Sony’s ECM-AX10 smartphone mic is live at $249 — the first mic certified for YouTube’s Eclipsa Audio standard, and built to record spatial audio directly into Android and iOS phones via USB-C. It ships with four omnidirectional capsules and three recording modes: Ambisonics (for YouTube), binaural (headphone-optimized 3D audio that works everywhere), and stereo. Weight: 24 grams. Pre-orders are open on Amazon, Sony’s site, and other retailers, no India price or launch date is listed in the reporting. The mic does not connect to cameras or computers. It’s smartphone-only. No mention of compatibility with iPhone 18 Pro or Galaxy S27 Ultra. Just USB-C smartphones, full stop. Eclipsa Audio isn’t a Sony standard. It’s a new YouTube certification, and the ECM-AX10 is its first hardware partner. That means if you record in Ambisonics mode, YouTube promises accurate spatial playback, no guesswork, no re-encoding. For everyone else? Binaural mode delivers depth and directionality even on Instagram or TikTok, where spatial metadata gets stripped. This isn’t a headphone product. It’s not a camera accessory. It’s a mic for people who film on phones and refuse to settle for tinny, mono, phone-mic audio. Especially now that YouTube has made spatial audio native, not niche. Pre-orders started today. Shipments follow.
