Apple has refreshed its iPod range for 2015. While iPod sales have fallen off a cliff in recent years, with most people now using their smartphone as an MP3 player, the iPod still has a dedicated following amongst exercise freaks and children who are too young to be given their own mobile phone.

Apple uncharacteristically leaked a shot of the new iPod range within an update to the iTunes software earlier this month, but now we have the full details on each new model. The iPod touch has had the signifcant revamp, as it now has one of Apple's 64-bit A8 chips and an 8-megapixel iSight camera. This is a long overdue upgrade, as the iPod touch hasn't received a hardware refresh since 2012. It will also be available in new colours, including space grey, blue, gold, pink and silver, and come in four storage sizes, including 16GB, 32GB, 64GB and 128GB, priced at £159, £199, £249 and £329 respectively.

The new iPod touch will also have Apple Music, which can be found in the Music app. Likewise, the A8 chip also comes with Apple's M8 motion coprocessor, which can be used to track your fitness with Apple's Health app. Of course, the iPod touch will receive a free upgrade to iOS 9 this autumn as well.

The iPod shuffle and nano, on the other hand, have only had a cosmetic change to introduce the aforementioned new colours, with no significant hardware upgrades in sight. You won't be able to access Apple Music on these products either, although this is hardly surprising.

The iPod was one of the products that helped transform Apple's financial fortunes at the start of the century, but the latest Apple annual earnings show that sales are down 48% year-on-year, with the segment now in an irreversible decline. Even finding the devices on the Apple website is a challenge, with the iPod no longer afforded a tab of its own at the top of the company's homepage.
