Typically that’s over Bluetooth, is there any specific need for AirPlay? If not - Anker Roav SmartCharge F0 Bluetooth FM Transmitter for Car, Audio Adapter and Receiver, Hands-Free Calling, MP3 Car Charger with 2 USB Ports, PowerIQ, and AUX Output (No Dedicated App) https://www.amazon.com/dp/B07GJ7DHMP/ref=cm_sw_r_cp_api_i_2RxPEbTBPJM1Y
Pretty much pair and go. Non-airplay means it works with any bluetooth device, not just Apple devices.
Have you considered the Fiio M6 digital audio player. It is the only DAC I know of that has an airplay receiver. Uses a high quality Sabre ESS dac so the audio quality is very, very good (Sound stage, dynamic range and all other audiophile goodness). It’s Bluetooth receiver is also the best I ever used and is almost close to wired quality. Available on Amazon if you wanna check it out (Paid £135 for mine).
