  • APTX & APTX LOW LATENCY SUPPORTED. Powered by premium CSR8670 chipset, TROND BT-DUO supports the latest Bluetooth V4.1, whereas most of others on Amazon are V4.0, V3.0 or even V2.1. With aptX, you can enjoy CD-quality sound wirelessly over Bluetooth connections with aptX-source devices like TV’s, phones or tablets. With aptX Low Latency, you can now watch video while listening to wireless audio in a synchronized fashion and without any noticeable audio delay
  • BLUETOOTH TRANSMITTER MODE (TX). TROND BT-DUO can transmit stereo audio wirelessly from your non-Bluetooth audio sources such as TV, MP3, CD player, PC, or Nintendo Switch/3DS to your Bluetooth-enabled headphones or speaker. This way, you can enjoy high quality music wirelessly, or listen to late night shows without disturbing your loved ones while they sleep. Please also order TROND TD-BH01 Over-Ear Bluetooth V 4.2 Headphones for the best low latency performance
  • BLUETOOTH RECEIVER MODE (RX). Previously TROND BT-DUO only supported aptX LL & aptX in the transmitter mode, and we have just added aptX LL & aptX into the receiver mode as well. Now you don’t have to pay high premium to get aptx LL-enabled wireless headphones or speakers; instead, your wired headphones or speakers can be easily turned into wireless audio devices with low latency
  • DUAL STREAM & MULTI-POINT. As a transmitter, TROND BT-DUO can be paired to two Bluetooth Headphones or speakers, and streams audio to both of them simultaneously. As a receiver, it can still be paired to two of your smartphones or tablets, but the receiver can only receive the audio from one of the two paired devices. Please note that TROND BT-DUO only supports the codec of SBC when paired with two devices simultaneously.
  • WHAT YOU GET: TROND BT-DUO 3.5mm Bluetooth V4.1 Transceiver with aptX Low Latency, USB to micro USB charging cable, 3.5mm male to 3.5mm male audio cable (50cm long), 3.5mm female to RCA male audio cable, user manual in English, 18-MONTH TROND warranty & 30-DAY money back guarantee

Product Description

Product Specifications:

  • Bluetooth Compliance: Bluetooth V4.1, CSR 8670 chipet, A2DP
  • Transmit Range: up to 33ft / 10m, if without blocking objects
  • Supports: Dual Stream (TX mode); Multi-Point (RX mode)
  • Codec: aptX Low Latency, aptX, SBC
  • Working Time: about 8 hours
  • Charging Time: 2 hours / 5V
  • Dimension: 1.81 x 1.30 x 0.38 in
  • Net Weight: 0.51 oz

Important Remarks:
  • TROND BT-DUO doesn't have the built-in microphone and hence doesn't support phone calls;
  • You can use TROND BT-DUO either as a transmitter OR as a receiver. This adapter won't be able to transmit and receive audio simultaneously;
  • The latency of 40ms is still unacceptable for live sound monitoring. Therefore, musicians beware! Bluetooth technology, even with aptX Low Latency, may not suit your needs;
  • If TROND BT-DUO gets stuck and all the buttons stop working properly, please press & hold the MFB, and then plug in the external USB charger to force down BT-DUO. Please note that this operation won't delete the previous pairing records;
  • If you'd like to delete all the pairing record, please try to reset TROND BT-DUO by switching between two working modes (TX/RX). For detailed steps, please refer to the section of "Frequent Asked Questions" at the end of the included user manual;
  • If your TV only offers the digital optical (TOSLINK) port, you will need a digital to analog audio converter to set up the connection. Or you could order a different Bluetooth transmitter, which supports both 3.5mm and digital optical interfaces;

 

Mode I: Bluetooth Transmitter (TX)

TX Application:
Switch its working mode to "TX", connect it to the audio OUT port of your non-Bluetooth audio source, such as TV, iPod, CD-player, e-Book reader or Nintendo Switch/3DS, and then pair it with your wireless headphones. This way, you could watch video, enjoy music or play games without disturbing someone next to you.

Lip-Sync with AptX Low Latency
With the latest aptX Low Latency (LL), it can effectively minimize the audio delay, which allows you to watch late night TV shows without experiencing lip-sync issues. Please use with TROND TD-BH01 Over-Ear Bluetooth V4.2 Headphones for the best low latency performance.

Dual Stream
TROND BT-DUO can be paired to two Bluetooth audio devices, dual stream audio to both of them simultaneously. However, in this case, the codec would be downgraded from aptX LL to SBC. Please order TROND BT-DUO II if you'd prefer aptX LL for two devices.
 

Mode II: Bluetooth Receiver (RX)

RX Application:
Switch its working mode to "RX", connect it to the audio IN port of your wired audio device, such as wired earbuds, speaker or car stereo via 3.5mm cable, and pair it with Bluetooth-enabled audio sources such as your smartphone, tablet or laptop. This way, you could enjoy high-quality music wirelessly without spending more to order Bluetooth headphones or speaker. 

AptX Low Latency for RX Mode
Most other 2-in-1 transceivers in the market don't actually support aptX LL or aptX in the receiver mode. As the pioneer in adding both aptX LL & aptX into the receiver mode, TROND BT-DUO offers an economical solution by turning your old wired headphones or speakers into Bluetooth headphones or speakers with the feature of aptX LL.

Multi-Point
You can pair two smartphones (or tablets) to this receiver simultaneously. However, it can only receive the audio from one phone at a time. You need to pause the music on one phone first in order to play music from the other phone.
