Somehow, I always manage to leave the house in the morning with fully charged headphones, but I rarely remember to charge and bring a power bank. It's not as though the former is essential and the latter nonessential -- I need both to get through any big day out.

The Amped Buds TWS earbuds, unveiled at FC Barcelona home Camp Nou, feature a charging case that doubles as a battery bank. The company also announced "Project Wildfire" with Drew Barrymore to promote digital wellness and healthier tech habits.

Many earbuds on the market feature wireless charging in the case. That's nothing new. However, I don't want to spare my precious phone battery to reverse wireless charge some earbuds. I'd rather have a functioning phone.

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.
