We have tried the Halo while connected to our Android smartphone, the iPad Air 2 tablet but also on PC via stereo cable; the sound quality is great in terms of highs and mids and we were quite surprised how loud this speaker can get without distortions. Creative has build this product with two separate full-range drivers and advertises ?big bass? output; this is quite not the case when compared with Roar units which feature a dedicated subwoofer and also the stereo separation is a bit difficult to distinguish because the two mentioned drivers are quite close together.
