Score: 79/100Rankings

The Soundcore Select 4 Go is an ultra-portable Bluetooth shower speaker offering up to 20 hours of playtime and IP67 waterproof, floatable protection.

Ideal for solo swimmers, shower users, and travelers who value portability and durability.

The Ultimate Ears WONDERBOOM PLAY is an ultra-portable cylindrical Bluetooth speaker offering 10 hours of playtime, IP67 durability and a 40 m range.

Professional reviewers consider the Soundcore Select 4 Go a best-budget portable speaker, praising its punchy, clear sound, strong bass for a 5 W driver, and the flexibility of a 9-band EQ app. The IP67 rating and floatable design earn high marks, as does the seamless Bluetooth 5.3 and TWS pairing. The main criticism from editors is the limited maximum volume, which makes it unsuitable for larger gatherings, and the omission of a wall charger.
Everyday users love the long 20-hour battery, the surprising bass and clarity for such a small device, and the rugged waterproof, floatable build that survives showers and pools. Common praise centers on portability, easy TWS pairing, and the customizable EQ. Recurring complaints focus on low maximum volume, occasional Bluetooth connectivity hiccups, and the missing wall charger.

Professional reviewers commend the WONDERBOOM PLAY for its feather-light build, IP67 durability and impressive 40 m Bluetooth range, noting that it delivers a surprisingly big, 360° soundstage for its size. However, they criticize its mediocre sound accuracy, limited low-frequency extension and a lower maximum SPL of 79 dBC, which makes it less loud and less precise than earlier Wonderboom versions.
Everyday users love the speaker's portability, floating capability and long battery life, frequently mentioning how easy it is to take to the beach, pool or on hikes. Common praise centers on the loud bass relative to its size and the hassle-free pairing. Recurring complaints focus on the lower overall volume compared with previous models and the need to buy a second unit for true stereo sound.
