The sound bar is great and the price was as well!
February 6, 2019
Love it!
I'd give it a 4.9 out of 5. This setup is sleek, feels quality, heavy base speaker for the size, elegant, sound bar feels well made, simple setup with just a little tech knowledge (like anything else these days). After downloading the app it indicated a new firmware was available.......I like that.....means there's a better chance of compatibility in the future with the ever changing digital age. It connected to my WiFi through the app quickly. My iPhone, iPad and TV found the setup without any issues, very easy, like any other Bluetooth device. I like that the front sound bar grill IS NOT made of felt or other fabric so it doesn't collect dust or is hard to clean, cats won't mess with it!

The only small grip I have is the indicator lights are minimalist and on top so looking from the front of the sound bar there's no indication that it's on or what it's connected to. I guess depending if you hate lights distracting you while watching TV this could be great but how my setup is positioned it's a guess at the status of the sound bar while it's just sitting there.

All in all, I LOVE IT!

I used the comparison data WWS provided to make a choice in selecting H/W. I compared prices elsewhere and could not do any better than WWS. I felt WWS should get my business since they provided detailed product information.

  Yes, MusicCast speakers can be set up as rear speakers for any MusicCast enabled soundbar or AVR. Thank you!
Can you adjust treble & bass?
Randy on Mar 20, 2019
  Thanks for the question. Short answer: the unit does not have a bass or treble control. However, the unit features a bass extension option selected on the remote and a clear voice option that improves dialog clarity, also selected on the remote. I personally like the pure voice option far better than any treble control.
Is hdmi arc, or will it turn on and off when tv is turned on?
A shopper on Aug 18, 2019
  HDMI-CEC allows a TV and audio system to share power and input commands, but not all products are compatible. HDMI-ARC is the audio link between the TV and the soundbar.
I have a set of Samsung swa-8500s wireless rear speakers would it connect to the musicCast bar 400 sound bar?
Franc D on Aug 8, 2019
  Only specific Yamaha MusicCast speakers can be used as wireless surround speakers with compatible MusicCast soundbars and receivers.
Can the soundbar be wall mounted?
ritchie m on Jan 4, 2019
  The BAR 400 has keyhole slots on the rear panel for wall mounting.
