I can confirm that the UTWS5 connects to my phone while it is inside the case. I have already reported this in previous, recent, posts here. For example, I am listening to music with my FiiO BTR7 or my Qudelix 5K, and the UTWS5 is inside its closed case. Then, then lights light up and the music stops playing on my phone. I check in my Bluetooth Settings and I see the UTWS5, connected.
When it comes to EQ, I never use it, but I definitely believe all the people who report that they lose their EQ settings.
Finally, with multipoint, it is the first time I have used it. I have 2 devices, my phone and my laptop, and I have 2 pairs of the UTWS5. Before the 1.5 firmware, I had one UTWS5 permanently and exclusively paired to my phone and the other UTWS5 to my laptop. After manually installing the 1.5 firmware, I decided to test it. So, I paired both of my UTWS5 with both of my devices. It does not work properly. It reconnects to the wrong device. Whenever I take a pair out of the case, I can hear "Connected" and right after, "Disconnected". Very confusing. So, I reset it back to one pair of the UTWS5 with one device.
And yes, I have factory-reset both of them, unpaired and repaired them, etc
Looking forward to a new firmware, as well.
