Hi, has anybody listened to the v20 on 600 ohm headphones?. Is the phone able to drive such high impedance headphones properly, is the volume Loud and clear? Thank you
If it isn't able to, try Hi-Fi Quad DAC
You need to know the sensitivity of the headphones, not just the impedance to really know for sure if they will get to a listenable volume. Without knowing more it's impossible to say. It's definitely not putting out enough power to get any 600 ohm headphone to it's full potential, even if volume is decent

Hello,
I was wondering if anyone knew what the output impedance of the Desire Z is? Or if someone with a voltmeter could maybe test it? The only source i've managed to find online was some other random forum post which cites 64ohms which just seems way to high for a mobile device.
I'm planning on buying a pair of low impedance headphones and am trying to decide if I'll need to buy an amplifier.
Thanks

the lower the impedance of your headphones, the less power is needed to drive them
I have a normal multimeter, so I cant get the impedance with accruacy.
In my case I read alot on mp3 players and audio cards in them. on headfi.com forums I found some frequency graphics and the htc desire worth it. Its not a cowon player but its pretty good. way better than a iphone.
So I decided to bought audiotechnica ath-m50 studio closed cans headphones. they are always in the top 10 lists of audiophile forums.
They are 38 ohms impedance headphone, and its pretty impressive on the DZ. I can't barely see any difference on a real amp like yamaha or audioresearch one.
on audiophile forums lot say that youll need a amp, buy with poweramp app its just allright.
Just had a go at measuring the output impedance of my Desire Z.
R Load = 19.9 ohm resistor
V = 171.3mV
V load = 76.7mV
Zo = 24.5 ohms
So output impedance is quite high, ideally use headphones with impedance of 300 ohms or above, low impedance headphones will work but will draw more current and won't sound as manufacturer intended but may well sound fine for day to day use.
My Sony broadcast headphones are 32 ohm whereas my Beyer DT100's are 400 ohm so a much better match for the DZ, both play loud, the DT's therefore are more efficient at converting input power into sound pressure.
measured again with 180 ohm load
Zo = 24.9 ohms
Guys I need your valuable opinion about the audio dac on this for NORMAL earphones like RHA s500. does it feel lot different as of compared to other phones on normal earphones or do we need High impedance headphone ?
Am in dilemma of purchase decision

Getting fed better audio should benefit most decent headphones. Of course the higher quality headphones will see the most benefit and take full advantage of the V20's audio capabilities. You don't need high impedance to take advantage of the quad DACs capabilities. It just delivers more "juice" to higher impedance headphones that require more power to drive. Some specific lower impedance headphones may do better if you could manually turn on the high output mode, my Audeze iSine 10s for example, but in general it will be fine for most earphone out there.
Just tested my Axon 7 (also a with a high quality DAC/AMP on board) vs My LG G5 (standard built in audio) with some cheap but pretty good sounding earphone ($10 to $15 KZ ZST ). I can sounds cleaner and voices are a little "sweeter". It more noticeable with my more expensive gear.
If you're into audio the V20 or Axon 7 are the phones to get, but there should be other reason to select a phone as well. Unless you really really desire superior audio, I wouldn't make my buying decision based solely on that.
I can hear a difference. It clearer sounding and vocals are a bit sweater. If you not big into audio it may be a bit subtle, at least at first.
I will be receiving my LG G6 asia version next week. In order to take advantage of the Quad DAC, may I know earphones or head phones I should get ??
I had similar problem. I've started \ found those threads. Maybe it will help you.

Just forget all that DAC nonsense. Its still not clear if the High Impedance mode just makes the phone louder or triggers all DAC Channels. And its not sure how the DAC works. But one thing, i dislike the Quad DAC, it doesn't sound atmospheric and nice to me. Its very analytic and boring for normal people. If you plug in Earphones with "normal" bass, you will be dissapointed completely, the DAC cancels out every bit of Deep bass. I bought a USB DAC (Zorloo Zuperdac) and i prefer it a thousand times to the Quad DAC. And its also louder.

Hello, this is not so much P9 lite firmware related, but I was wondering if anyone knows how well it can drive headphones of slightly higher impedance than the usual earphones. I'm thinking of buying headphones with 35 ohms impedance (ATH-M40x) but I want to make sure that I won't need an amp to drive them... So I'll appreciate any help if anyone knows.
Well, to answer my own question, in case someone might be interested, it can drive them alright; they do not lack volume, but you might find yourself trying to get them to sound louder if you're listening in a noisy environment, like a bus, as the isolation is not quite like that of an IEM.
I've had my LG G6+ (H870DSU) for a few hours now, but I think something might be wrong with the quad DAC. It's enabled, the icon is there in the status bar, but my IEMs pick a lot of static noise with any player app. This would've been normal with virtually any other audio source - I have very sensitive Shure SE535 IEMs - but from what I've read on Reddit, and particularly Head-Fi, the quad DAC should be dead silent, even with the most demanding IEMs and regardless of impedance.
For reference, I've used my IEMs so far with a Fiio X5 II and they don't hiss with it.
I don't get hiss or noise. Maybe your phone is faulty?

What IEMs/headphones do you use?

The B&O earphones that came with it, and Audio Technica ATH M30
the ground on the headphone socket is known to be a bit iffy.
The contact may be noisy?
Probably not this but worth a comment.
I have H870DS and there is no noise in silence at all.
