FAAEAL Conductor Earphone Impedance Plug 80 220 ohm Noise Cancelling Adapter 3.5mm Jack Professional Reduce Noise Filter Plug (80 Ohm)

TL;DR: Yes, these two adapters do “trick” LG VXX phones into high impendence mode. Strangely, the LG V20 and LG V30 are only tricked by the 220ohm adapter. The LG V40 can be tricked with both the 80ohm and 220ohm adapter.Setup ChainBefore even touching your phone, create your Frankenstein cable by plugging the IEM/headphone cable into one of the ohm adapters (depending on your model of LG phone as stated above) and then plug the ohm adapter into a 3.5mm female to 3.5mm male adapter (here’s what I use for my phones: https://www.amazon.com/gp/product/B07V1DQTLY/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1). Finally, plug in your cable monster to your LG phone; this will trigger high impedance mode. At this point, remove the ohm adapter from the cable chain so you are left with your IEM/headphone cable plugged into the 3.5mm female adapter. I tested this method on a V20, a V30, and a V40 with great success. I included a picture of the Frankenstein cable completed and one broken into sections so you can see the proper order.Side NotesA. DO NOT plug in the adapters one at a time into your phone; the LG audio Gods will punish you for your insolence and you will be forced to listen to mediocre amplification for the rest of your days.B. The LG V20 is cool and will tell you, on the “Hi-Fi Quad DAC” screen, if you are in fact in high-impedance mode. If you did not plug everything in correctly, you will get either “Normal Impedance” or “Aux Input” descriptors. For some inexplicable reason, the LG V30 nor the LG V40 tell you the impedance mode on the DAC screen, but you can make an extra purchase (for a dollar) of the “Hi-Fi Status (LG)” app from the Google Play store, which lets you know what you are working with. This is the tax you pay to be a meddling audiophile.C. With great power comes great responsibility. If you are using some low-end cans/buds that can be driven by a potato, some string, and a battery, you really do not need these adapters. Sure, you will get more volume, but it’s kind of like putting a V8 in a Prius. Your music will likely sound distorted and the hiss can be unbearable. On the other hand, if you have an obsession with vintage cans or hard-to-drive planar monsters that make you look like Princess Leia, and for some reason want to use your mobile phone as your DAC/amplifier (because why not?), then these adapters are clutch. The adapters create much more headroom and you can now make your ears bleed from hard-to-drive IEMs/headphones that were either maxed out or quiet in “Normal Impendence” mode on the phone. I do think music sounds “better” (clearer, more spacious, and better dynamic range) with the adapters, but that is completely subjective and likely just from the additional volume.D. If you are checking this product out to actually use it as a “Noise Cancelling Adapter” or “Noise Filter Plug” per the product title, I suggest getting the 80ohm only. Like other reviewers, I have some sensitive IEMs that work well for gaming, but have the Slytherin house music playing in the background while I am trying to wreck some fools on Xbox. The adapter works well to quiet the hiss while not dulling the audio enough to make it useless; I might suggest adding one of these controller adapters to help you play with the sound and your game/chat mix (https://www.amazon.com/Turtle-Beach-Headset-Controller-Superhuman-Hearing/dp/B00PWRYKDE/ref=sr_1_3?crid=1LIWOKKP783RI&keywords=turtle+beach+controller+adapter&qid=1649215568&s=electronics&sprefix=turtle+beach+controller+adapter%2Celectronics%2C63&sr=1-3).E. Bonus LG VXX Comparison: the LGV40 is arguably the best of the bunch; it possesses the most EQ options within the DAC screen: Equalizer, Sound Preset, Digital Filter, and simulated DTS:X 3D Surround, which, surprisingly, is pretty effective, especially for classical, acoustic, and classic rock. The LG V30 gives you Sound Preset and a Digital Filter option, while the LG V20 (the old man of the group) gives you no special options. All of them allow you to manually turn the quad DAC off and play with left/right balance. The V20 has an ESS Sabre ES9218 by B&O (sometimes LG) and the LG V30/V40 use the ESS Sabre ES9218P (V30 is tuned by B&O and the V40 is tuned by Meridian). Sound is subjective, but to my ears, the V20 has an “analogue” sound that has a deeper low end, forward/“present” mids, and somewhat “grainy” treble. The V30 is the “most polite” of them all and has a neutral sound across the bass, mids, and treble; it gives you what the music gives you. The V40, even without all of its EQ options, is the most spacious sounding and has a slight focus on the upper mids and treble (“sparkly” but not sibilant); bass is there when it needs to be but will improve with EQ. Typing those descriptions made me want to vomit a little, but those are somewhat accepted terms in the audio club to describe sound (…can you taste color, too, bro?). It’s somewhat a recent topic (as of Android 10’s introduction), but the LG V50 and V60 allegedly no longer have the ability to play DSD files and no longer properly decode MQA; the LG V60 does have a slightly updated DAC: ESS Sabre ES9219. I figure if you have made your audiophile dive deep enough to be looking up an adapter for your now discontinued phone, which you are probably just using as a DAP, you might be curious about the rest of the line-up. Obligatory Soapbox Moment: download the USB Audio Player Pro app for any model and unlock some awesome, audiophile-grade sound.P.S. Shout out to FAAEAL for making an affordable product for a niche group of audiophiles and gamers.

