I bought Parrot Zik, Sony MDR-1RBT and Logitech UE9000's, tried them all side-by side for a month, returned the ones I didn't like.
Zik's look great and have a fantastic touch interface, but the battery life is extremely poor and the DSP way too heavy making the music sound synthetic, also they acoustically transmit loud footstep noise too much when walking.
Sony's had great battery life, very light, but no active noise cancellation and too much mid-range, they also have the habit to catch wind in the vents which makes a noise. If it wasn't for the oppressive mids, these were the best, despite the lack of sound cancellation.
The UE9000's destroyed both the Zik's and Sony's on sound quality, brining all types of music to life with a nice tight bass that's very present without being oppressive. They had a decent and non-intrusive active noise cancellation and the battery life was decent, but they are very heavy, and the controls could be more intuitive.
I stuck with the UE's for the sound...
