As well as other features you would expect from modern earbuds like active noise cancellation and EQ controls, the Amped Buds support the magnetic Qi2 wireless charging standard

One of the more nifty things I saw at Mobile World Congress 2025 was HMD's nifty earbuds case. It has reverse wireless charging and even works with an iPhone.

Extra charge for your phone — or tons of power for your earbuds.

HMD has unveiled a new pair of earbuds, called Amped Buds, at MWC 2025 that offer a unique feature other earbud makers should copy.

HMD’s Amped Earbuds come with a charging case that can also wirelessly power up your phone. The 1,600mAh Qi2 case doubles as a power bank for iPhones, HMD’s Skyline, and other compatible phones. The case is thicker at 14mm and features a unique hinge system for storing and charging the buds.

The Amped Buds also come with active noise cancellation, environmental noise cancellation, and a dedicated equalizer through a smartphone app. The Mobile World Congress is an annual event that showcases the best from the smartphone world.
