I believe the problem is jitter. Audio professionals know that improving the accuracy of the clock subsystem will improve the stability. When you are using wireless data, you have to have a very large buffer and attempt to synchronize a stable clock to data coming in over the radio which is inherently jittery. It would be difficult to embed a stable clock in an earbud; the most stable clocks are crystal based and about the size of the earbud itself.
The size of the actual DAC circuit is small enough that one could imagine a custom IC that would put the DAC, the radio, and the amplifier on the same sliver of silicon (but it would be pricey to do a custom IC). But you'd still have the problem of a sizeable off-chip crystal to get a stable clock
