HT18 Wireless TWS Earphone Bluetooth 5.0 Headphone 3D Stereo Earbuds Black

OverviewLenovo’s new TWS headphones are earmuffs, so they do not hang out of your ears, while they are In-ear with silicone tips in 3 different sizes to find the ones that best fit your ear. Both headsets have a Bluetooth 5.0 antenna, and a 40mAh battery that gives them 4 hours of use, with a touch panel on each that you can use to control the Playback of music and calls. The Drivers are 8mm, with the sensitivity playing around 100dB and the frequency range from 20-20Khz. As always I have no idea what these numbers will say. Their carrying and charging case, in addition to the slots for the two headphones, has a screen with an indication of its battery level, which reaches 1000W, and can charge 10-11 times each headset! The case itself is charged via MicroUSB.
