Cutting the Cord: Testing the UGREEN Bluetooth Transmitter

Venice setup + UGREEN adapter.

The UGREEN Bluetooth Transmitter has been a recent addition to my kit, a small but surprisingly useful piece of gear. The main appeal is the obvious… the lack of cables. When you’re moving fast, handheld, or working in unpredictable environments, the last thing you want is wires snagging on rigging or getting in the way of a quick reposition. The UGREEN device plugs into the headphone jack, pairs quickly with Bluetooth headphones, and surprisingly just works. Range is solid, probably beyond the quoted ten metres, and if it does drop out, it reconnects automatically. Charging is easy with USB-C, and I can power it straight from my Bebob batteries or via a D-Tap to USB-C adapter. The battery life is impressive—over a day, they claim, and I’ve never seen it die on a shoot.

But it’s not perfect. Latency is noticeable. I tested it with my AT-150 BT headphones, and even in low-latency mode, there’s a delay. This isn’t an issue if you’re just checking for mic rustle, wind noise, or general room tone, but it’s not something you’d want to use for serious audio monitoring. This is why I don’t record directly into the camera when I can avoid it. My preference is always to run a proper mixer—my full setup with the Sony Venice and Sound Devices 302 is detailed here: Old-School Audio with Modern Tech. But if there’s no sound recordist and no option for a mixer, the UGREEN is a quick and dirty way to check if the captured audio is at least serviceable.

This has been part of my evolving setup. For an upcoming job, I’m shooting on a Cooke 32mm S4/i Mini, which is a great match for the Venice’s size. I’m still using a DJI transmitter that slots neatly onto the battery port, though I’m waiting to test a suitable dual micro V-mount plate. The rig has shifted a bit; I’ve now positioned a monitor to the left where the EVF would normally sit, since this job is a lot of handheld from the hip and I don’t need an EVF at all. I’m using bolt-on rods by Wooden Camera with a 15mm receiver on the EVF rails. Still not an ideal solution, and I’m open to better ideas—so long as they don’t involve a Noga-style arm!
