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.

Bought these to see if it got rid of the white noise coming from my Fosi K5 Pro, and needless top say yes it did. 80-ohm seemed to work just fine for my 32-ohm FiiO JT1s, but for lower impedance headphones you might want to go lower like 75, 50, or 32-ohm.

I bought this mainly to see if it would help alleviate the issues I was having with the Steam Deck OLED's 3.5mm headphone jack. With sensitive in-ear monitors, there's a very audible noisefloor. This gets rid of that entirely. It doesn't seem to play suuuper nice with the Deck sometimes, but that isn't really a fault of the product. The only reason I docked a star is that I wish there was a 30Ohm version; the 80Ohm takes quite a bit of volume away, which is fine for me, but I think a 30Ohm would be better overall.

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.

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!

I bought these to counter the white noise I was experiencing when using my low impedance (16 ohms) earbuds with my gaming PC that was built with much higher impedance headphones (up to 600 ohm) in mind. Before using these, I heard a constant white noise in the background, and the headphone were deafeningly loud at low volume. I'm pleased to say both the 80 ohm and 220 ohm eliminated the white noise issue! Since I have both, I mainly use the 220 ohm plug as it helps keep the headphone volume from being loud at low volumes. Without the adapter, anything about 8/100 volume was deafening, but with the 220 ohm adapter, I find I can go as high as 22 ish without blowing out my ear drums. I was curious as to how close the advertised impedance for each plug was to the actual product received, so I popped out my multimeter and was pleasantly surprised to learn both adapters added about 80 and 220 ohms of impedance, respectively. Fantasic product, fantastic price. Best of all, I get to keep using the same earbud brand I love with my laptop.

As advertised

This item did what I hoped for a few weeks, but then suddenly the left audio channel stopped working. The adapter is completely worthless now!Both ears of the headphones (FIIO FH3s) sound balanced without the adapter, so I know it is not their issue.I only used the adapter indoors without any strong temperature swings or significant shocks applied. Do not buy this product if you want a lasting solution...
