My first pair of Bluetooth earbuds. Ear buds sound great. Hear through and phone microphone seem to pick up a lot of background noise. I have not bee able to charge the case hence the earbud batteries are flat. Have used them for about 4 hours, have spent much more time and effort trying to charge them. Working with Jabra support but time zone differences mean each attempt takes days. Currently waiting for next suggestion from Janda support. Wasnt looking to buy something that needed fixing.
