Thank you! Definitely helps in understanding how and why things are working a bit bitter. I did come across some of that info in the app, but my device is neither android or iOS--the WM1A uses Sony's own concoction for an OS... and when it streams BT, there is no more control of localized volume (what you are describing as source volume, I believe), and instead the volume buttons control the destination BT device. Just unfortunately not with the ES100. So, while I can quickly shuffle through songs on the player, any volume changes I need to dig around and find the tiny buttons on the ES100, often below layers of clothes/lab coats, etc. Just a pain in the butt, and was hoping there was a workaround, lol.
Duh, I completely glossed over that part of your post, tho in theory everything said still kinda applies... I can see why it would be a hassle if you're keeping the ES100 under winter clothes (tho for general use a dab of nail polish on one button can help locate them by feel).
The app is a workaround on Android phones but obviously not an option for you, although if you *are* carrying an Android phone in addition to the Sony player I think you could connect it to the ES100 for volume control and setting configuration only but *not* audio (don't pair it as an audio device).
