Here I go again?? Actually you agreed with me, you didn't present an opposite opinion; however, I can see that you're going to follow me around and attempt to continue to argue with me after I already dropped things in the T1 thread. If you read the quote of mine you referenced you will clearly see that it states "Some of those that have reviewed the T1 have stated that they prefer its sound signature". You and Skylab were clearly two of those I was alluding to with that statement, so I already said you preferred the T1. Really not sure at all where you are getting this opinion is the opposite of what I posted business? Perhaps it's just a desire to bicker?
Also, build quality wise the T1s are by no means sturdier. They come with the same cheap style quality headband as their lower end. Nothing special really. Warranty means absolutely nothing when it comes to products like this. I've never once had to take advantage of a warranty on any product I've owned. True manufacturer defects are rarely present and a warranty, whether it's 5 years or not, will never cover user error and damage. If one knows how to properly handle their material items a warranty is pretty moot.
It's cute that you want to claim that the detail retrieval is equal between BOTH of them. It's common for one to want to make exaggerated claims in order to justify their expensive purchases, to prevent buyers remorse and all that. Forgive me but I'll continue to put more faith in the impressions from Gu Sensei, neptius, and Skylab when they clearly state otherwise.
With regards to warranty, obviously if Sennheiser felt the same confidence in their product, then I say stand behind it and give a 5 year warranty. Most defects fail early...called infant mortality failures. However as time goes on they do plateau, but after a number of years they do creep back up. This is called the "U" defect rate chart.
Please note that this is my last response to you...I will be blocking out your comments in future as they really offer very little.
