I have just purchased my first Nothing product the Nothing Ear. First thing I did when setting up the buds was to install the firmware update so I can’t speak for previous versions but I must say I am very disappointed with their performance on this latest FW version. I am using them with an iPhone 15pro so that must be through AAC. The connection is unstable, I experience frequent stuttering and cutting out of the music. Also sometimes the pair just gets de-synced and one side is slightly lagging behind for a few seconds making the music sound absolutely horrific, after which comes a 1-2 second pause, then the music continues again synced in both ears. I experience these bugs several times daily, even tried returning the product to the retailer, which they refused due to hygiene reasons which is fair but now I’m stuck with a product that is very buggy and does not live up to my expectations at all. Only thing I can hope now is that these issues get fixed in a future FW update, so please fix it asap!
