Pretty happy so far with the SR25. I gave it a full charge last Friday when I got home with it, been using it lightly since, and still have 25% battery.
I bought this primarily for the sound quality, and so far I'm very happy, especially with my (also new) CA Cascades.
However, maybe I'm just spoiled by 10+ years of iOS usage, but the UI and other 'quirks' of this device have got me scratching my head.
-I'm at my desk downstairs where my iPhone XS, iPad, MBP, and for that matter PS4 all seem to connect just fine to my WiFi. The SR25 shows a very low signal and drops off of WiFi from time to time. OK, so I can just go upstairs closer to the AP and it works better, but this is annoying.
-Bluetooth implementation is pretty crap on this thing, I mean when it scans devices it comes back with a list of MAC addresses??? Where are the device names, so I can choose my Shure BT1? Or any of the 3 other BT speakers I have? So far it's been a guessing game, and I haven't found the right one yet. While this isn't my primary use case for the device, and I'll of course use the wired Cascade Has 95% of the time anyway, it's still kind of annoying for a device that cost AUD1200.
I'm certainly not hating the SR25, but these kinds of things take the gloss off of what is otherwise a fine little device...
