Intro

Hi all,

My name is Plamen, and I’m from Bulgaria. I’m new to the world of audio electronics, and this is my first attempt at solving such a technical challenge. I’m currently working on a project to enhance the audio output for headphones. My setup involves a Type-C to 3.5 mm jack audio adapter connected to an Android device. The issue I’m facing is that the chip in the adapter doesn’t supply enough power to properly drive the headphones, leading to very low audio volume, even when set to maximum.

I’ve tested this setup with various headphone models, including the OMWCO1, and encountered similar problems across the board. Interestingly, swapping headphones sometimes results in interruptions and strange crackling noises. I’ve also experimented with an Xmart-branded audio adapter, dismantling it in an effort to identify the chip used inside so I could order a replacement or find a more powerful alternative from electronics suppliers. Unfortunately, I haven’t had much luck so far.

I’m looking for an external chip to act as a headphone amplifier that meets the following requirements:

  • Provides sufficient amplification for clear, powerful sound.
  • Maintains compatibility with Android devices via USB Type-C.
  • Operates efficiently without excessive heat generation or high power consumption.
If anyone has suggestions for specific amplifier chips, resources, or general advice for a beginner, I’d be incredibly grateful. This has been a challenging but exciting journey, and I’m eager to learn more and resolve this issue.

Thank you for your help!
