Very Pleased
This speaker meets my expectations as an additional room speaker. It was easy to set up on the fridge against a kitchen wall opposite our YAMAHA RX-V4A Receiver, which is in our den. It powers up whenever the receiver is powered on in the MusicCast App, and the sound is rich. Very pleased.

Great Wireless Speaker for Yamaha MusicCast Systems
Integrates well with my Yamaha RX‑A2080 receiver. I didn’t want to run wired speakers to my walk‑in closet and restroom, and the MusicCast 20 wireless speaker solved that perfectly. The sound is great, and it connects easily to my iPhone. I only purchased one, but I can see how these would work well as rear or presence speakers. It definitely saved me money by avoiding ceiling speakers. The price is fair for the quality — you get what you pay for.

Works fine as surround
The build quality of this speaker is great, very nicely designed, the sound is just fine but isn't worth it if you don't want to use it as wireless surround speaker. Connection is relatively easy: 1. Get musiccast controller app 2. Add your receiver first 3. Then add wireless speakers( I had issue connecting to virtual network it creates during the setup but it solved by restarting my phone and the speaker once) And that's it, just don't forget to turn surround speakers on in your receiver settings. Just 2 points: 1. If you you want to use them as surround speakers they can not be used as separate stereo speakers. ( you need to release speakers from your receiver within the app and then set them up as a stereo pair) 2. These speakers cant be used as zone 2 (basically zone 2 speakers must be wired) I'm happy with my purchase as there’s no alternative for wireless surround speakers as far as I know and I hate wires.

Steps to add Speakers to 5.1.2 Surround Sound
Great speakers once you get them connected, the problem is that was a huge headache for me (at first). So much so, that I spent 3 days tinkering with these and my wireless network settings to no avail, only to box everything up in frustration with the intent on sending it all back. Fortunately, once I cooled off and waited for the holiday weekday to pass I called Yamaha, and thankfully they got me working. Initially, I could only get one speaker to add to my wireless network, but the second speaker simply would not add. I thought maybe it was a bad speaker, so I exchanged it at the store, but sure enough the new speaker also would not connect. After 3 days of trying, I finally called Yamaha, and they said it was common, and that a better method was available (though not in any manuals or guides). SO, if you are pulling your hair out trying to get your receiver and two speakers to connect for rear surround sound, here is the EASY way (using a receiver and two speakers): 1) HARD WIRE the receiver over ethernet and add it to the Yamaha Music Cast app. 2) Temporarily HARD WIRE the first speaker via ethernet as well, then add the device in the music cast app (give it a specific name like “Surround Left”) 3) Click on the SPEAKER in the music cast app, and go to information > network settings (then notate the IP address) 4) Open a browser on your PC, and go directly to the IP address of the speaker 5) Click on network settings 6) Click on "wired" and it should let you change it to "wireless" 7) Enter the SSID, security type, and password of your wireless network, then click OK 8) Disconnect the ethernet cable, & reboot the speaker (it should connect on its own over wireless now) 9) Now REMOVE the speaker from the music cast app altogether 10) Since the speaker is still connected to your wireless network, you should be able to reconnect it back into the music cast app by holding down “connect” on the top of the speaker for 5 seconds. 11) Repeat steps 2-10 with the second speaker 12) Once the receiver and two speakers are showing up in the app, CLOSE the music cast app completely (swipe up on an iOS device) 13) Re-open the app, click on the receiver, choose "music cast surround speakers" and now add the two speakers. 14) Once you see the “successful” message you should be set with wireless surround. Why these speakers have so much trouble being added wirelessly, or why Yamaha does not add the above steps in their manual is beyond me, but now that everything is connected properly they work great! ALSO: While the advertisement of the Yamaha Receiver and these speakers say they only work in 5.1 setups, the receiver DOES allow adding two extra "front presence" (i.e. height) speakers, making it 5.1.2 ....... (which is basically like 7.1), FYI ****** 8/6/19 UPDATE ***** I noticed after a while the speakers began going "in and out" occasionally. To fix this (which may have been overkill, but it worked for me) I moved everything wireless in my house to my 2.4Ghz "N" network, and reserved my 5Ghz "AC" network for nothing but these speakers. I also put a network extender in the room where these speakers are, so that the signal was uninterrupted through walls. Once I did those two things they've never once sounded choppy. Hope this helps others =)

Extremely unreliable!
Absolute rubbish. I purchased two of these. One simply will NOT connect. The other connects only intermittently and will NOT sync with video. They are landfill material. DO NOT PURCHASE!

Proprietary wireless REQUIRES CONSTANT WI-FI.
Almost not worth the setup hassle. This could be simplified without the app. When I bought the sound bar from a home theater store they were not in a hurry to recommend the speakers for the rear channels. I NOW UNDERSTAND WHY! They do not have the implied ease of connectivity via proprietary wireless or just blue tooth!!! They require WiFi or simply will not work. The sound bar works fine and sounds fine. The Bluetooth alone will drive you nuts because every time you connect the app WITHOUT using the WiFi support it will want to pull a Bluetooth signal from a more pure source, like your phone! Yamaha skip the app! Use a simple onboard pairing button and your own proprietary remote control supplied with the sound bar! Why create conflicting controllers that fight with each other???!!! As others have said, once you get past the hours of frustration the ‘room-filling surround sound ‘ does sound like what you want. The difficult process should be streamlined without the app. The app took its time delivering firmware to the speakers before they were functional. The setup literature makes no mention of requiring both Bluetooth connectivity and WIFi. This is why the Audio on this product is better, but the overall satisfaction mediocre. The design needs work.

I bought the soundbar yas 408, a month back and was very impressed with the sound quality. However I was missing the wow factor. Now added the two music cast speakers and I am pleasantly surprised with the amazing surround sound experience. The only downside is that these are very expensive. I suggest all owners of the music cast sound bars to invest in the surround speakers to enjoy the high quality immersive experience
