Hahhaahaaa, You're literally killing me with this one ! But you're definitely right that I don't believe you.
Dont you see/understand these clear benefits?
Let's stop with your theories already and look at a real world A/B comparison.
One of the best selling Bluetooth headphones is the QuietComfort 35 which is the best selling wired QuietComfort 25 made wireless. The 35 is $50 more expensive, it weighs 20% more, it only has 20 hours of battery life, it has a non-replaceable battery.
Many things to read in this article, but this snippet sums things up nicely:
"In case you're wondering, the QC35 does sound a little better as a wired headphone. Despite Bose engineers' best efforts, you do lose a little something when using Bluetooth. With these types of powered headphones, there's plenty of digital processing going on and the trick is to try to get the headphone to sound as natural and clean as a corded headphone. That's really hard to do.
I sat around with Steve Guttenberg, who writes CNET's Audiophiliac column, and listened to several tracks -- in both wireless and corded modes. We both thought the QC35 was a tad bright (a little hot in the treble) and Steve made the comment that in Bluetooth mode, the headphone isn't entirely consistent, which is usually the case for Bluetooth headphones.
The meaty bass tightens up a bit when you're using it as a corded headphone and the clarity improves slightly. It's not a major difference, but there is a difference, and both Steve and I liked the headphone better as a corded active-noise canceling headphone. That said, Steve, who's an audio purist, is not a fan of active noise canceling or Bluetooth wireless."
