An example would be Westone's new adventure line of iems. Westone isn't telling anyone that they are better than the w4 or es5 or W3 or UM3, etc. The newer and lower cost Shure SE215 isn't marketed as better than the 535.
The Re-400 sells at a lower price point than the previously sold RE-272, so yes, it is obviously surprising that HifiMan is saying the re-400 is better.
So, you've been proven wrong, let's move on to something more on-topic.
