Ive never seen a pop up or anything saying high or low imoedance. Interesting to read that. It works great with every headphone ive tried though. Anywhere from 16 ohm to 64 ohm.
Only happens sometimes after plugging headphones in. You should see a small, thin blue popup about 2/3 down the screen saying the volume level has been modified. Think it might only happen when auto switching from normal to high. Tried but couldn't get a screen capture of it.
What I experienced so far was that there was no pop-up saying it realize the high load headphones. However, the effects can easily be seen. It will be much louder, cleaner, and pumping once turn on hi-if dac...vs....default snap-dragon. He could very well meant that the auto detection in the V10 pumped out so much power that it actually may damage the Z7 on max volume setting. Like I said before, z7 with 45-55 volume is ears blowing....and I didn't dare going max volume as it will bring deafness in a couple minutes. Therefore, he could verify that Z7 is hard to drive according to the auto detection behavior on the V10, and I don't doubt that. It has a very huge driverseven though the voice coil resistivity is 70-80, it is much harder than that to move such large diaphragm.....regardless, V10 drives it with authorities. I believe Z7 is one of the best full sized headphones for V10 in the mid to high-end audio equipment, and I believe V10 with Z7 will beats most of the mid tier DAP without problems at all.
So it is like if you hit a lottery, you want a mid tier dedicated player, and a phone ? V10 is the answer, also the price is so cheap and actually only a couple hundreds away from mid tier DAP which has ways less appeal and functions.
I agree. The Z7 seems perfect for the V10.
However, I found another quirk of the adaptive amp. I understand why LG made it that way: always on would kill the battery (like daps where we are lucky to get 10hrs use) so they made it turn off automatically once headphone is removed. The normal vs high power output is likely prevent damage.
Problem is, for my mk3, I tried switching to a cable with remote so I could control playback. Each time the V10 went to normal mode instead of high (explains why I got different results with my 61 ohm HD598). Seems it defaults to normal with any headphone using an in-line mic/remote (I tried a non-remote 4-pole cable to be sure it wasn't just the extra rings). I guess they assume no high-end or high impedance headphones use an in-line remote. So, I can't control playback on high impedance unless I navigate fully from the phone.
I don't have a remote cable for my Z7 though (was just about to order one for a D7100 on ebay too) so if anyone has one I'd appreciate if you could try it and post whether it shows normal or high. To see it you must go to main phone settings, tab over to sound and notifications, scroll down to hifi dac and touch it. The next screen (below) will show what mode it's in. I usually go back to the previous screen, unplug the headphones (dac turns off), then reconnect and recheck again to be sure.
