If Giga went 3 blocks, Mega went 4. When Giga went a block and a half, Mega went two blocks. At the extremes of its range, the gigaphone had background buzz and occasional bleeps, but my old faithful 7890 maintained perfect audio. The new models are very nice, with near-perfect sound and a range of useful features . 2.4Gig is probably perfect for most people , but for the moment, it won't replace my KX-TD7890.
Range depends on local reception conditions.
