanted vibration and improves sound, though I really have my doubt how effective they really are. Anyway, that's why Denon is calling these models 'hybrid', not because it uses hybrid transducer or helps you save fuel. C560 should hits the street by May with C260 a month later. MSRP are estimated to be $86 and $32 for both models in Japan. You can expect the international price to be higher.
