If you are drilling all the way through to the other side and the mic is in the "target room" may work out okay.

Often referred to as a "leak detector". You can also buy a recording module for it to easily record audio. Amazon prices are jacked up vs. Aliexpress thanks to their seller fees.

I bought an HY929 from Aliexpress because it was so cheap - and the sound quality was surprisingly good. At least equal to the NAD-FX3 by Nikkei Acoustics, and for a lot less money. But like the NAD-FX3, the HY929 I bought quickly developed some kind of fault where the sound quality failed completely, so now it's useless. It might have been a dodgy unit, but for the cheap price they are going for on Aliexpress, it might be worth a try if you don't mind risking $20.

My best purchase for clandestine listening in the last few years has been the Metal Marshmallow black version (high gain). Not as sensitive as a high end dedicated listen through wall device (those are around $1k+), and with a bit more noise - but the MM is still decent, if in close proximity to the target in the building. And also - very very reliable. The guy who makes the Metal Marshmallow seems to know his craft. There's a new one called the Metal Marshmallow Pro, but I haven't tried that. But, you will need additional equipment to plug the Marshmallow into - an audio interface and ideally a DAW to record and apply filtering, so a laptop would be required for mobile sessions. It does mean carrying a bunch of equipment and cables around.

I have owned a Sun Mechatronics F-999R which I imported from Japan in 2009. Sadly I had to sell it a few years later to raise some money. It was an outstanding device which seems impossible to buy these days. The reviews for the newer consumer devices from Sun Mechatronics in Japan seem poor.

And there's a load of other random Chinese devices on the market. Just search Leak Detector on Aliexpress and keep looking, you'll find all kinds of gadgets and fake Sun Mechatronics devices, if you're willing to risk $100-200.
