Review on Wireless Bluetooth 5.0 Headphones: 20 Hours Playtime Earbuds with Charging Case - Stereo Earphone Cordless 🎧 Sport Headsets in-Ear Earphones with Built-in Mic for Smart Phones - Ideal for Work, Running, Travel, Gym by Robert Dingaling

It has an Apple Lightning connector for charging! That can't be legal! Not much is expected at this price point, just basic features. That also fails: The first set, the right side, doesn't hold any charge at all, it goes out immediately after undocking. Ordered a replacement and arrived in ONE DAY! The second set had an issue on the left: it charges but only lasts about a minute before telling me the battery is low. In a short time I had two sets on hand: although I take a good one from each set. Sharing and pairing was flawless - just slip them into the case and they're connected, no fiddling with the controls. But with what turned out to be a working kit, the original left side only held music at a very moderate volume for 40 minutes after a full charge. 3 hours applied. I'm happy with two hours. The battery goes from 100% to 80% in the first 20 seconds. The playback sound is only average, not outstanding, but typical and appropriate for this price range. The sound would be tolerable if it weren't for the battery problem. The sound from the mic is the worst I've ever experienced from a similar set, it's dull and distorted, like overload, but still not loud enough. There are several kits here for around ten bucks that hold a charge well and sound better, especially the mic. For the price I would leave it if it weren't for the battery issues. Unfortunately, the two sets I received are completely useless.
