Verdict

The Grundig GBT Solo is an ultra-compact portable mono speaker featuring a 3.5 W RMS total output power paired with an integrated passive radiator for enhanced bass reproduction. Operating on Bluetooth 5.0 with True Wireless Stereo (TWS) technology, it provides an expansive wireless streaming range of up to 30 meters and boasts an impressive battery life of over 20 hours at 50% volume from its 1,050 mAh lithium-polymer battery. Weighing just 200 grams and measuring 90mm x 36mm x 72mm, the unit features an IPX5 splash-proof housing, an integrated microphone for hands-free calling, and a 3.5mm AUX input. Main pros include its exceptionally long playback time, extensive Bluetooth range, durable weather-resistant design, and budget-friendly compact mobility. However, its downsides consist of a relatively modest 3.5 W audio output that may lack power in noisy environments, limited single-channel mono sound staging unless paired with a second TWS unit, and an outdated Micro-USB charging port.
