Short answer: the Tribit Stormbox Micro 3. It ranks #6 of 62 small portable speakers against the Willen II’s #11, and it costs $73.23 less, which makes this an easy call rather than a real tradeoff.
Bass extension favors the Tribit. It measures 62Hz at -10dB against the Willen II’s 70Hz, and its 48mm NdFeB driver with coaxial passive radiators is built specifically around that low end. The Willen II’s pros describe it as more balanced than the original Willen with no sharp treble, but its cons still flag bass that isn’t very deep and a midrange that can sound congested at volume.
The Tribit adds hardware the Willen II simply doesn’t have: TWS pairing with a second unit, USB-C power bank output, a 9-band app EQ against the Willen II’s unspecified EQ, IP68 protection versus IP67, and a newer Bluetooth 6.0 radio with AAC support where the Willen II is limited to SBC. Its battery is also rated for 24 hours against the Willen II’s 17.
Buy the Tribit Stormbox Micro 3. It ranks higher for sound quality than the Marshall Willen II, costs less, and adds TWS pairing, a power bank, and a longer battery on top, so the Willen II has little left to offer at its price.
