Q: what's your opinion on wireless ear buds
A: latency hasn't come down enough for it to be good enough for things requiring instant response to user actions. i.e. music production, or phone conversations, or any type of game where it's important to hear an instant sound response to something you did. they're awesome as long as you're just consuming audio tracks (listening to music, not interacting with it) because once the song starts (half second late) it doesn't matter if the whole song is a half second late. Even video watching is ok, because most video players are smart enough to buffer it right so the vid syncs right with the audio. But if you're recording music, you're still looking at at least a 200ms latency. can't play an instrument that way. And this is not good for intimate phone calls either, because as it is, in the digital world, all cell phone calls have about half second delay (or more) already. And this gets worse when you're doing international, or internet calling. wireless ear phones will add at least quarter second delay on top of that. however, besides all that, it is truly awesome to have no wires. but i'd say the latency probably isn't down enough to discontinue the headphone jack just yet
