Soundcore is buying the parts the teardowns show them, so underlying innovation is happening anyway. So it’s just packaging of what to assemble, what parts, the cost Vs benefits impact.
Having frequent product releases does not accelerate innovation, it just causes more products, with downside of less support per product.
I’d advise Soundcore to wait til the underlying technology has improved sufficient to justify a new product, some years that may be once in a year, possibly two in other years.
Also the nearly identical products just cause downsides of consumer confusion and N+1 of otherwise fine units becoming idle.
The chipsets are public knowledge, a year ago there was Bluetooth 5.2 and more advanced multimode, I’d suggest wait til you can make a reliable product based on them.
I also think our views won’t cause any changes as we don’t understand their business as well as they do. For example, I don’t really know why the online Vs offline identical versions.
