Short answer: the KEF Muo gen2 if sound quality matters most, the Klipsch Groove/Heritage Groove if price matters most. The KEF Muo gen2 ranks #73 of 136 medium speakers at $249.99. The Klipsch Groove/Heritage Groove ranks #90 at $89, $160.99 cheaper.
What the KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
What the Klipsch Groove/Heritage Groove offers: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life. Watch for: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
Buy the KEF Muo gen2 when sound quality outweighs the price for you, and the Klipsch Groove/Heritage Groove when the price outweighs sound quality instead.
There is a real battery-life gap here: the KEF Muo gen2 is rated for 24 hours, the Klipsch Groove/Heritage Groove only 8 hours.
If water resistance matters to you, the KEF Muo gen2 at IP67 (brief submersion) holds up far better than the Klipsch Groove/Heritage Groove at IPX4 (Groove), none (Heritage Groove) (splashing).
