Short answer: the Vifa Oslo for treble detail, but the notes point to the Helsinki. The Oslo delivers extreme treble detail with decent bass, full and natural sound at higher volumes, rich bass from opposing 65mm woofers, Kvadrat wool fabric and a 10-hour battery, though it has a dip at 270Hz. The notes say the cheaper Helsinki has a more neutral response and recommend it instead, while the Dali is called horribly overpriced.
Buy the DALI Katch G2, since the Vifa Oslo is discontinued and only worth hunting down used.
If water resistance matters to you, the DALI Katch G2 at IPX7 (brief submersion) holds up far better than the Vifa Oslo at no water resistance.
