Which headphone adapter do I need?

When Apple moved away from the 3.5mm headphone jack with the iPhone 7 other manufacturers like Samsung and Google have followed suit. Now there are a plethora of different standards for smartphones while wired headphones and speakers mostly still use the 3.5mm jack. So if you want to plug your wired headphones into your smartphone or plug your phone into your car stereo, you need one of these headphone jack adapters. From the USB-C jack usually seen on android devices to the Lightning jack found on Apple products we’ve got the adapter for you.

Some computers and laptops have two separate jacks for headphone and microphone, splitting the audio and the microphone signal to two different inputs. Headsets are the same way, some are designed around a USB connection while others rely on a dual 3.5mm jack if your headset and computer don't match up then look to one of our adapters to get you connected. So you can work, listen or play seamlessly.

Can headphone adapters provide extra features?

What if you’ve got a set of Bluetooth headphones but your device isn’t Bluetooth capable? There is an adapter for that! These headphone adapters work by plugging into a USB or 3.5mm jack and providing a Bluetooth signal that your headphones can recognise. So you can enjoy your playlists without the annoyance of wires.

We also stock a range of headphone jack splitters. These effectively turn one headphone jack into two. So that you can plug two sets of headphones into one socket and share your music with friends! There are even adapters that enable simultaneous charging and listening. So you can plug your power cable and headphone cable in at the same time and never run low on battery.

Whatever your headphone adapter needs. We’ve got you covered. Thanks to our verified sellers the OnBuy selection features all the best brands from around the globe. From great value manufacturers all the way up to premium audio equipment specialist brands, we’ve got the headphone adapter that suits your needs. Shop now!

Frequently asked questions about headphone adapters

What are dual headphone adapters?

Dual headphone adapters, also known as audio jack splitters, allow two headphones to be connected through only one audio jack. They can be used to insert 3.5mm audio jack plugs into the headphone jack.

Headphone adapters aren't an important factor for sound quality necessarily. However, some can boost the existing sound quality, making the overall listening experience seem more enjoyable. 

How do I use an airline adapter?

Airlines use two-pin sockets on their planes and they're very easy to use. You just need to plug your headphones into the adapter. Then, the adapter should be plugged into the two-pin socket.

How do headphone jack adapters work?

Headphone jack adapters allow you to connect your headphones or any other audio devices to an external source that isn't compatible with standard headphone jacks. For example, a headphone jack adapter with a Lightning connector can be used for new generation iPhones, iPods and iPads. You just need to plug your adapter into the device, and the other end into your headphones.
