Qualcomm Hopes USB-C DAC Dongle Will Alleviate Headphone Woes
2006 Called, It Wants Its Pop-Port Back!
Missing the point
Having to buy and carry around another thing to connect, which can be lost and/or damage.
The alternate is to replace a perfectly good set of headphones you already have
Deal with the quality drop and/or battery drain issues with Bluetooth
Having to use the USB port for the headphones means not being able to charge the phone
Or have a headphone port with DAC built into the phone
