JJC Dual USB-C 3.5mm Mic Adapter for DJI Osmo Action 1 (Only),Not Compatible with DJI Osmo Action 2 3 4,Audio Adapter Vlogging Accessories for OSMO Action 1 Camera (Only)

Original JJC product. It was imported item hence took some time in delivery. Quality is good. Charging as well as 3.5 socket are working just fine. Please note you must use TRS cable not TRRS. If not sure, do some research in advance.

If you are shopping for this specific adapter; you already know that the market (including Amazon) is flooded with fake versions of Cynova branded adapters. DJI web site says that; Cynova adapter is built for Osmo - but not necessarily licensed. You can also find web site of cy-nova (a very poor web site which you can't even find that adapter there!). No info on Cynova web site about having an exclusive license for adapter, which costs more than twice of what you'd pay for this JJC branded one. Then (if you start with that sloppy Cynova as authentic product); you only go down hill from there. Because when you search; you'll find all kind of imitation ones - with price ranging all over. If you check reviews (including Youtube videos); you'll see lots of problems (noisy audio, adapter not fitting/falling out, USB-C not charging thru adapter etc). Enter to JJC. They are a serious photography accessory manufacturer from Shenzen China (also hometown to both DJI and Cynova). Their adapter has a model name: AD-OA1 and properly identified on their decent web site. If you check my pics; this JJC adapter is a professionally packaged product. And unlike many average non-branded Chinese products (with only a paper sticker); this JJC adapter is proudly branded both on the product and all around on the packaging as well. How about the performance? It simply works perfect: -Mechanical fit is fine (it does not slide out as fake ones). -No added noise on the audio (tested with my Edutige ETM-001 microphone) -Camera charges fine through this adapter and USB-C. If you connect your Osmo to a Windows PC (thru this adapter); it's also recognized (so both data and charging works on USB-C port, thru this adapter). -Both microphone and USB-C port work at the same time. A general word of caution for charging your Osmo Action camera (apparently many people are not aware of this): USB-C port of your Osmo Action camera (I'm not even talking about this adapter here) does NOT support PD or QC protocols for charging. It only uses 5V fixed and does not negotiate higher voltages with the charger. How do I know that? One of my QC/PD capable wall chargers displays voltage and current drawn from it's both output ports (one QC and one PD). I connected my Osmo Action to both ports (with proper cables, of course). Osmo settles on default 5V at all times. It draws about 1A current. In general; a USB-C connector is only the physical side. A device can use USB-C connector : A) for regular USB data communication / slow charge and/or B) for receiving fast charge using QC protocol C) for receiving fast charge using PD protocol. So USB-C port on Osmo Action camera can only receive good-old 5V USB slow charging, as it doesn't have fast QC or PD capabilities. After all; it's just a small battery and Osmo did not invest in extra circuitry for fast charging which will both increase the cost and most importantly thermal buildup within that small camera body. But if you still want to charge your battery fast; you'll need to remove it and charge inside an QC capable external battery charger. Bottom line : if you need that mic adapter; only buy this JJC one. Paying more than twice to a supposedly authentic Cynova (even if you are sure you found one) won't add anything extra. This one perfectly works and is the most economical option (also happens to be the ONLY branded product).

Worked as designed. No issues.

本体内蔵のマイクが壊れて籠もった音しか撮れませんでしたが、これで復活できました。 水場での撮影では使えませんが、水場では映像専用、陸上では今まで通り収録できるようになりました。

This product is genuine and really work with dji osmo action
