Review on Linklike True Wireless Earbuds & in-Ear Headphones with Mic, Bluetooth 5.0, Stereo Deep Bass, Waterproof 36H Touch Control for Workout Sport/USB-C Charging/Mono & Twin Mode by Bridget Robinson

I have stress tested this device and I hope the feedback can help others. I have had other products from this manufacturer but this is their first wireless kit and I am very impressed. Presentation and packaging are excellent, small. The case is useful, has LEDs that show the charge (the others I've used don't, and there's nothing worse than having to charge and it's dead). The magnets holding both pairs in the case are strong, the blocks won't fall out even if the case is shaken vigorously. The lid is also durable. Bluetooth connects to Apple and Android devices VERY quickly, with Apple being the fastest. When watching YouTube, even with long playback times, there is no lag between what you hear and what is played. The average line of sight is 26 feet, auto pairing when falling down is very fast. Playtime on each earbud in my testing ranges from 4.5 to 6 hours, which would be 9 to 12 hours if you use one at a time. They're closer to the ear canal than other devices like the Apple in-ear headphones, which I like. Other blocks I had fell out no matter what rubber insert I used. I can really shake my head and they stay in shape. Sound quality is on par with their V9 and 10 models, with clear highs and plenty of bass. I am very happy with them. Customer service was very helpful, so I would recommend them to some of my friends who use expensive Apple headphones.
