Q) Is this compatible with Fire TV/ Firestick?

A) Yes, plug the Fire TV to the TV. And connect the TV using any input mode. If using HDMI ARC, please 

make sure you have followed our manual setting.

Q) When you purchase two or more sets of this product and turn on two or more speakers at the 

same time, the microphone may not be able to connect to the speaker you 

specified?

A) This is because each set of speakers and microphones uses the same wireless connection technology, 

so connection crosstalk problems cannot be avoided. 

You can try below methods if you meet relative problems.

Method 1: Please use the sequential connection method. First turn on the first speaker and connect the 

two matching microphones. Then turn on the second speaker again and connect the second set of 

microphones.

Method 2: Only use one set of speakers and microphones at the same time, and turn off other speakers 

and microphones.

Q) What to do after the speaker crashes? 

A) When the speaker crashes, insert a cotton swab into the Line In interface on the back of the speaker. 

There is a button inside the interface. Press and hold the cotton swab for 2 seconds to force the speaker 

to shut down, and press the power button again to turn it on.

Q) How to handle howling sounds? 

A) When the speaker is too close to the microphone, it will produce a howling sound, which is normal  performance. To avoid this howling, please keep the distance between the microphone and the speaker at least 12 inches.
