The Best one from Yamaha

Expensive but worth it
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

Poor documentation for setup, administration and resolving surround pairing
I am writing this review around a Yamaha musiccast WX051 pair + YAS408 - trying to setup the WX051 pair as surrounds for the YAS408. Even though this product is a WX021 the concepts I write about should help here. I benefitted by reading some of the customer experiences on this product. My first post here. I read this full thread because I started having trouble with adding a pair of WX051 as surrounds to a YAS408 Bar. They kept failing with errors 6000B0000, 600b30000, 600330000. Some history here. I had a single WX051 which used to pair as surround with the YAS408 easily. I never had any trouble unpairing and pairing it as surround. Then I got a second WX051 to make a real surround with the YAS408. I noticed the surround setup kept failing. Actually I had not use the first WX051 as a surround with the YAS408 for a few months. I tried the singleton WX051 as a surround with the YAS408. It failed. That was puzzling. I knew that worked well flawlessly. Then I came to this forum and read all the posts. Instead of static IPs I made sure my DHCP server will assign reserved IPs for my two WX051 and one YAS408. This is as good as static IPs. This also did not work. Then it struck me I had done one change in my home network. In my home I have two WiFi access points. Initially I used to have separate SSIDs on both Wifi access points. In fact I also had separate access points for 2.4G and 5G. Earlier I had configured my single WX051 and YAS508 on the SSID given to the 2.4G. I had trouble with my laptops and phones as I moved around the house and often they would not shift to the stronger SSID. After reading some stuff on Wifi, I decided to make both my access points use the same SSID (including 2.4G and 5G). This definitely helped my roaming inside the house. (NOTE both Wifi access points are just ethernet-wifi radios. The DHCP server was common from a router to which both access point connected). When I started testing with the second WX051 I did not realise my Wifi topology had changed. I realised that it is quite likely my YAS408 was probably connecting to access point 2 (it is in a location where both access points have nearly similar signal strength) but the WX051 was connecting to access point 1. (both using same SSID also same SSID for 2.4/5G and both access points in the same IP subnet). I read here and in one Amazon customer feedback that the Yamaha devices establish their own ad-hoc network. I argued that if the Yamaha devices are not connected to the same access point they refuse to form the adhoc network - because Yamaha in their design must have assumed that such Wifi arrangement will only happen when there are large distances - and in such cases there was no way surround can be created. So I switched off all Yamaha devices. Switched off my distant Wifi Access point and powered on my Yamaha devices (two WX051 and one YAS408). Went back to the musiccast app on the phone and trie setting up surround on both WX051. IT worked in first attempt without any issue. Once the surround was setup, I went back and turned on the second access point. No problem with surround working. Conclusion : I think for the Yamaha to form its adhoc network for surround, it expects all its devices are talking to the same Wifi Access point Radio.

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.

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.

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 =)

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!

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.
