I use the Audeze LCD-2C planar magnetic headphone (Chord Qutest Dac+Schiit Lyr 3 hybrid tube Amp) at home and the Campfire Andromeda with my phone and my laptop (Chord Mojo).
But I always want a proper True Wireless earphone that is decently audiophile grade, so when Noble Audio came out with the Falcon TWS, I jumped at the chance. Plus, it's really affordable.
In short, I think these sound great! When you get a proper seal and fit, which was kind of a challenge for me since my ears is slightly larger than the small, the audio quality is really good and the sound stage is excellent.
It took me a few attempts and approach to find the best fit for my ear that gives a tight seal, and unfortunately even though the Symbio Eartips by Mandarines provided a far superior sound and fit, it prevented the Falcon to sit properly in its case to charge. I had to settle with the stock tips.
The bass has good impact and slam, and surprising amount of bass extension without getting boomy or sloppy. There's no muddiness that spill over to the mids.
The mids is pretty full, but not I'd call velvety or lush. It's not recessed or too flat, though. There is presence and vocals are just slightly forward and has good energy.
The treble does have a bit of sibilance in some vocal and some instruments, but it's not fatiguing or brittle. I would call this a bright earphone.
It has an elevated bass, linear mids, and slightly elevated treble with harshness.
Detail is pretty darn good and sound stage is even better. The Falcon sounds larger than the it'd seem, and there's more staging side to side than front to back. Everything is slightly more forward and engaging if anything.
As for the buttons, if you just push in, it does stick in your ear a bit, which is annoying. I find that if I hold the top with my index and push with my thumb, the Falcon stay in place nicely. Functions are all responsive. These also pair easily and quickly every time I pop them off the case. Simple to use, just like the Airpods (but better looking and better musical performance).
My last issue with the Falcon is that it's slightly quiet. Even at full volume, it's not that loud compared to all the other IEMs and Bluetooth headphones I've used in the past.
In conclusion, the Falcon is a great buy with an engaging but clean sound, and it's very easy and convenient to use.
