I bought some oneplus buds z just under 2 years ago and was pleased they offered a 2 year warranty. When one of the buds stopped working I contacted the Oneplus support by email and got no response even though the automated response said thye will contact you within 48 hours. I called up the support and it turns out the warranty is only valid if you buy the product direct from Oneplus. So I will be throwing away my Oneplus buds along with any chance of buying from Oneplus again. . .
