That may be a fair-point then.
Most VR games are fairly short (about 3 hours) and there's very few very good ones. RE7 is the best, and you may want to think about Batman VR too.
The recommended headset does come with two-headphone plugs - one for the games sound and one for the controller sound (as the controller has a speaker) but very few games use that speaker and none of the VR games I've come across, so it's probably a negligible point. It does "fit" with the visor though, so a bulkier pair of headphones might not be as comfortable, but again, I'm sure it's a minor point.
There's a few things to think about - you will very likely sweat, this is just because you wearing an enclosed helmet pretty much, which means that the goggles will initially fog up - it usually takes me about 5 minutes of cleaning the fogged up glasses before I can use it properly. This is partly because Australia is a hot climate, and partly because I have some fatty tissue on my face, but mostly it's just an unfortunate side-effect of the apparatus.
There is a very real possibility of motion sickness - I am not really susceptible to it, but I've read stories of people with constant headaches and vomiting - if you think you might be a bit sensitive to this stuff it's definitely worth trying before you buy, because the sacrifice probably won't be worth it.
While I don't get motion sickness I do get eyestrain and sometimes a dull headache or neckstrain if I play for a long time (I think the longest session I've had is probably about 2 hours at this point) - I think this is purely a symptom of the fact that you have what amounts to a television screen right in front of your face for a few hours. I'm sure it varies person to person, but, again something to consider.
The final thing to point out is the technology is good, but new - the playstation has a lot of options in order to adjust the set for your comfort (including an option to measure the distance between your pupils and reset the screen to match that) - with that said, there are some minor niggles that you will come across like resolution "snap in" where everything loads in low res and then readjusts, and sometimes you will be warned that you're exiting the "play area" or that your head has moved "out of position" which means a large controller flashes in front of your eyes indicating a direction you need to move in to get back in line. As far as I can see, this is just a software problem with the sensors and will likely get fixed in a future system update, but it can be a minor annoyance.
