            Headphones came quickly. Sound quality, the microphone is good, comfortable. Very satisfied. The only negative is the problem with connecting two headphones, not convenient.

            The box was wrinkled, but everything was whole. Very easy control, figured out immediately. Very good, i have a little fall out of my ear. In general, excellent, long hold charge

            Great customer service

            I’ve bought about 2 different wireless earphones from Uiisii, One having bad connection issues which Uiisii customer service replaced for me. Always had good experiences with Uiisii and their products are great! Lost my 2nd earphones decided to pull a plug and get these because cmon AirPods are way overpriced and it’s the same as the wired just falls off the ear. And the price tag for this is unbeatable! Great product would purchase again in a heartbeat! Let’s see how these go.
