Reviews last updated: August 2026 · How we calculate this

What customers like about Grundig GBT Club

  • Impressive and full sound quality even when used outdoors
  • Excellent battery life with up to 20 hours of continuous playback
  • Highly reliable Bluetooth connection with extended range and no noticeable audio lag when paired with TVs
  • Strong and deep bass performance enhanced by dual passive radiators
  • Robust and waterproof build quality (IPX7 rated) making it ideal for outdoor activities
  • Easy and seamless True Wireless Stereo (TWS) pairing to sync multiple units together

What customers don't like about Grundig GBT Club

  • Lacks native smartphone app support to act as a remote control or customize equalizer settings
  • Charging time is relatively slow, taking around 5 to 6 hours for a full charge
  • Uses an older Bluetooth version (5.0) compared to newer competitors on the market
  • No NFC support for quick, touch-to-pair connectivity
  • Lacks integrated voice control or built-in smart assistant compatibility

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.
