ChunHee Window Speaker Intercom System Anti-Interference Dual-Way Intercommunication Microphone and Speaker Bank Window Intercom Glass Window Microphone for Business/Bank/Office/Hospital

This worked much better than I expected! I have an office window and wanted to keep it closed to limit customer interactions due to COVID. This is loud enough and the volume is adjustable. The mics on both sides pick up voices well. The sound is not perfectly clear - it sounds like a drive-through or bank teller window - but good enough to be understood. Would buy again!

I used this to service clients outside without having to fully open our sliding window during corona virus. Road noise made it really hard for clients to hear us before we got the intercom speaker. Easy to set up and will get us through the season of not being able to allow customers in the office due to corona virus restrictions on small office/business.

Best value for the money. I purchased 2 over a month ago to use in our school office. We're surrounded by plexiglass and wear masks, these make it easier to communicate.

This is a great little speaker system. We used it during COVID when we were social distancing. Would recommend.

I purchased this item to use for my aid at school. She sits inside a cubicle with windows while the students sit on the outside between partitions. I am thrilled with the clarity of her voice and am very happy with my purchase!

I own a hot dog stand and with this pandemic we have a sheild between customer and cashier. Very hard to hear customers when taking orders, but with tgis window speaker it works out great. Customers are not repeating themselves to us.

The sound of this speaker is no good And it echoes a lot

This does exactly what I needed it to do. I have no complaints so far.
