The right audio adapter for every device
USB-C, Lightning, or 3.5mm — which adapter or cable you need depends entirely on the port your phone has and the device you are connecting it to. Here is the complete map.
Three cable families, five products. Every wired audio connection you will encounter — from aircraft armrest to car stereo to laptop jack — covered in one collection.
- iPhone 15 and later (USB-C): USB-C to 3.5mm adapter (dongle) or USB-C to 3.5mm cable. Both convert the iPhone's digital USB-C output to analogue 3.5mm audio.
- iPhone 7 to iPhone 14 (Lightning): Lightning to 3.5mm adapter (dongle) or Lightning to 3.5mm cable. Both work with any 3.5mm headphone, car stereo, or speaker.
- Laptop, tablet, or older phone with a 3.5mm port: 3.5mm to 3.5mm aux cable. Universal wired connection for car stereos, aircraft, and any 3.5mm speaker.
- All Gibutech audio cables use gold-plated connectors and braided nylon jackets for consistent signal quality and long-term durability.
In 2016, Apple removed the 3.5mm headphone jack from the iPhone. Manufacturers of Android phones followed. Today, most phones use either USB-C or Lightning for audio output — yet most cars, aircraft, speakers and headphones still use 3.5mm. An audio adapter closes that gap. Getting the right one is a matter of knowing which port your phone has and what you are connecting it to.

Quick check: which iPhone port do you have?
Look at the bottom of your iPhone. A single oval port with rounded edges = USB-C (iPhone 15 and later). A slightly wider port with a flat bottom and curved sides = Lightning (iPhone 7 through iPhone 14).

A USB-C port outputs digital audio. Converting that to analogue for a 3.5mm headphone requires a DAC (Digital-to-Analogue Converter) chip inside the adapter. A quality DAC chip minimises signal noise and preserves the full audio frequency range. The Gibutech USB-C to 3.5mm adapter includes a DAC chip that reduces transmission losses — the difference between clear, full-range audio and thin, noisy output you might get from an unbranded alternative.

When do I need a 3.5mm to 3.5mm aux cable?
If your phone, laptop or tablet has a 3.5mm headphone jack, you can connect directly to any 3.5mm input without an adapter. The 3.5mm to 3.5mm aux cable is the universal connection for three scenarios:
- Car stereo: from your phone's 3.5mm jack to the car's aux-in port. Zero Bluetooth pairing, zero latency.
- Aircraft: from any 3.5mm headphones to the armrest entertainment jack. The only audio option for in-flight entertainment screens.
- Speakers and monitors: from laptop or tablet to any 3.5mm speaker or studio monitor for wired playback with no Bluetooth compression.

One adapter. Every wired audio connection solved.
The right audio adapter is a tiny, permanent solution to a recurring problem. Carry the correct adapter for your phone port and you will never miss wired audio on a flight, in a car, or through a speaker you cannot pair via Bluetooth. The Gibutech range covers every combination — USB-C, Lightning, and 3.5mm — with gold-plated connectors and braided construction built to last.
