For the sound, you do need to update the product in the app, which makes a difference. To achieve a wider stereo image, I bought two. Because I found the bass sounding a bit muddy, I turned it down a bit in the app. Afterward, the speakers sounded much tighter.

Beautiful design and was surprised by the sound. The second one is going on order. Two side by side (you can easily pair them) and connected to the TV via Bluetooth. (Put a 2.4g adapter in between and the sound is milliseconds slower than the TV). Add some popcorn and enjoy.

According to our Bluetooth speaker expert
The Constant Sound Field technology provides a wide sound range, so you can hear many details in the music.
Because the speaker adjusts the sound to every room, you can listen to full and detailed sound in every room.
With the 8-hour battery life, you can listen to music the entire afternoon without problems.
The speaker isn't dust-resistant and water-resistant, so you can't place it outside.
