Hello,
I am looking forward to buying a decent headphone. The headphone's impedance is 47 Ohms. Usually, the lower the impedance, the less the trouble of powering it properly. Obviously, 47 Ohms in above the average impedance of earphones. So can someone here with a set of headphones with impedance close to 47 Ohms try it with the HAM2 and see if it gets properly powered.
Thanks.
I own Sennheiser HD 598, and even though the large connector requires an adapter to fit into the small headphone port of the phone, I did try it, and found the max volume to be just 20% shy of where I'd like my louder music to be. These headphones supposedly are 50ohms.

Does anyone have any idea what amount of ohms the headphone jack is pushing out? I'm getting a terrible hissing sound using my Sennheiser CX-300's which I have a feeling is due to an impedance mismatch. The Senn's are rated at 16 ohms.
I use a Philips SHN2500 Noise Cancelling Headphones Earphones 32 Ohm and sounds much better, remember this are Noise Cancelling and also helps.
So I was looking at different headphones and they range from 32ohm all the way upto 48ohm, then there are headphones with 100mW etc. I don't know much about these values in terms of headphones and how good a smartphone can support, in terms of current/impedence.
Any ideas how this actually works? Does the sound get lost if the phone doesn't support higher amounts of current.
I've been doing searches for the answer and can't find anything. I have a pair of Sony mdr-v6's. The output isn't really loud and has very little bottom end. I don't listen to bass head music either. I suspect there is an impedance mismatch. If you have an answer, could you provide a link to back it up? In the car, plugged into the aux in jack, I have loads of bass on a stock system.
I just checked and the imp of the v6 is 63 ohms. I am guessing the phone is closer to 1k ohms.
It's easy to force high impedance mode.
I've got a set of headphones with a detachable 1/8" jack at both ends, but you can use a splitter and an extra 1/8" double male plug cable as well.
I use the 1/8" cable and connect my v20 to another cell phone or tablet headphone jack. It immediately goes into high impedance. I unplug only the end going into the other phone and plug that end into my headphones. As long as the cable stays plugged into the v20 it stays in high impedance mode
If your headphones don't have a detachable cable, it'll still work with a splitter and a cable that has male 1/8" plugs at both ends.
Using the splitter, plug your splitter into the v20. Use the double 1/8" jack cable to connect the splitter to a phone or tablet. Once it's in high impedance mode, unplug the cable from both ends and connect your headphones to the splitter. Don't remove the splitter plug from the v20. As long as the splitter stays plugged, you'll be in high impedance mode and get more power into your headphones
Ok...what is the use of high impedance?

its just wasted a time, and change nothing on everything you hear. look, high impedance automatically triggered only if you put headphone with 50 ohm above. you know why? because regular phone or music player only could deliver impedance with range 15-30ohm. while lg v20 like any other DAP with external amplifier could support from 50-600 ohm. even with 250 ohm headphone if you put on regular phone it would only run on 30 ohm max. and same goes to your phone, even with your v20 or any DAP player which support 50ohm impedance above, if you connect to low impedance headphone it would only run on your max headphone impendance. its not something you could force to work.

Bro I agree with you. I have used 60ohms headphones and 45ohms headphones with my Lg V20. With 50hms and above, we can see "high impedance headphones connected" in settings.but nothing improved in sound quality. So doing force high impedance is unnecessary.

check your audio files first, make sure you have lossless audio like flac or dsd. for flac i recomended using song with 24bit/96khz. if you playing with stock lg music player you'll see there is "hifi" icon on the selected song. join audiophile comunity for more reference. and for headphones , well.. there are many type, some headphone have flat bass, more vocal, etc. choose one which suits you and the music you played. from what i got while browsing on auido/video community, there are 3 main requirements for best audio experience:
1. good drivers aka player like DAP/AMP or our beloved LGv20 which support impedance above 50 ohm
2. lossless audio files like flac, dsd/dsf which support hifi system
3. good headphone with high impedance that has many feature depends on your need. some people love high bass, while other prefer clear vocals, etc
lg v20 is a good drivers, its not the best but its good if you dont wanna spend another 150-250$ on music player with dedicated amplifiers.
High Impedance Workaround
I was thinking the same thing on an easy workaround, so I bought a $3 splitter, plugged in my AKG headphones which pulls up high impedance, then plugged the B&O earbuds. (that came with my V20)Then unplugged the AKG's and it remained in high impedance mode. Doing that, if you turn the volume up higher than 75%, you'll probably pop an ear drum. It gets waaay loud and clean!

