Verdict

The Grundig GBT Club is a compact 0.7 kg portable outdoor Bluetooth 5.0 speaker featuring a 2.0-channel stereo configuration with two drivers and dual passive radiators that deliver a total power output of 20 W RMS across a frequency range of 80 Hz to 20 kHz. Its primary advantages include a robust, waterproof IPX7-rated chassis, an extended wireless connectivity range of up to 20 meters, True Wireless Stereo pairing for connecting two units, a built-in microphone for hands-free calls, an auxiliary input, and a 4000 mAh rechargeable lithium-ion battery that provides over 20 hours of playback while doubling as a 5V/1A USB power bank. However, it lacks a dedicated travel bag, suffers from a relatively long battery recharging time of 5 to 6 hours, and possesses a slightly higher body volume than some modern competitors.
