A set of wireless lavalier microphones branded Retekess. The model is TG103.
There are several versions available. This one is the top-tier set: two microphones, two receivers, and a charging case for all that goodness. There’s also a cheaper version with just one mic and one receiver, no case.
The box contains only the manual and a USB Type-C charging cable. That’s it — no wind protection foam included. So if I accidentally spit on the mic while talking, don’t blame me — blame the manufacturer.
The charging case is relatively compact. Everything in the case is neatly arranged and held in place with magnets, including the lid. The case charges via USB-C and has a display showing battery percentage and icons for the mic battery levels.
You can charge the mics either through the case or directly via USB-C, which is essential for the version without the case. However, the USB connection is only for charging. If you plug the mics into a computer, they won’t be recognized as USB audio devices — you must use them with the dedicated receiver. They also don’t work over Bluetooth.
This set includes two receivers: one USB-C and one Lightning, meaning the mics are compatible with both “normal” devices (phones, tablets, laptops with USB-C) and the “crippled” ones with Lightning ports. Each receiver also features passthrough charging, so you can charge your phone while using the receiver. The USB-C receiver has a USB-C input, and the Lightning one has a Lightning input.
The receivers don’t have their own batteries — they draw power from the connected device.
Each mic has two buttons: power/mute/volume functions, and a clip for attaching to clothing or even a necklace (trendy, right?).
There’s also a USB-C port on the mic for plugging in analog headphones (via USB-C or 3.5mm jack with an adapter). This lets you monitor your voice in real time. Just note: USB-C headphones with built-in DACs (digital audio converters) likely won’t work — the mic is recognized only as an input device, not for playback.
So no, you can’t send background music to the person wearing the mic — the receiver isn’t a transmitter. No monitoring of mix or accompaniment. But there are some fairly useless features like noise suppression and reverb, which I personally ignore. Noise suppression in these kinds of devices is usually terrible.
Also, the receiver’s plug might be too short if your phone has a thick case — in that case, you’ll need a small USB-C extender. And if your device doesn’t have USB-C at all, you’ll need an adapter to USB-A.
As for the mics themselves, each has two capsules — why, I don’t know, since they record in mono. Both mics get mixed into a single mono track — no left/right separation. But the sound quality isn’t bad, especially compared to other cheap wireless mic kits I’ve tested before. At least it won’t make your ears bleed.
Also, this kit is insanely cheap. The single-mic version without a case is practically pocket change. But having two mics is useful for things like interviews.
For this video, as usual, I’m recording all the sound using this very mic — no post-processing at all. No volume boost, no compressor, no noise reduction. What you hear is exactly what the mic recorded.
Specs:
Max distance between mic and receiver: 20 meters
Latency: less than 20 ms
Charging time: case charges in 1 hour, mics in 30 minutes
Battery life: several hours, depending on distance and usage
If you’re curious, the system identifies the receiver under a generic weird name.
In conclusion — this kit is surprisingly decent. Probably because Retekess also makes mics for semi-professional and stage use. Yes, they’re very much Chinese-made, but they’re not bad at all. So if you’re in the market for something like this, you’ll find the purchase link, as always, in the description.