I bought this because I got new iem’s and they had a static noise when plugged in, the 80 ohm one worked perfect and the static noise was gone, i’d say if you don’t know if you need these you probably don’t. But if you need them they definitely work!

The short version: these little adapters will alter the sound of your headphones. It's fun to play with as a deliberate effect on high impedance headphones, but it's not advised if you're trying to use this for other reasons, like forcing high gain mode on certain amplifiers. The adapters themselves are well made and do what they say they do without problems.These little inline pads are basically just two series resistors (one for each channel), the net effect of which is to raise the output impedance as seen by your headphone and the headphone impedance as seen by the amplifier (the circuit behind the headphone jack). The effect of this is to create a resistor divider between the pad and the headphone driver, lowering the voltage as seen by the driver and dissipating some energy in the form of heat in the pad resistor.On dynamic driver headphones (aka almost all headphones except certain audiophile and studio headphones), the impedance of the headphone driver will vary by frequency, so the effect of this voltage change also varies by frequency. Typically dynamic drivers will have an impedance peak in the mid-bass around 100Hz, and this effect will amplify those frequencies somewhat relative to the rest of the frequency response of your headphones. It's relative because these adapters will make the sound quieter all around, but the amount by which it does differs. For example, on a pair of Koss Porta-Pros, there's a pronounced impedance peak at around 95Hz. At that frequency, the adapter will attenuate the sound by 3.5dB. At 1KHz, the adapter will attenuate by 7.5dB. Once you readjust your volume, it'll seem like there's a 4dB boost to the mid-bass.So, it's fun to play with, and if you want more bass on your headphones you might be thinking it's a good idea. However, there are two major downsides to note: 100Hz isn't true bass, and making that mid-bass louder will make everything sound boomy but won't give you any more slam or rumble. The second downside is that it also reduces the damping factor of the amplifier, which means that the amplifier can't control the motion of the driver as well. This effect will make everything sound a little looser and fuzzier, which is probably not what you're after.On high-impedance audiophile and studio headphones like the Sennheiser HD 650, the effect is a lot more subtle, especially if you're using the 80 ohm pad. On the Sennheisers, the 100Hz peak is reduced by 2dB where the mids are reduced by 1.5dB. This is because the relative resistance of the headphone driver is higher and its impedance peak is relatively much lower. With such a small effect, it's fun to play with this as a slight tweak to the sound, and it can bring a little bit of the sound of a tube amp to a solid-state amplifier.I also don't recommend using this to try to trick an amplifier into high gain mode. On dynamic driver headphones you'll suffer all the disadvantages given above. With planar magnetic headphones, which are usually very low impedance, the frequency response won't change, but you'll suffer a different problem. Adding the resistor in line doesn't change how much power your headphones need. It actually increases the total amount of power the amplifier needs to deliver, and now the majority of that will be burned off in heat in the resistor. Since planars tend to be fairly power hungry, you may find that after turning up the volume or gain to compensate for the added resistance, your amplifier is just plain running out of power.As an example, the Hifiman Edition XS has an impedance of 18 ohms, so it will be attenuated almost 15dB by the 80 ohm pad. You can get the Edition XS to a pretty darned loud volume with just 1 volt of output, or 55mW. With the 80 ohm pad, you'll need about 5.5V to produce the same volume, and that will require 300mW. Most low-powered devices like phones or laptops will run out of power at 250mW or less. The effect will be to make everything sound blunted, smeary, or distorted. Dynamic driver headphones will suffer this too, but to a lesser degree since their impedance is higher and their sensitivity is usually higher as well.

I got this for my 5th gen iPod classic (video). The iPod was making an annoying static sound with headphones unless I used very expensive headphones. Sometimes I just wanna use my IEMs and this allows me to do that without that aggravating sound. There's still *some* static, but it's very low and is only noticeable during quiet parts. Super fast and cheap fix!

Using to put my LG V60 Quad DAC in Hi-Impedance mode to use with HiFiMan headphones and others that have low impedance. I bought this two pack (80 and 220 Ohm) as it wasn't much more money, just to be on the safe side. Both adapters work equally well. I just use the 80 Ohm and it works great.I plug it in as follows:1. Phone <--3.5mm extension dongle <--impedance adapter <--headphones2. After V60 confirms high impedance device, leaving the extension dongle in phone, remove theimpedance adapter (middle man) and re-plug the headphones to the extension dongle.Now you have this:Phone <--3.5mm extension dongle <--headphonesThe phone stays in Hi-Impedance mode and you remove the volume attenuating factor of theimpedance adapter. Having the V60 in Hi-Impedance mode gives more volume and impact.Recommended.
