You can if you order a Chinese splitter. All it does is split your lightning into two ports: the charging pins and all the other pins. Because the sound is sent digitally from your lighting port to the splitter, then digitally again to the lightning-to-3.5mm dongle you have no quality loss from a subpar splitter chip.
