User questions & answers

Question:	If I pair this device with a headset, will it automatically pair after that or would I need to pair every time I use the headset
Answer:	Mine does not auto pair to my iPhone 7. I have to go into Bluetooth settings and connect it manually each time.
Question:	Can you leave trond in transmitter mode plug into tv usb while in standby mode (on all the time
Answer:	I did this for a few months. The other person is correct that it will eventually shut its self off under continuous play while plugged into usb power because it doesn't charge while playing. After a few months, my unit will no longer charge and maintains a constant red light indicating it needs charging. I assume that keeping it plugged in all the time caused the battery to die an early death. There is no obvious way to open the unit, so doubting I can replace the battery. I wouldn't leave it plugged in now that I know this.
Question:	Does product have the latest APT-X Low Latency technology? Is there any audio lag using the device paired with bluetooth headphones for watching TV
Answer:	Update on Oct. 22nd, 2017 According to the chipset maker- CSR, your Bluetooth headphones or speakers also need to support the codec of aptX Low Latency in order to reduce the audio latency to 30~40ms. Otherwise, the codec will be downgraded to aptX or even SBC. Considering the fact that there're only several headphones on Amazon.com which could truly support aptX Low Latency, we've just released TROND TD-BH01 Bluetooth V4.2 Over-Ear Headphones. These headphones not only support aptX Low Latency, but also feature the smart codec indicators, which allow you to identify which codec is in place once the audio starts playing. Please check the link below for more product details. https://www.amazon.com/TROND-Wireless-Bluetooth-Headphones-Indicators/dp/B075VLWPXF/ref=sr_1_54?ie=UTF8&qid=1508681644&sr=8-54&keywords=bluetooth+headphones+low+latency+aptx Regards, TROND Customer Care
Question:	Can I purchase 2 of these and connect one to my home stereo and set as transmitter and one to my powered speaker as a receiver
Answer:	Absolutely. I just did it this week and works perfectly. I used one as the transmitter plugged into AUX out on projector and the other as the receiver plugged into AUX in on powered speakers and it truly elimnated the audio/video lag.

User questions & answers

Question:	Can I connect 2 units between them
Answer:	Yes as one of its varied purposes, this cable could be utilized to connect your Mixer's Outputs XLR to a Portable Digital Recorder or any 3.55mm Input.
Question:	Does this work on airplanes
Answer:	I am not sure what the "McLean v67g" is, but this cable has a left and a right XLR connectors that feed in fine into my soundblaster and my SigmaTel sound cards. I use this with a pair of Behringer XLR microphones just great. I have not used this device with any microphones that need phantom power, so if your Mclean one needs phantom power, I am not sure if this will work.
Question:	Can this be paired the Apple AirPods
Answer:	This cable is built for two mics for recording into a PC. One connector is left and the other connector is right. If you do not care about the sound being in stereo, then you can use one cable. Maybe you can even delete the unconnected channel and convert the one "mono" channel into stereo. I have purchased another cable that was specifically with one XLR plug to a stereo 1/8" plug.
Question:	When connecting device to a tv via the cables can you then transmit the audio to an iphone and play it on the iphone speaker
Answer:	About 14 hrs depending on volume if you are using the cord to play music from your device. However if you are in Bluetooth mode maybe 5 hours
