The Elite 65t earbuds worked fine prior to the latest, October 2019, update. To be honest, my phone's battery is suffering the most due to the latest updates, which I have mentioned above. The left earbud had a horrible time syncing with the update but now it works. However, my iPhone battery is draining so rapidly that I deleted the Jabra Sound+ app just to have enough battery life to make it through the day. But get this, this happens even when the earbuds are not being used!!! Prior to the update, my phone's battery would drop to 78% every day!!! Since the update was installed, my phone's battery drops to 39% by 5:00PM; this NEVER happened, as stated above, before the update was installed. I will now try to re-download JabraSound . I hope this corrects the problem. Regarding sound: I wish they had more depth: the treble levels are stronger than the bass levels. Therefore, melodic music and classical music have strong highs but the depth of the bass, when EQ'ed, becomes a muffled distorted addition to the track. Overall, I enjoy the product but I truly miss the Klipsch and Bose sound I enjoyed when my phone accepted headphones; now I can only use Bluetooth headphones with my new iPhone.
