Best Bluetooth Transmitter to Pair with Two Headphones
Compared with previous models from TROND or other brands, TROND BT-DUO II is far superior in enabling you to pair with two BT headphones (speakers). Reasons are:

- Two Separate Buttons. It’s much easier to operate and set up all the connections with the power button and the pairing button so that you won’t get confused with the so-called multi-function button;
- Two LED Indicators for TX. In the TX mode, it features one blue indicator to show which codec is in place, and another green indicator to show whether both BT devices are successfully connected;
- AptX Low Latency for Two Devices. What really makes TROND BT-DUO II stand out is that it can support aptX Low Latency for TWO paired Bluetooth speakers or headphones, whereas most other competing transmitters in the market can’t. Instead, they will downgrade the codec to SBC, which may lead to the noticeable audio latency.

IMPORTANT:
- The latency of 40ms is still unacceptable for live performance. Therefore, musicians beware! Bluetooth technology even with aptX LL may not suit your needs;
- If you use the optical connection, please change your TV SPDIF output setting from Dolby Digital to PCM.
- TROND BT-DUO II does NOT function as an audio converter; therefore, please do not expect to use the 3.5mm AUX and optical IN simultaneously.
