Tronsmart Bang was upgraded in 2023, Some of the upgrades to the speaker are very noticeable, while others not so much. The first thing I noticed was the highlighting of the user buttons on the top of the speaker. They are now lined in white on top of the black rubber.
The one change that is not visually seen but is nice to have is the upgrade from Bluetooth 5.0 to 5.3.
Tronsmart mentions that the battery is upgraded to optimize the performance of the battery and playtime.
The last upgrade mentioned is “As driver units upgrade, the sound quality is optimized with richer bass much better than before.”
