You would short circuit the amps and it will take a bit. If it breaks the first or the five hundred time no one could say. It also could start sounding very bad if your unlucky.
I almost always use 2.5 with my er4sr or hd25 and I often know which one to use before I even turn es100 on so no worries for me I guess...
Ah, alright, so it is kind of like corrupting a usb key from not properly ejecting, only permanent, then?
Yeah, I have had rotten luck with it today. The led became solid green and the buttons were all un-responsive until I plugged it in.
Then the app wouldn't connect anymore even though it was connected to my phone. I had to jump through a bunch of hoops to change the settings on the ambient mode and unlock the 2.5mm to stick in my 3.5mm.
Luckily, it really does sound amazing! I've been using the Shanling M0 since launch, and while it sounded good with 24 bit files, it sounded average with everything else. Everything on the ES100 sounds amazing.
Thank you all for your help. I had just three more questions. First, if I lock it to 3.5mm in the app and want to use the 2.5mm plug with my DAP, do I have to go back on my phone and unlock it first? Does it remember the lock setting from the phone after I turn it off?
Second is that I hear stuttering at first when I connect and play a song. Is this doing any harm? I also notice a lot of stuttering if I connect it to my DAP and phone at the same time. Am I damaging the ES100 or my earphones? It just doesn't sound like typical bluetooth connection stuttering...
