thanks, I have ZS3 as backup and using now, but ZST fitted me better comfortwise. Just wanted to know if there was something new and better for purchase.

Hi, I am looking for KZ ZST replacement or should I go again for them? Left earbud died after a few months (4-5 months of using), so if I go for them again, I will have a spare part for future (lets just hope that the left earbud doesnt die again lol). Is there a better choice in the same price...
