"Money is no object" - I think you have raised the question in the wrong forum then

I think for most here on these forums, money is an object!
Not exactly going to spend £300 - £700 on few different headsets to test them out!
I have always assumed buy the most expensive one, that has to be the best one, or what?
Pls do not get me wrong...I am not rich, it is just after some (hard) savings I am ready to invest in good headsets...
All the above mentioned models have a similar price....that is way I asked the question.
Not always the more expensive one is the better.
Thanks anyway.
