Glad to hear the review was useful Saiyajin. Thought it would be an interesting head to head test.
My understanding is the underlying technology is very similar (if not he same), so its incredible that the sound signature is so different.
We are expecting new stock of the Sleek Audio SA6 tomorrow. We've been waiting some time for this stock.
One addition to this review is that both earphones benefit from fitting
Comply Foam ear tips. The bass response becomes tighter and stronger on the SA6, the noise isolation is better and in both cases they are even more comfortable.
It would be really interesting to hear your comments, whatever earphones you decide on.
