Bluetooth speaker JBL GO 4 BLACK

JBL GO 4 Black – ultra-portable Bluetooth speaker with JBL Pro Sound

The compact JBL GO 4 Black Bluetooth speaker offers powerful JBL Pro Sound with deep bass, up to 7 hours of playtime, IP67 protection, and easy connection to your phone for music anywhere.

Description

JBL GO 4 BLACK is a mini Bluetooth speaker that combines surprisingly loud sound and deep bass in a body that fits in the palm of your hand. It is designed for people who want to take their music with them - in the city, on the road, at home or in nature, without compromising on quality.

Despite its compact size, the model relies on JBL Pro Sound with an output power of 4.2 W RMS and a frequency range of 90 Hz - 20 kHz, which provides clear mids and a deeper bass than expected for such a small speaker. The speaker is suitable for both background listening and more intense sound in small rooms, a work desk, a hotel room or camping.

One of its key strengths is the IP67 protection standard – the housing is waterproof and dustproof, allowing for safe use on the beach, by the pool, in the mountains or in the bathroom. The battery provides up to 7 hours of playback on a single charge, and with the Playtime Boost function, the time can be extended by up to 2 hours by optimizing the sound for more efficient operation.

The JBL GO 4 uses Bluetooth 5.3 for a stable wireless connection and more efficient signal transmission to smartphones, tablets and laptops. Supported A2DP 1.4 and AVRCP 1.6 profiles ensure reliable music streaming and convenient playback control.

The model also supports connection with other compatible speakers via Auracast, allowing for a larger soundstage when more power and coverage is needed. This makes it suitable for both individual listening and sharing music in a company.

The housing has a clean rectangular design with soft edges, a textured surface and a large embossed JBL logo on the front, and an integrated strap makes it easy to attach to a backpack, belt or hook. Some of the materials are recycled, which adds a sustainable eco-friendly accent to the product.

Control is intuitive with physical buttons on top for power, Bluetooth pairing, volume, and play/pause. Charging is via a USB-C port, making it compatible with modern chargers and cables.

Unique advantages and what it is ideal for

• Ultra-compact dimensions and weight of only about 190 g, allowing it to be carried in a pocket, small bag or attached to a backpack.
• Quality JBL Pro Sound with deeper bass than typical mini Bluetooth speakers in the same class.
• IP67 water and dust resistance, making it an excellent choice for the beach, pool, mountain, camping or bathroom.
• Up to 7 hours of playtime plus up to 2 extra hours with Playtime Boost – enough for a full day outing or a long night out.
• Multi-speaker connectivity via Auracast for louder, more immersive sound when other compatible devices are available.

The speaker is ideal for users who want maximum mobility - students, travelers, people who often work from different locations or want to have music everywhere. It is also suitable as a second, "pocket" speaker for a larger home system.
