Review on Gray Wireless Earbuds Bluetooth 5.0 - True Waterproof TWS Earbuds, IPX7 In-Ear Headphones with Charging Case, Built-in Mic, Touch Control, 40 Hours Playtime by Kelley Zulkifli

DO NOT BUY THIS IF YOU WILL USE IT FOR CALLS! Doesn't work for calls. No one can hear me through the phone even if I speak directly into it. The only reason I bought it was so I could use it to make hands-free calls. It's useless for that. All the other reviews say they work so I bought these. But I've tried mine a few times and NOBODY can EVER hear me on it. I wasted my time looking at the reviews. Now I have to take extra time to send it back because it doesn't work as described. Extremely disappointed!
