Hey,
I bought new R-15PM, they sound great and work good.
I've noticed weird delay on the last day using them (maybe it was always and just ignored it).
Is it normal to have a little delay after the speakers are idle for a few seconds? I can't even hear the start of the sound (Like Windows prompt or error sound), just the end of it.
Edit:
Forgot to mention, I'm using them on my PC through USB, although it happens with bluetooth too.
