I ordered the Lightning version but heard from Alpha & Delta that only the type-C adapter uses ALC5685 and the Lightning ones uses Realtek ALC4040. They say difference is due to the fact that the iOS software restricts software decoding to 16 bit at the moment. Is this the case if so please update your description.

Hey, why does it state in the description that lightning with 3.5 would be +$1 but in fact it's +$3?

Do adapters like these and cables really improve sound quality? I’m either very skeptical or naive.

The makers say the output impedance is 32 Ohms. This is an atrocious number. Stick with in-house models from Apple or Samsung (the Apple one is actually surprisingly good).

Would this work with S20 Ultra? I bought a couple of adapters like this but they don't work with my phone.

32 ohms output impedance is a horrible design. Come back with something at 1 ohm and I'll believe it's a serious product.

Well in terms of functionality, it will be what you are looking for. Just remember to choose the 2.5mm output. In terms of sound, I would say that there is no coloration in our product so things will sound exactly the same as intended.

The specs on the page should indicate that the lighting version uses the older ALC4040 chip.

Is this item just for headphones or is a headset (with mic) supported too?

The 3.5mm ones will have mic support but the 2.5mm and 4.4mm ones will not. This applies to both the type c and lightning models. - Teo from Alpha & Delta
