The dongle market was born due to the removal of the 3.5 mm jack, but its dominant purpose is probably to provide users with the cheapest and highest quality audio which the big corporations have not provided us with, at least in terms of iPhones and Windows PCs if not Android phones (thanks to Qualcomm's WHS chips).

The problem is that even if 24/48 PCM is good enough for us, 24/48 limited silicon chips may not be. So we can listen to 24/48 PCM only, but we still want 32 bit codecs to be in every iPhone and Windows PC.

Audio enthusiast who wants to save their budget?
  • Try MDR-ZX110 of Sony with EQ.
  • Apple's (98dB SINAD / 113dB SNR) or Meizu's USB-C to 3.5mm dongle, or Tempotec SHDP with a USB micro B to A cable.
  • Meizu's USB-C achieves a balance between potential quality and range of supported formats beyond 24/48 PCM.
