  Probably the biggest challenge of this project is finding a phone with a headphone jack ;)

  <i>We all know that to achieve the best sounding hardware, you&apos;ll need to gold-plate everything. The connector, the wires, the PCB, the insulators.</i><br>/s

  After 4 years of engineering some of my basic doubts got cleared😂 thanks for the video🙌

  I keep being surprised how simple most electronics are. For the longest time I had this block in my head, telling me to not even try understanding.

  Imagine walking into the plane with that plugged in

  greatscott: And just like that you can make an audio amplifier.<br>Everyone else: &nbsp; &nbsp; &nbsp; :0

  When you started comparing the headphone audio I was expecting Scarlet Fire to play :-D

  Lovely! Will steal the design and build a higher voltage one for my 400 OHm headphones<br>Edit: I&apos;ve done it! Adjusted the resistors to match the higher voltage and current required by my AKG 340 and it sounds unreal! Way better than it has any right to. Can be powered for hours on end with just a small 3s lipo as the power consumption is so low. I could also boost the 5V USB power from the phone up to 12, but I fear it would add noise...<br>Mods I did are: increase current to 30mA, adjust the bias voltage divider to work correctly at 12v (2.2k + 22k) and replace the bc337 with two bc238 (they were what I had lying around, as a bonus they have a Gain product of 250)<br><br>Edit2: been using it for days, it&apos;s downright amazing! So much so, that I&apos;ve ordered all the necessary parts to build a proper one, with integrated battery + charger, and isolated 24V boost converter. I think I&apos;ll 3D print a cute case for it to make it pocketable and make it a daily carry gadget. I don&apos;t really care that it&apos;s not power-efficient either, since it&apos;ll be pushing 200mW per channel at most...

  Scott, you really make &quot;complicated&quot; things simple. It&apos;s education and entertainment as well. Stay tuned ;-)
