Review on 🎧 COUMI ANC-860 Bluetooth Earphones: Wireless Earbuds with Active Noise Cancelling, 6 Mics, Deep Bass, 41Hrs Playtime, IPX7 Waterproof, USB-C Quick Charging Case, Smart Touch Control by Ben Karlen

It might not be great, but it's a reasonable price range. The sound quality generally lacks resolution. The low-pitched sound is a bit fuzzy but sounds very good, and the high-pitched sound is a bit unsatisfactory. The middle section is moderately balanced. In general, it is suitable for pop music. The active noise cancellation clearly works, but does not sufficiently filter out low-pitched sounds. Sometimes when a door closes or a car rumbles, it can amplify a little. It's good at blocking people's speech.
