USED Huawei FreeBuds Pro 4 Earbuds Used for approximately 10 days from the date of this advertisement. The earbuds are like new, as is clear, and all their accessories are with them. Earbud specifications: Sound isolation for listening and microphone isolation for calls. "Meaning, if you call someone and you are in a noisy place, your voice reaches them and reduces the surrounding noise.
