Review on Immerse in Deep Bass and Crystal-Clear Sound with Wireless ANC Earbuds Bluetooth 5.1 - True Wireless Headphones for Noise-Free Listening Experience by Christian Young

The sound quality is surprisingly good and the price is great. Earplugs are comfortable. One problem is that the Bluetooth connection announcement sounds very muffled and difficult to understand, making a bad first impression. It took me a minute to realize it was a muffled female voice saying "Bluetooth connected" in English but with a heavy foreign accent. The same applies to the declarations of the different modes "ANC" and "Transparency". I'm also not sure about the sound quality on phone calls. I'm hard of hearing but I've only tested it once so far and it may have been a problem with my friend's phone. Must test again and update later.
