So, if the air is cool, then it will reduce the speed of sound. Simple as that! But at what degree is this noticeable at such short distance? I don't know, but it's certainly interesting to discuss
Slower speed of sound doesn't mean the frequency changes. As alexpea already pointed out, the only difference it makes is that the sound arrive quicker/slower. After that, the perceived sound is identical.

The speed of sound does change with atmospheric pressure..

The OP has inspired me to take a midnight walk with my SR-80's. I'm looking forward to a slightly increased soundstage as well as having the numbing cold refocus my concentration inwards.

Edit: I have only one thing to say: soundstage. This brings to light a new observation - that your visual cues must also corroborate with your audio cues. Simply closing your eyes or sitting back in a enclosed room with a very expensive setup will not let you get that final step in audio reproduction. In fact, I think sitting in the middle of a concert hall, with a recording of a symphony, will really give you a nice experience.

Mystery solved: Hershberger Reinforcement Curves - Wikipedia, the free encyclopedia

Due to the nature of sound wave propagation, environmental variables can dramatically change the perception of sound. For example, in environments with greater relative humidity, low frequency (less than 100 Hz) sound waves tend to be accentuated, while there is a marked attenuation of higher frequencies (greater than 7 kHz). Conversely, high frequency sound waves are perceived with greater accuity in temperatures less than 25 deg C.

I play the piano and I can relate alot to the OP.

My piano is placed quite near to the balcony. Everytime it rains, temperature drops, everyone silents down and the sound from the piano suddenly becomes transcendental.

I love it.

same goes to my headphones.

The changes in pressure from altitude and going outside vs. inside may have some effect. Isn't it possible that even as your blood pressure changes while you exercise that it could affect your hearing?

no wonder the cryogenic crowd are salivating at the mouth when they deep freeze all the audio materials they can lay their hands on.

seems they are onto something...

I have noticed the car speakers have pronounced highs when cold out. In the summer, bass is. I slide the moonroof cover back in the summer for better highs.

well, i noticed couple of times that my yuins in cold winter sounded unreal , sounstage was huge almost like in a rock concert (compared to a regular home use), and that in a noisy street !!! so i guessed maybe its just me, but it seems this is some kind of a common thing
