Buying Guide
Connector type and headphone plug
Most wired headphones use a 3.5mm plug. The iPhone 16 has only USB-C, so you need a USB-C to 3.5mm adapter. If your headphones use Lightning, you need a Lightning-to-USB-C style converter instead. Check the plug on your headphones before you buy.
Good picks for this: Htrenc Type C Aux Audio Dongle Cable Cord, 2 Pack; USB C to Lightning Headphone Audio Adapter
Built-in DAC and audio quality
A digital-to-analog converter changes the digital signal into analog sound. Adapters with a documented DAC, like those listing 16-bit/48kHz support, can sound cleaner than basic passive dongles, though the gain depends on your headphones and your ears.
Good picks for this: JSAUX USB C to 3.5mm AUX Audio Adapter; USB C to 3.5mm Headphone Jack Adapter, 2 Pack (HiFi)
Microphone and call-control support
If you take calls on wired headphones, look for CTIA-standard support. Owners often report that CTIA-compatible adapters keep the in-line mic and play/pause or volume buttons working, while non-standard ones may not.
Good picks for this: JSAUX USB C to 3.5mm AUX Audio Adapter; Apple USB-C to 3.5 mm Headphone Jack Adapter
Charging pass-through
Some adapters let you charge the phone through the adapter while listening. This is useful on long trips, but charging speed depends on the charger, cable, and adapter support for Power Delivery. Confirm pass-through is listed before you rely on it.
Good picks for this: Type C to Aux Jack Dongle Cable Cord with PD Fast Charging; USB C to Lightning Headphone Audio Adapter
Size, fit and port strain
Adapters with a long body or a heavy DAC can put leverage on the iPhone’s port. A short, compact dongle reduces this strain. Keep the adapter close to the phone when carrying it and avoid pulling on the headphone cable at an angle.
Good picks for this: Htrenc Type C Aux Audio Dongle Cable Cord, 2 Pack; Apple USB-C to 3.5 mm Headphone Jack Adapter
Durability and care
Cable strain points and connector housings are where most adapters fail. Owners commonly report that keeping the adapter out of pockets with keys and avoiding sharp bends extends service life. Store it in a small pouch and avoid yanking the headphone plug.
Good picks for this: Apple USB-C to 3.5 mm Headphone Jack Adapter; USB C to 3.5mm Headphone Jack Adapter, 2 Pack (HiFi)
Multi-device use and spares
If you use wired headphones with several devices, a multi-pack gives you a spare and a second adapter for another phone, tablet, or laptop. This is a practical reason to choose a two-pack over a single unit.
Good picks for this: USB C to 3.5mm Headphone Jack Adapter, 2 Pack (HiFi); Htrenc Type C Aux Audio Dongle Cable Cord, 2 Pack
FAQ
Does the iPhone 16 need a special adapter for headphones?
Yes, if your headphones have a 3.5mm plug. The iPhone 16 has only a USB-C port and no headphone jack, so you need a USB-C to 3.5mm adapter. If your headphones have a Lightning plug, you need a different converter.
Will an adapter let me take calls and use volume buttons?
It can, if the adapter and headphones both follow the CTIA standard for the microphone and buttons. Owners often report that CTIA-compatible adapters keep call and volume controls working, but results vary by headphone model.
Can I charge my iPhone 16 while using a headphone adapter?
Some adapters list charging pass-through or Power Delivery support, so you can charge while listening. Not all do, so check the listing. Charging speed also depends on your power adapter and cable.
Do adapters with a DAC sound better?
A built-in DAC can produce a cleaner conversion from digital to analog, and some owners notice a difference, especially with higher-quality headphones. The gain is not guaranteed and depends on your headphones, your music, and your ears.
Why does my adapter sound quiet or crackle?
Common causes include a loose connection at the port, a worn cable, or dirt in the USB-C port. Try reseating the adapter, cleaning the port gently with a dry brush, and testing a different headphone plug. If the problem continues, the adapter may need replacing.
Is a two-pack worth it?
A two-pack is useful if you want a spare for a bag, car, or second device. It is less useful if you only need one adapter for a single phone and rarely misplace accessories.
Should I consult anyone about electrical safety when charging through an adapter?
Use a certified charger and a cable rated for your device. If you notice overheating, a burning smell, or damage, stop using the adapter and consult a qualified professional or the manufacturer before continuing.
Conclusion
For most iPhone 16 owners, the Htrenc two-pack is a dependable default for simple wired listening with a spare. Choose the Apple-made adapter if brand familiarity matters most, and the USB C to Lightning adapter if your headphones use Lightning. If you need charging while you listen, the PD fast-charging dongle is the practical pick, and the JSAUX adapter suits listeners who want a DAC and working call controls. The two-pack HiFi option works well for sharing across devices.
