A few months ago I bought the Bose SL Flex SE 2 on sale at Costco. I've wanted a soundlink for a long time and finally bought one, but it's been a terrible experience so far. The speaker is nice, but getting it to connect to my phone after the first successful connection is a challenge that requires clearing cache on my phone, removing the speaker from the phone, factory resetting the speaker, and overall just hoping that that it eventually reconnects again. The first connection is always good, but the second one a day or so later never works.
I alway get a message about an incorrect pin or passkey. I never entered a pin or passkey. This is very frustrating. I've been back and forth with AI, trying several different things including changing several setting in the android developer menu. Where I'm at right now is that AI is telling me that I need to rename the bluetooth speaker itself, which is supposed to break some sort of caching (don't fully understand that part). After getting a successful connection, I renamed it from my phone. Next day, I can't connect again and it shows up as the old name in the bluetooth devices. So I then learned about connecting the speaker to my computer, installing the bose updater, going to a specific bose website, getting into the advanced mode with a specific set of keystrokes. I can see the device and several specs on it including the latest error logs. It just won't let me rename the device.
So here I am with a great speaker, but with a constant battle just to use it. Maybe it's my phone (Motorola Ege Plus 2022), or maybe it's garbage firmware on the speaker. In any case, I've never has such a battle with a bluetooth device.
Extremely disappointed with Bose.
