The charging case has an LED Display that shows the battery status of each individual earbud.
Even with the case closed, the display still shows so you can check your charge whenever needed.
When I first saw these earbuds, I thought they looked cheap, but I was wrong. I decided to purchase them for my 14 year old boy, and he loves them. He's had them longer than any other pair of headphones he's owned and I haven't heard a single complaint about them no longer working.
My work requires me to do a lot of conference calls from home. With 3 toddlers running around the house, this was a challenge until I purchased the K98 Earbuds. These earbuds provide the same audio quality as Apple's AirPods, at a quarter of the price. And the noise-cancellation? Amazing. I can now block out the noises coming from around the house so I can focus on work.
