No earphone on rift s? You are turning your back on alot of potential clients!
Removing headphones is just ridiculous!
If using the gear in a large space, in a room with other people (like an arcade)
If you live with family or just live in an apartment with thin walls! Having earphones is a must! If you really want to sell your product to a wider range of people you need to consider real people's constrictions. The whole idea of putting a universe into a head set is to be able to get away and emerce myself in another world! In most places I have lived, due to high amounts of traffic, even with fairly good insulation, the noise of the city is 40 db and up, I have often found myself , in the middle of the day putting my tv on nearly full volume to be able to hear it. And at night turning it down very low or putting on head phones so as not to get complaints from the neibours! And this was living alone in a house in the middle of a city.
I know that for the moment you are only selling to the top 1% but if you wish to expand your market you need to take into account the restrictions the average Joe has to live with! Also sitting mode and hand tracking are a must in these cases! After trying out your oculus rift in an arcade I was planing to buy myself one for Christmas but without earphones and sitting mode I have changed my mind. And I am certain that a lot of parents after seeing this change will make the same division and buying the rift now is pointless as it is just a matter of time before you stop selling the replacement components as you are now selling your new model.
Stay grounded or be replaced!
