The 1Mii B03 Bluetooth 5.3 Transmitter Receiver can reach up to about 230 feet (70 meters) of range in open spaces, as the manufacturer claims. So if you're thinking about streaming music across multiple rooms or into your backyard, it should work well for that.
Now, if you're planning to use it with multiple devices, there are a few things to keep in mind. When you connect one device, it uses the aptX Low Latency codec, which is great because it keeps the audio in sync with the video—really helpful for movies or games.
But when you hook up two headphones or speakers at the same time, it switches to the standard aptX codec, which might make things lag a bit more.
And here's a bit of a heads-up: for the low latency magic to happen, all your connected gadgets need to support aptX Low Latency. If they don't, you might run into some lag or audio drops. This is a general Bluetooth issue, not something specific to the 1Mii B03.
Also, just so you know, the 1Mii B03 doesn't let you adjust the volume directly if you're using it as a transmitter. You'll have to tweak the volume from your audio source or your headphones, which can be a bit of a hassle if they don't have their own volume controls.
Overall, the 1Mii B03 gets a lot of love for its clear sound and wide range. If you're planning to use it for dual-device connections and need to keep audio synced, especially for TV or gaming, you might want to explore other options that handle multiple aptX Low Latency connections better.
