Frequently asked questions

What is Qi and MagSafe wireless charging? Collapsed link

Qi (pronounced chee) is one of the most popular standards for wireless charging. Wireless charging technology lets you charge your device over very short distances, without the need for cables or wires. No need to worry about plugging and unplugging each time, or untangling your messy wires, just pop your device on the charging pad or charging stand and away you go.

Qi is supported by most major brands including Apple, Huawei, LG, Samsung and Sony, so the majority of the latest phones and tablets will support wireless charging. Check your device tech spec to see if you can take advantage of wireless charging, then take a look at our range of wireless chargers.

MagSafe charging was developed by Apple, and is another way of wirelessly charging your device. The smart technology behind MagSafe allows for fully optimised charging, and provides a faster wireless charging up to 15W. You can shop the MagSafe Wireless Charger right here at O2.

What are the different types of Wireless Earphones? Collapsed link

Wireless headphones let you listen to music from your phone, tablet, laptop or mp3 player, without needing to plug them in. They can be split into three different categories:

Wireless earphones (connected via a neckband) -These have a wire connecting each earphone, designed to sit around your neck. They're perfect for running, giving you the freedom of wireless headphones, while knowing they’re safely secured.

Wireless over-ear headphones -Here you have your classic over-ear headphones, just without the wire. They look the same as the wired ones and give you the same benefits too, just without the fuss of wires.

True wireless earbuds -No wires, no cables, just the buds. Each earbud fits snugly in your ear and uses advanced Bluetooth technology, so your sound quality is still as crisp and sharp as ever. See our whole range of wireless headphones and earphones
