I have the original Oladance through their Kickstarter campaign; the sound quality is simply amazing but the fitment behind the ears is not 100% , I hope this has been solved in the newer versions. Also, Oladance are on Kickstarter now for the Sports version (comes to about 200 AUD including shipping when you get the super early bird)
