Manual of product Jam+
Editorial note
The Grundig Jam+ is a portable speaker that stands out for its optimal sound quality, thanks to its two speakers and an RMS power of 3.5 W. The TWS (True Wireless Stereo) technology allows for the wireless connection of two speakers, providing an immersive audio experience that will delight music lovers. Its modern design in black, enhanced by multi-color lighting, creates a personalized atmosphere, which is an additional asset for users. The impressive battery life of 30 hours, made possible by its built-in 2500 mAh battery, makes the Grundig Jam+ an ideal companion for long listening sessions without interruption. However, the 4-hour charging time may seem long for some, especially with intensive use. Despite its many advantages, the speaker has a few drawbacks. Its output power of 3.5 W may be insufficient in noisy environments or outdoors, thus limiting the audio experience. Additionally, the lack of FM radio function and memory card reader may disappoint users looking for greater versatility. Finally, although the weight of 240 g is reasonable, some may find it a bit heavy for a portable speaker. Overall, the Grundig Jam+ offers good value for money, considering its features. Its Bluetooth 5.3 connectivity and lightweight design make it easy to use and transport, although there may be reservations about its weight for some.Score details
