This is like just asking "what is the best car".
Without context, question is meaningless e.g. do you need an integrated microphone, independent volune control, full ear coverage, bluetooth, gaming, use,, music use, budget range. But from shop or online etc.
Firstly, this is a software forum so you would only get random responses. Also being in OZ, you may not have the same range of supply as other countries.
Really self help i.e. searching for web reviews is more likely to give you a more meaningful response.
