Can someone try my idea to hear 1st crack better? I’m not ready to roast for a week or two.
You need: Android Device and Active Noise Cancellation headphones (I have a set of those made by Bose).
Using an android device, install “Sound Amplifier” (made by google, no ads).
Put the android device right next to the bullet with the app working. Listen through the headphones, and adjust the app settings. I think this should greatly reduce the Bullet’s fan and the exhaust fan noise.
