Product code: Sony WF-1000XM4 good Wireless Noise Canceling In Ear Headphones Earbuds Set
Sony WF-1000XM4 earbuds tested and working. I have upgraded them to the latest firmware (2.0) which let's you connect to two Bluetooth devices at the same good time. Battery life on both earbuds as well as the case, are great! Any questions just ask. These are XM4's (not XM3's) it just wouldn't let me create the listing otherwise *.
