How can the two microphones be used at the same time?

as another reviewer has mentioned, each microphone has to be set up on a different channel (see the instructions). Basically plug the receiver into the amp or mixer channel you wish to use then set the first microphone to a channel ( see instructions) the last microphone is then set to a different channel and linked the same way. Now you're set! Be aware that they will not have individually controlled volume since they'll be sharing the same amp/mixer input. IF you want individual volume control, you'll need to plug each receiver to a different amp/mixer channel! The mics are really good and a single channel should work fine! I hope this helps!

Can I buy extra receiver only

Yes. https://www.amazon.com/dp/B0B9SMYS4J

I feel that there is delay when i connect this device to an amazon echo speaker. should i change the speaker?

I have the same problem with delay - need answer soon !!

Does it support laptops? Or a bar speaker?

This should be fine, as the machine has three output modes, RCA 3.5mm and 6.35mm, and you can choose different connection modes according to your device

These microphones worked great. After a couple of months, one of them just suddenly stopped working. The seller was extremely accommodating and tried to help me troubleshoot. After that didn't work he sent me a full replacement set! Great customer service!
