In the speaker test, the best Bluetooth and WiFi devices score highly with their rich sound and ease of use. However, only a few offer this complete package. Natural sounding bass, clearly audible details and balanced, lively sound - this is what the perfect speaker should sound like...

Soundcore's Boom 2 audio buoy has the edge. The battery life of 18.5 hours is great, making the Boom 2 ideal as a power bank. However, it did not want to charge iPhones when tested. Without the switchable bass boost, the sound is rather tepid; with it, the balanced and dry sound is fine...

The soundcore Boom 2 doesn't really slip up when tested. Compared to its predecessors, the Bluetooth speaker has not only improved in terms of design, but also in terms of technology and sound. The new robust and waterproof design may not look quite as elegant as a metal finish, but it doesn't give scratches and fingerprints a chance...

The Soundcore Boom 2 is a competent Bluetooth speaker at a more than fair price. It does make a few compromises compared to more expensive models: its sound is a little artificial, it doesn't get too loud and the choice of materials is quite cheap. However, the sound performance is perfectly adequate for relaxed listening to music, even in the morning shower.
