amazon is listing the Single BA with the dynamic drive Hybrid you suggest at $150 +5 dollars for shipping (3rd party seller....) and I would suggest the Shure SE215 since it has a better value and probably way better SQ for the price ( I haven't tried or heard of the one your suggested so cant comment nor any reviews on amazon ). I loved the Shure SE215 at the price of $99.00 because the SQ is pretty great but I returned it because I didn't personally liked the thick cable
If you are going for a balanced armature I would only suggest one with at the very least 2 BA's inside the earphone with one of the preferably a Sub woofer
How would having 'at least 2 BA's' inside an earphone make it better than a single BA driver earphone with better SQ ?
