Hi Avikalpa, thanks! The choice between those two should be sound based, in my opinion. The KZ ZSN has a more active bass, well supporting electronic and popular music genres. The bass of the T2 is more laidback — some find it lacking 'oomph' to be uplifting. The T2 has a more clear, vocal and mid centric sound that does deliver some minor details better though. Both of them are great — but if you listen to pop, dance or hiphop a lot, I think the ZSN will suit you better.
