that's a shame to hear you've so much trouble because of where you live. over here the temperature is always fine enough to have zero problems with a blurry screen. and yeah the sony vr earbuds are not very good, solution was buying sennheiser stereo 'over ear' headphones. my brain upscales the low resolution of PSVR to an extend where i don't recognize anymore that it's just half '1080p/eye'
