I need to buy headphones - and maybe earplugs also. And that is because I need something for music and something for games. And luckily I have a considerable amount of money to spend
So I watches some reviews or headphones, did some thinking about my own personal usage and ended up with reading info like this: The Sound Card + Wireless Heaphones Dilema! | Tom's Guide Forum
Long story short - please correct my findings if they are wrong and please answer my questions:
1] If headphones / earplugs will be wireless then I will have to connect them by Bluetooth? Unfortunately up to this day there are still many issues with Bluetooth [https://www.youtube.com/watch?v=e3eVykPNGVg]
2] All wireless devices have mini-sound cards built in them? And so they do not need or even use onboard audio device of the PC or smartphone?
3] If I do want for whatever reason to use my external or internal PC sound card I need to plug my headphones / earplugs to it using mini-jack [Phone connector (audio) - Wikipedia]?
4] Manufacturers often do not list the frequency response / range. So I would need to seek outside a third party info about that
5] There are no wireless devices with frequency response above 20 kHz?
6] Could I force headphones to go through PC sound card with some specialized Bluetooth receiver which would have a cable with mini-jack [which I would plug into the card]?
7] If I want to have surround sound then I need devices with multiple mini-speakers built into them? Thus I should consider buying "typical" gaming headset for games [so that I would hear if enemies are approaching form behind] plus an "ordinary" stereo ones [for the purpose of listening to music] - because there is no gaming hardware who happen also to be leaning toward being an audiophile?
8] Assuming that I do not care for quality that much in games and do not play online [thus do not need an attached microphone] but just want to have surround effects - plus I like to play when laying in bed - thus for playing games I should consider using earplugs as they will be more comfortable when me head will lay on a pillow?
9] Assuming that I want to have the opportunity to hear the sounds above 20 kHz and want to avoid various interference and other problems - for music I should consider buying headset with a traditional cable attached to them?
10] Assuming that I want to have surround sound when watching movies - then I should use what? Is it possible at all to have surround sound in movies when using headphones / earplugs? [Of course I assume I need to have the movie file with an audio track in it being 5.1 or 7.1]
11] If the game does not support surround sound [like some older title] - then even the best hardware will fail at producing such effects? Or is this the time and place where a proper PC sound card comes in and saves the day [or at least fixes it to some degree] by emulating surround?
12] A long time ago [when I first tried to buy hardware but run out of money] a saved a note for my future self:
"Windows Vista and Windows 7 do not allow drivers to have native hardware access to sound devices. This is because Microsoft have re-written the audio stack in every iteration of windows since the NT Kernel. Windows 8 fixes this in a way, but any games that use EAX or Creative solutions are likely designed for XP and won't work properly. And any sound cards that possess true hardware acceleration and 3D effects has probably only 32-bit XP drivers which may or may not work on 32-bit vista/7/8 - so no 64-bit support". Are there still problems with this on Windows 10 x64? And what does this really mean - that the user has to relay on headphones / earplugs surround capabilities and not those of the PC sound card?
13] If I want to cut of myself completely from the sound environment when watching movies - I need closed headphones and preferably with active noise cancellation feature? But when I need to have only some degree of blocking of outside sounds when listening to music - the I can take a pass on the active noise cancellation and / or use open-back headphones? And when I do not care about outside noise - I should be pleased using just earplugs?
14] What about digital audio converter? How would I insert it into my equations? Can it be used effectively with wireless devices?
15] Overall: there are no jack-of-all-trades headphones / earplugs and in the foreseeable future there will not be?
[The last time I researched this topic I went to some audio oriented forums - and got too technical information and / or attitude of "we know everything and you know nothing so do not waste our time with you pitiful questions". Plus back then I was only thinking about music]
