Apparently Apple are working on a wireless headphone, probably over-ear but I don't know really. I wonder if they will find some way of implementing something similiar to LDAC? Noise canceling is to be expected but apart from that we don't know much. I'd like to see some new functionality that make them stand out, but I'm guessing it could be a homerun for them if they "just" nail the noise-cancelling and make sure they sound better than Beats.
