Want to listen to an iPhone 7 and charge it simultaneously? That'll be £35

Charging while listening to music now requires an adapter - and things get really complicated if you want to plug into power while using old 3.5mm headphones

Apple's removal of the headphone socket on its latest iPhone 7 has had several knock-on effects, but one thing most people might not realise is that if you're using wired headphones with it, you can't charge it at the same time. Unless you buy a 35 adapter. Or a 49 dock.

The scrapping of the long-standing, universal 3.5mm phone connector, commonly known as the headphones jack, has already boosted sales of wireless headphones, which according to Apple is the way forward. It's also upset a lot of people, whose often high-priced cabled headphones now need an adapter to plug into the Lightning socket of the iPhone 7, should they buy one.
