As long as these phones have a 3.5’ headphone jack, you have 1 channel 8-20 kHz ADC and two channel 8-48 kHZ DAC. That’s not I2C or SPI but it is helpful and us

As long as these phones have a 3.5’ headphone jack, you have 1 channel 8-20 kHz ADC and two channel 8-48 kHZ DAC. That’s not I2C or SPI but it is helpful and useful for many applications. The people at Square (payment app) can tell you all about it.
