Speaker imaging

There are reasons why things sound different without lights or glasses, etc., and they're real. Your conscious brain reacts to things automatically all the time and if you remove a stimulous like lighting or ambient noise you will hear differently...to a degree...I've found for years that late night listening has value because personal focus changes. There is a meditative state I can get to with my eyes closed that makes music fairly intense, as long as I don't open my eyes to find I've wound up handcuffed to a sink in a Cuban hotel room surrounded by aggressive spider monkeys...I hate that...

Another issue is the nose...it's rarely mentioned that some sound goes up your nose while listening and there has been very little research about where that sound ends up. Trapped in the sinus cavities? Does the lower midrange battle with the nose hairs? Can you recover the sound lost to the nostrils? Try listening with and without a large moustache, or simply stick earplugs in your nose when seriously listening to see what I mean...it is an issue requiring further research.

I think it's more of a nostril directivity issue more than nose volume. You need to keep the sound out of there...one idea is to knit micro sweaters to wrap around the nose hairs. That's just one idea, albeit a great one.
