BASN Bmasters are worth every penny imo. Way lighter than the KZ and come with enough different tips, there is no problem fitting any ear. Nice case included, so if you want to carry them...no prob. Another plus is that two sets of cables are included, one with mic, one without. Not being an audiophile I cannot give a concise breakdown on the sound, but I burned them in listening to Yuja Wang playing Rachmaninov and by the finale I was hearing a sh*t ton of instruments that I never heard before listening to this same recording with any other device. Pretty amazing for a low/mid-priced set of buds.
