I previously purchased this item in excellent used condition here. Huawei app connection confirmed working. ☆In my opinion, the sound quality is very good☆ Connection and operation are problem-free. I was using different ear tips and playing LDAC, and I felt that the separation of instruments was clear, with a high-quality sound and a lot of information, yet it wasn't tiring to listen to. I thought it was a very well-balanced earphone. I own multiple Freebuds Pro 3s and bought this as a sub, but I'm selling it to organize my equipment. Battery life in my environment was 100% to 87%~85% after 1 hour of listening with NC off, LDAC, and volume at 60% (photos 8 and 9), so I think it still has plenty of life left. The left and right earphone battery balance is also good. *This is a sale of the main unit only; there is no box or accessories. Everything in the photos is included. Please consider this item if you are satisfied with the condition as shown in the photos, as it is a used item. No returns. Huawei Freebuds Pro 3 LDAC
