KZ aptX Bluetooth Upgrade Cable - vs. TRN BT3

Ever wish budget Bluetooth headphones had the same attention to sound quality as audiophile-friendly IEMs? Wish no more. Both KZ and TRN have replacement cables that bring Bluetooth functionality to any 2-pin or MMCX in-ear monitor headphone. But are they any good?

My recommendation: TRN BT3 + KZ ES4

KZ ES4: https://amzn.to/2IJfXXk
