"The T1s sounds very good. However, comparing to Q701 when plugging into my laptop directly, the T1 got destroyed."
The Beyerdynamic T1 is a 600 ohm headphone. It was not designed to be plugged directly into a laptop. It needs to be properly amplified. By contrast, the AKG Q701 has an impedance of only 62 ohms and can be driven by a laptop.
