Interesting question. From a technical standpoint, the answer would seem to be yes
. The anechoic room would seem to eliminate additions to the signal from acoustic sources.
The last time I heard a speaker playing in an anechoic room it sounded weird, but that was so long ago that I now have unanswered questions.
For example most speaker's low end response presumes some near-by boundaries which a true an anechoic chamber obviously lacks. The results can usually be expected to include significantly attenuated low end response, which in my mind qualifies as "sounding weird".
Listening to closed-ear headphones or IEMs is probably as close to anechoic listening as many are likely to get. Many people such as myself have adapted to headphone and IEM listening environments and are comfortable listening that way, but some people don't seem to be able to adapt.
When it comes to hearing electronic or lossy coding artifacts, headphones and IEMs seem to be exceptionally sensitive, although not everybody agrees.
I've been listening through headphones for about 50 years, so even if adaptation is slow, I've probably experienced it.
