Boya BY-K4 USB-C to 3.5mm TRS Female Audio Adapter Cable (6cm)

Picture this: you have just bought a high-quality shotgun microphone to film a vibrant street food vlog in Old Delhi, only to realise your modern Android smartphone no longer has a headphone jack. This frustrating mismatch is exactly where the Boya BY-K4 USB-C to 3.5mm TRS Adapter comes to the rescue. It bridges the gap between traditional camera equipment and mobile devices, allowing creators to capture professional sound directly into their smartphones without complicated setups.

The technical architecture of this accessory ensures your audio remains pristine. Built with a digital converter supporting 24-bit/48kHz resolution, it translates the analogue signal into a pure digital feed, eliminating the hiss often introduced by cheap dongles. The ultra-compact 2.4-inch length means it stays completely out of the way while you film. As a dedicated Type-C microphone converter, the female port is specifically wired to accept camera microphones rather than standard smartphone headsets.

When shooting outdoors across India, reliability is non-negotiable. Whether you are battling the intense coastal humidity in Mumbai or the fine dust of the Rajasthani desert, this adapter’s robust shielding holds up exceptionally well. The snug fit of the USB-C connector prevents accidental audio dropouts when moving quickly in crowded spaces, ensuring you never lose a crucial soundbite during a bustling festival shoot.

Our Pooja Electronics Camera Expert Team has put this cable through extensive field tests. What genuinely impressed our team in real use is the flawless, zero-latency audio transfer that syncs perfectly with video. Buyers should note one functional limitation: it strictly supports TRS inputs, so TRRS lavalier mics require an extra patch cable. We highly recommend this Boya BY-K4 USB-C to 3.5mm TRS Adapter for mobile filmmakers wanting guaranteed audio fidelity, and buying from our store ensures you receive genuine, warranty-backed gear.
