## Product: 1Mii B03 Bluetooth Transmitter Receiver
**Brand:** ‎1Mii

If you're thinking about using the 1Mii B03 Bluetooth 5.3 Transmitter Receiver with two pairs of headphones, there's an important detail to keep in mind regarding latency. 

The good news is, it can stream audio to two Bluetooth devices simultaneously, whether they're headphones or speakers. But here's the catch: when you connect two devices, it can't use aptX Low Latency. This feature only works when you have just one device connected. So with two headphones, it switches to regular aptX, which might cause a bit of a delay—something fairly common with Bluetooth setups. 

According to our research, folks who've used the 1Mii B03 have noticed this lag too. It's worth thinking about if you need perfectly synced audio, like for gaming or watching videos. The delay might make those experiences less smooth than you'd hope. 

On a positive note, the 1Mii B03 does a nice job with audio quality and has a pretty good range, so it's a solid choice for everyday use. Just keep in mind that it's best with one audio connection if you're aiming for low latency. Also, make sure your devices support the aptX codec to get the best audio experience. 

Another thing to note: volume control usually depends on the headphones you're using, as the 1Mii B03 doesn't always adjust volume directly, according to some feedback we've come across. 

So, in short, the 1Mii B03 works great for single connections with low latency. But if you're planning on using it with two headphones at the same time, be ready for some possible delay due to the lack of aptX Low Latency support. It's something to consider based on your audio needs.
