I am normally a lens wearer. However, even with my glasses, I have no problem with the headphones.
The G G432 completely encloses the ear. Depending on how thick the earpieces are, they are more or less bulky. But since the G G432 is very well padded, this should not be a problem even with somewhat thicker/firmer earpieces.
Short answer to your question: Yes
Yes, it is the same. The 7.1 is not a version number but a designation for the surround sound, as the headphones simulate 7 normal and one bass channel instead of the 2 channels in stereo or 5.1 in other surround systems. But as I said, the surround sound in these headphones is only simulated, which works quite well, because otherwise you would need 8 speakers for 7.1 surround. Like almost all other headphones, these only have 2 speakers.
The G432 is a wired headset, which means that the headset can only be connected by cable.
On a PC, this is possible with a free USB port or 3.5 mm jack plug.
For consoles or mobile devices only with the 3.5 mm jack plug.
I hope this answer was helpful for you
