I've switched entirely to Bluetooth headphones, but I'm with you - there are plenty of downsides to wireless headsets even with lossless audio protocols like aptx. And water resistance is still possible - my Z5C can be used in pouring rain and it still has a 3.5mm jack.

I'm also worried about the potential for consumer-hostile DRM on audio playback, especially since it looks like they're introducing their own proprietary wireless protocol.
