I got the EarFun Air Pro 4 as an early birthday gift and liked them at first, but about 2.5 months in the right earbud started making a high-pitched screech whenever any type of ANC was on. EarFun support walked me through troubleshooting and, when that didn’t fix it, immediately sent a replacement pair that arrived at my address in three days. I’m grateful for the quick, professional help, but disappointed the original ANC failed so soon.Edit: one month later noise cancelling stopped working on the new ones. I contacted Earfun support and they refunded the person who bought me the original ones.
