Why don't you listen to them and see if they sound good to you? Then decide what to do...
I know them well... my 14 year old son was obsessed with these headphones for months as they were all over the kind of tech web sites he reads. They look good and have all kinds of cool bluetooth features but when he actually purchased a pair and realized that all those cool features were not quite ready for prime time (guess a few firmware updates were required) he realized they just weren't worth the money.
Not sure if these comments help your predicament, but I used this as an opportunity to show my son what $299 buys if spent on sound quality as opposed to all the marketing crap that the Parrot Ziks specialize in.
