Apple Lightning to 3.5mm Audio Cable
The Apple Lightning to 3.5mm Audio Cable comes in one 1.2m length, black or white, at S$49, though Amazon.sg had black for S$40. I needed it because my Belkin equivalent wouldn't work on AirPods Max.

3.5mm audio cables, adapters, and headphone-jack dongles for keeping wired audio alive.
Belkin 3.5mm Audio Cable With Lightning Connector
The Belkin 3.5mm Audio Cable with Lightning Connector lets you connect an iPhone to any 3.5mm audio system without Bluetooth. MFi-certified, its DAC outputs high-resolution audio up to 48kHz/24-bit. It comes in black and white, in two lengths.
Apple Lightning to 3.5mm Headphone Jack Adapter
The Apple Lightning to 3.5mm Headphone Jack Adapter retails for S$14, though most authorised resellers were out of stock; I grabbed the last two from iStudio Paragon. The build feels fragile, with a thin, breakable cable.
iblazr – LED Flash For Smartphones
The iblazr is a compact LED flash that plugs into the 3.5mm audio jack of almost any device, not just smartphones. Measuring 27x32x9mm and weighing 10g, I bought mine in Hong Kong from Life Digital at ifc mall for HK$388.
Moshi 3.5mm Audio Jack Splitter
The Moshi 3.5mm Audio Jack Splitter, at S$20.90, offers something most splitters lack, even the pricey Belkin one, letting one of the two connected earphones support a microphone. A splitter lets two people share music from a single device.
McKAL Airplane Audio Adapter
I bought the McKAL Airplane Audio Adapter from the new Challenger at Bugis Junction for S$6.90, or S$5.90 with member's price. Now I can finally use my own earphones for in-flight entertainment, and keep watching 10 to 15 minutes longer.
