    Correct. A resistor load. So... perhaps, just maybe, your headphones have something to do with your perception of its sound? :wink:

    Well, if I have multiple devices I've used, and one sounds like the treble is glary, it's the device. So, it's never the device? So, you think all sounds flat if the graph look flat? Is that what you believe?

    I'm aware of all the theoretical stuff, multi-BA, impedance interactions, etc.. I've been through many devices over the years, and I know what I'm hearing.

    One Sabre device has 'artifacts' and one Sabre device doesn't, so its 'Sabre glare'? Maybe its just V40 glare? Maybe its reviewer bias? Who knows..?

    You can call it whatever you want. Expectation bias is thinking there's quad Sabres inside thinking there's some sort sound quality in this device, and steered into thinking so. I could care less if there's quad DAC is inside or whatever LG is advertising, it's all about what I'm hearing out of it.

    :) Sorry ..I don't think you deserve the title, 'SilverEars'. :)
    Comparing an LG V30 / 40 to Galaxy S8 is funny. (in sound) (the S8 is the worst sounding phone I've ever heard eg (I could only listen to an A&K XB10)
    The current price of the LG V40 at $ 4-500 is just right. Not an extremely good phone (2018). But its sound is better than any! 2019 models. If you don't like Sabre DAC sound, it's a matter of taste.

    I did not have time to read the whole thread so i don't know if this info has already been shared but for some reason the V40 enables the High Impedance Mode when it detects headphones above 30ohms while for the V30 it takes around 50ohms.

    First of all.
    Drop the hi-fi status app from the play store.
    This also indicates normal (below 50) / Aux (medium pre-gain) / Hig Gain (above 50).
    Same method as V10 :) Aux can be seen with a smooth 3.5 extension. HighGain has a 3.5 extension(ebay) and a 75 ohm impedance enhancer( ebay) combined. Phone switches to High, impedance enhance pulls out, (extender stays) Phone stays in High, plug in under 50 earphones .. enjoys :)

    It can happen from time to time that the phone detection is a bit undecided what to do.
    If you unplug the missinterpreted phone and plug it in again, the phone won't getting to him, right?

    Encountered this on the V30 too.

    I just tested my V40 with a resistor box. My unit switches to high-impedance mode at 48 Ohm.

    Gentlemen, I have been literally fighting to trick the High Impedance mode since I put my hands on the V10 years ago, I do now know all the possible solutions to do that.

    Now I have in front of me my LGV30, my LGV40, a pair of Marshal Mode iem (30ohms) a pair of House of Marley Smile (16ohm) and a pair of Pinnacle P1 (50ohms)

    I plug the MM into the LG V30 and does not trigger the 50Ω mode.
    I plug the MM into the LG V40 and DOES trigger the 50Ω mode.

    I plug the Marleys into the LG V30 and it triggers the Low impedance mode (generic audio device)
    I plug the Marleys into the LG V40 and it triggers the Low impedance mode (generic audio device)

    I plug the Pinnacle into the LG V30 and DOES trigger the 50Ω mode.
    I plug the Pinnacle into the LG V40 and DOES trigger the 50Ω mode.

    The results are inescapable, the V30 triggers the High impedance mode at 50ohms while the V40 triggers it at 30ohms. At least my model, European, TIM Carrier.

    I have a pair of Sony wh1000xm2 and they trigger the 50 ohm mode on the v40. I only discovered this after I got the HIFI Status(LG) app. (It does seem to depend on the order in which I connect the cables, and switch on the headphones, but I'm not 100% sure on that.) I understand that these Sony headphones are less than 50 ohms so this bears out what you guys are saying.
  12. Jorel21
    @Alabama your WH1000 are 46ohm so very close to the 50 ohm "officially" required from the V series smartphones to trigger the High Impedance. What i am saying is that for some reason the V40 (at least the one i own) triggers the High Impedance Mode already at 30 ohms.
    Saturday I will receive another IEM which is 32 ohm and i'll test it with both the V30 and V40.

    just when you think you can't love this phone anymore..

    recently picked up a pair of LCD-2 F, beautiful looking cans but didn't expect my existing amp to provide the right juice to hear the magic (~1.5W). nonetheless ODAC (JDS Labs stand-alone) + Gilmore Lite did an admirable job but sounded anemic and perhaps hollow. new DAC/amp is inevitable.

    the next test was replacing ODAC with our LG's Quad DAC and run that output to the headlamp. didn't even get that far cause just for lulz I plugged the LCDs directly into the V40... good lord, this device has NO right to sound so good on headphones that are (relatively) challenging to drive with entry level equipment.

    i suspect it's the DAC more than the amp cause Gilmore Lite is no pushover. FWIW, I can confirm that LG V40 can handle LCD-2 with class :)

    edit: at least the fazor edition which I understand are a bit easier to drive.

    I've just received a pair of Tin Hifi P1s and they are quite disappointing on the V40. I was expecting this to be the case on the basis of the various reviews I've read saying they need a lot of power to get the best out of them. However maybe not quite as bad. My brother has an amp he's going to let me try out to see if it improves things. However, would appreciate any portable amp recommendations for a V40 x P1 pairing. I have been checking out various threads on this point but can't see anything that jumps out.

    Edit: I've got them on AUX, changed the tips and ramped up the vol past where I would usually be comfortable and they sound much more immersive. Quite surprised at the difference. I'm going have the Fiio E11 in on Wednesday so looking forward to seeing what that brings.

    Sounds good.
    Next step is to take the V40 on HIM to get the best out of the p1.
    It'll be worth it.
