Anker Soundcore Select 2S vs Soundcore Select 4 Go

The Anker Soundcore Select 4 Go is a better speaker for most use cases than the Anker Soundcore Select 2S. The Select 4 Go has a more balanced mid-range and a flatter treble, so cymbals aren't dulled slightly like they are when listening via the Select 2S. The Select 4 Go is also rated against dust ingress and is more portable than the Select 2S, so it's a better choice for taking on a hike with you. On the other hand, the Select 2S has a longer battery life and can reproduce stereo audio, although since the two drivers are positioned so close together, you don't get much of a sense of width.
