To display my art of whistling to Mp3 music I bought Lewinner699 - Great sounding! Lewinner L 699 Professional Karaoke Microphone Wireless Speaker Portable Bluetooth microphone for phone support record TF play|Microphones| - AliExpress
The only problem with that is that its noise reduction chops the music sound at low music volume levels. As soon the Mp3 music level increases the noise reduction stops chopping the music.
It's OK for singers, yet I need to lower the Mp3 music level so that my whistling is clearly heard. Now its music level is far too high and at a low music level its noise reduction chops and cuts the sound. I contacted Lewinner technical service, but they refuse to help me, fearing I try to copy their circuit.
One way I thought of, is inserting a resistor in the music path, which decreases the music power, but then allows increasing the music volume Pot (without increasing its loudness) so that it overrides the noise reduction.
Sadly, I can only take a photo of the circuit and carefully search for the music path emanating from the TF-card driver.
I have basic electronics hobby experience. All I need is a bit of guidance on how to search for the music path so that I don't destroy anything. I'll let you know how if I succeed.

Thank you justanalogue,
Apart from that problem, this thing is very compact and pretty useful. It's meant for singers; not for low music applications. I wished I could somehow locate the noise gate resistor.
To trace an audio signal I think I need to use a 0.1uF Cap and headphones. There must be somewhere a resistor near the DSP, which sets the noise gate level, and changing this resistor or bridging it with a small capacitor might do override the noise gate (?)
- I was also thinking of totally other ideas: such as adding a low-frequency noise to the music so that the (fixed) noise gate remains inactive. Any better ideas?
I like to use it with my art of whistling to good music. If the music is not too loud my whistling can my heard. Here's a sample (I recorded on my laptop) of what I'm doing: Box

I think I partly resolved my problem this way:
The Lewinner699 has got 108FM for music & Mic output. So I bought one of those FM-Modules, connected it to 2-inch Speakers and stuck it all into a flat plastic box, which I hang onto my neck.
I noticed that the FM-music output is luckily not controlled by the same noise gate and thus, bridges somewhat the gap created by the noise gate. The small speakers also favor my whistling.
So, in a way I'm glad gotten away with avoiding adding more gadgets, for I could have used the Lewinner699 only for whistling and a separate 20W Mp3 player. Yet, this way it's still "compact" enough.
