I have owned these WF-1000XM4 earbuds for quite some time. The charging case DOEScharge wirelessly. I routinely charge them on my Samsung Qi charger. Unfortunately, they work very well until they age a bit. In mine, the battery discharges rapidly, and Sony will not fix it nor allow discounted purchase of a replacement. A similar thing happened with my prior Sony WF-1000XM3 earbuds. Bad battery life, refusal to repair. I will NOT be buying another set of Sony earbuds; the …XM5’s are supposedly now available, and I don’t want to get burned 3 times.
