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. ### ⭐⭐⭐⭐⭐ A good buy. Works as expected. *by on Reviewed in the United States 23 May 2021* This adapter works as expected, and the price is right.Note that the Osmo Action only has a mono audio track. If you plug a stereo mic into the port, it will be combined into a mono signal. This adapter will not fit with the OSMO Action port door attached. The door must be removed. If you are not familiar with how to do that, there are numerous videos online that show how to remove and reattach the door. It's easy once you see how it's done. Just ensure that you put the door somewhere safe, as it is small, very light weight, and will be easy to lose. Once the door is removed, if you need to use the cage that came with the OSMO Action, the adapter fits well and the cage does not obstruct the adapter's insertion or usage.I only tested this with one microphone. I used a lapel mic attached to a wireless body pack transmitter, and then plugged the wireless receiver into the 3.5 mm jack on the adapter using a 3.5mm TRS cable from the wireless receiver output. I spoke into the lapel mic as it is typically used, reading a paragraph from a book. The playback audio was clear, free of noise, and sounded full. The full sound of course will depend on the type and quality of microphone you use, and how far away it is from the sound it's trying to pick up. The further away the sound source, the more room or ambient sound will be recorded along with the source sound, which will make the overall sound more tinny and thin. Also note, as has been mentioned in reviews of this kind of adapter, that the USB charging pass-through only works if you supply power using a USB-A to USB-C cable. Using a USB-C to USB-C cable does not supply pass-thorough charging power.I would believe that this adapter will work with most microphones that have a TRS or TS 3.5 mm microphone jack that either can run from the limited power provided by the input jack, or that use their own internal battery for a power source. If you have a 3.5 mm TRRS mic jack, you may need to get a TRRS to TRS adapter, or short pigtail adapter to make it work. I am unsure as I don't have a TRRS mic to test it.To ensure that this or similar adapters work properly, you need to have a current OSMO Action firmware installed. This is easy to do and mostly automatic via the DJI Mimo app. If you have an older OSMO Aaction and have not updated the firmware, there is a chance that this adapter will not work until you update the camera firmware.Since I just received this today, I do not know what the longevity of this device will be. If it quits working or starts having issues, I'll update this reivew. ## Frequently Bought Together - 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) - YALLSAME Frame Case for DJI Osmo Action 1 Skeleton Housing Protective Shell Cage with Cold Shoe Mount Photography Vlog Accessories Kit for DJI Action 1 - LP Battery Charger Kit Compatible with DJI OSMO,3-Pack 1300mAh Replacement Battery and Intelligent 3-Channel USB Charger Kit for DJI OSMO Action Camera（NOT for Action 2/3/4） --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/414450244-jjc-dual-usb-c-3-5mm-mic-adapter-for-dji](https://www.desertcart.hk/products/414450244-jjc-dual-usb-c-3-5mm-mic-adapter-for-dji) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-20*
