Anker Soundcore Select 4 Go vs IKEA KALLSUP

The Anker Soundcore Select 4 Go is a better small Bluetooth speaker than the IKEA KALLSUP, particularly if you want to take it outdoors. It has water and dust resistance, a built-in carrying loop, and around 10 hours of battery life, compared with just under six for the IKEA. Neither speaker produces much deep bass, but the Anker's more balanced mid-range helps voices sound more natural. It also has dedicated volume controls on its body and a companion app with a graphic EQ, so you can adjust its sound to your liking. You can pair two Anker speakers for stereo playback. While the IKEA lets you link multiple units, it doesn't offer stereo playback but rather synchronized mono audio.