Why not just use my mod and forget about extra cables?
NVM.. Just read no root. Sorry folks.

I never said it improved quality. I understand how DACs and amps work.
The reason for high impedance mode.... If you have headphones with less than the 50ohm threshold, high impedance mode increases power output from the amp. The result.... On low impedance headphones you get more power which means higher volume output.
I have a set of V-moda Crossfade LP cans that are less than 50ohm. On the regular power level, max volume of 75 still lacks a couple decibels for my preference. When I trip high impedance mode I am able to reach a higher volume level and I usually don't need to go higher than 60.

Exactly... Higher volume output. I didn't say it improved quality, as others are arguing.

Look at my last post.....
Triggering high impedance mode and then connecting low impedance headphones will give you more amp power which equals higher volumes. Does nothing about increasing quality just higher volume threshold. But only if you trigger high impedance and THEN connect LOW impedance headphones
This mod worked with a splitter in my v20. Thanks @Sid 6.7. wow listening to low impedance headphones at high power is a fun. Great workaround.
DUNU 200ohm adapter with KZ ZS3 headphone is decreasing sound. I just got the DUNU 200 ohm impedance adapter but after I connect it to the mobile and then KZ ZS3 headphone sound is very small though it is showing now high impedance mode. Please help me out. even I tried another normal headphone, it's the same. Without the adapter, it was okay with normal mode. But it should trigger the high impedance mode with an adapter, right?

200 ohms is over kill. You only need anything over 50 ohms.

i brought the following Connector for my LG V30 plus, it is only reducing the volume that means reducing the Noise actually. i brought 75 ohms connector to trigger the HIM on my LG, but not happening. What should i do? any suggestion plz help me out. is there any option i should enable?

This solution, of course, I know but want to use my in-ear old earphones with full sound. There is a forum in XDA where many say it works for them. which adapters works like charm?

Seriously, that is not really a solution... High impedance headphones simply mean they need more power to drive them, hence the DAC provides more channels to support the gear. If you want more power to your lower impedance gear, LG should have provided a way to enable channels upon demand. They didn't, because it can be a pitfall (see below). Sometimes, 32 to 60 ohm gear really gain from the 25% increase of kicking in the second channel, as opposed to higher impedance which will just eat up that power and not give more oomph.
The DAC increase triggers around 75 ohm or while in Aux mode... My technique for non-root phones is to add an 3.5mm extension, plug in a high impedance adapter/headphones (75 ohm+), unplug adapter, plug in earphones in extension. There's the double-stack extensions (Plug in two in a row to trigger Aux mode), but I haven't had much success with this, worked only sporadically.
However, I strongly recommend simply rooting and flashing a DAC enabler mod. It's much easier to deal with... If most of your gear is under 75 ohm, that second channel will provide 25% more power. Only thing is: Very sensitive gear might not like more power. So be careful. I've known people with gear lower than 32 ohm blow their earpiece with a V30 at high impedance mode.
If you wanna test out triggering different DAC levels, download Hi-Fi status off the play store. It'll pop up a toast notification telling you in which mode you are as you trigger the modes.
**edit** if ever you want a 75 ohm adapter, I have one I'm not using... Depends where you live, I could send it your way.

Also, it's normal that your 200 ohm adapter decreases the sound quality of your gear if you plug in the adapter and then plug in your IEM's in it... Think of the impedance adapter as adding a bunch of ping pong balls in a corridor... When you walk through it, it'll be much longer to get across. Your 200 ohm impedance adapter is like adding basketballs in this corridor instead of ping pong balls. The adapter gobbles up most of the extra power given by the DAC, so your gear gets none of it.

I think I should root it. I have ordered Sennheiser HD570 with over 65-75 ohm impedance. Let me check it first. I also have hifi status app. hope it will help me. thanks.

I got Sennheiser hd570 with 64ohm. It shows high impedance...but still not much drive from dac...it has same output as normal mobile..why??sound is better as it is better headphone but loudness is not there.
