I don't have that specific model but I purchased the DJ596 MK-II and have been less then impressed. It receives and transmits well but operation is a bit of a hassle. You have to press one of the keys and then adjust the volume. The speaked sounds like something out fo a toy. The belt clip is part of the battery and broke off the first time I sat down with it in the car.
If I had to do over I would go with something else.
