Impedance adapter against headphone hissing? - Xiaomi Mi A1 Questions & Answers

Hello everyone, does anyone have experience with these impedance adapters? Do they successfully remove the hissing sound on the headphone jack?
Ifi Audio - IEMatch
Ifi Audio - Ear Buddy
Ultimate Ears - Buffer Jack
DUNU Impedance Adapters
Background: Headphones with higher impedance seem to experience less or no hissing (above 45-60 ohms). If you do not want to buy a new pair of headphones, in principle you can purchase an adapter that increases the impedance. Before I do so (they cost from $5-50 depending on the model), I wonder if anyone has had positive experience with this.

Hello,
I have the Creative EP630 in ear headphones. The hissing sound using the plain headphones is really unbearable (even clearly hearable on normal volume).
Thats why I bought the EarBuddy adapter. With the adapter the hissing is almost completely gone. I can still hear it very little when there is absolute silence, but it is definitalety at a lower or equal level compared to other smarthphones (and not anoying). The rest of the sound doesn't seem to be affected, except that it is at a lower volume (however I'm not an audiophile).
I would also recommend using to use the MI Sound Enhancer (Settings >> Sound >> Headphones & Audio Effects). For me the "General In-Ear" profile improves the sound a little bit more.

Hissing/static noise everytime G1 plays sound. Both speaker and headset. Just me?

I have a noise problem, I don't think it's quite the same as previously posted noise problems.
I get a hissinh/static noise from the phones speaker (on the back) and from headphones. It is only happening while the phone plays sound (and some seconds later). Every time I up or down the sound with the volume keys, there are noise coming out of the speaker for some seconds. Please report if you have the same issue, especially eith headphones.
I could live with the speaker-noise, it's not that big a deal.. What's worse is it is in the headphones. I have a quite low impedance set of in-ear plugs from creative (I am able to hear the hard drive spinning up in my old mp3-player, but no constant noise) Crap. I want to use the phone for music listening. Question is: software or hardware related? Using JF 1.51 ADP for the record
I hope it is hardware related - I bought mine off ebay, allthoug brand new and everything, I don't know how I would go about getting it fixed/a new one with no receipt. Shipping it back and forth to England isn't really tempting either.
It's not just you, it's piss-poor rf isolation on the audio outputs. Listening with bluetooth doesn't solve the issue either as bluetooth has its own noise.
Yeah, I have yet to listen to a decent pair of BT headsets.
So this is a known problem, and it's definitely a HW issue? The fact that it's only there when sound is played, and is also there with a headset (where shielding around connectors is not and should not be a problem at ALL) made me hope this was softwar related. Argh, what to do then? The sound quality despite this seemed prety decent, although a headache today prevents me from really listening to music and say for sure. Shame.
*Pondering refund options.*
Any chance of isolating around the connector and fixing this, if it is "airborne" caused noise, or will the noice enter the equation before the connector (cabling, sound chip)?
I will try with a relatively high impedance headset (sennheiser 555) and see if it is better there. But can't take them on the bus anyway. But a couple of Ωs could always be added somewhere along the cable and might do some good. Have to have the sound at the lowest levels with the in-ears. Maybe a software fix to lower the volume output will help? Or won't it, if RF noise is the cause?
red: I will buy this item and hope it helps. And will look into lowering the volume output when using headphones as well. Should be possible (atleast it usually is with tweaks in WinMo.)

Balance control?

I'm moderately deaf, and my left ear is worse than my right. Is there any way to get a "balance" control in software for when I use headphones?
G.
Maybe you can modify the cable of your headphones? Make the sound lower on one of the speakers.

Adjustable Mic gain?

Myself and a few others are in need of a way to adjust the Mic to speakerphone level while a headphone jack is plugged in.
I have my N1 plugged into my car stereo and the sound quality is great for navigation and phone calls but people cant hear me.
Engaging the speakerphone button boosts the Mic gain but switches audio output from headphones to the tiny rear speaker on the phone.
Is there a solution I have missed? Thanks.

[Tip] for spotify users/low audio output

My momentum in ears didn't get very loud so I tried disabling the normalize volume setting and this increased output on so far all of my music.
Didn't think the lower quality audio chip would be a problem but it might be a thing to consider if you use high impedance headphones, you might need to use an additional amp.

Bose SoundTrue--DAC sound quality

Has anyone used BOSE SoundTrue (one without the phone call/microphone option) with V20? I had interesting experience. When I played YouTube video (strong bass, loud beats, etc, etc) the first time around, there was hardly any difference in the quality w/wo DAC (in this instance, I kept turning on and off the DAC option during the video playback). I replayed the same video again, and this time, there was a clear difference of quality where the sound was lot more crisp and solid (when the DAC was on).
Has anyone had experiences
a) something similar but with different company head phones? (i.e. sound quality once good and not so good at other times with the same song/video)
b) something similar with SoundTrue? If so, do I need to get better earbuds? BOSE SoundTrue has been great overall so far for me in general
Sometimes I have a problem with the headphone plug on my high impedance headset. I've had to spin it around or replug it to get it to switch from being an external or normal device to high impedance one
