For correct level matching, you need to measure the voltage on the headphones playing a test tone, and match it within at most 0.1 dB or 1%. Setting the volume by ear is not enough.
Was you comparison sighted, by the way ?
My comparison was not volume matched by ear. It was done by a sound pressure meter with headphones(LCD2s) cup fully enclosed around the meter. I actually gave O2 around 1-2db more than Beta22, because I wanted O2 to win my ears over and save my money. It did not.
My comparison was sight by my wife, dogs and kids..... Seriously though, are you saying all audio impressions have to be done in your objective way? How many existing Headfi reviews were conducted that way (how many even bothered to use a db meter like I did)? So any review that was not done that way can not provide any useful information?
Ok, I give up. People, if you believe these people who have not even heard both Beta22 and O2 side by side, go ahead.
Search "beta 22" within this thread, and you will see that most if not all actual owners of Beta22 perceived a difference between Beta22 and O2. Feel free to not believe an actual owner's impression and believe those who SPECULATE based on specs and graphs. I hope you will enjoy your music more that way. And by the way, give your review in a subjective scientific manner or it is wrong.
