The T1-E has better magnets and supposed biocell drivers. They have better extension on both the lows and highs as well as more bass impact. They are also more resolving and are said to have better details. The T1 are more balanced/neutral, but they are less refined and techincal. This all from descriptions about the product, and bhazards impressions, mochill's comments, and my knowledge base.
