The JBL 104-BT is a pair of compact, powered desktop reference monitors designed to deliver accurate and detailed audio reproduction for content creators, podcasters, and multimedia enthusiasts in near-field listening environments. These speakers integrate professional monitoring principles into a user-friendly, space-conscious design, making high-quality audio accessible for home studios, editing suites, and personal computing setups. Each speaker is actively powered, featuring a built-in amplifier optimally tuned to its specific driver components. The system employs a 4-inch woven fiber composite woofer for controlled low-mid frequency response and a 0.75-inch silk dome tweeter for smooth, detailed high frequencies. This driver combination, combined with JBL's expertise in transducer design, provides a balanced and uncolored sound signature critical for making informed mixing, editing, and listening decisions.

A key feature that enhances the 104-BT's versatility is its integrated Bluetooth connectivity, allowing users to wirelessly stream audio from smartphones, tablets, or computers while maintaining a reliable wired connection for primary studio work. This dual-connectivity approach seamlessly bridges professional and casual listening tasks. The monitors also incorporate thoughtful user controls directly on the front baffle, including volume adjustment, input selection (between Bluetooth and the analog aux input), and a dedicated tone control switch to optionally enhance low and high frequencies for more enjoyable casual listening—a feature that can be disengaged for a flat, reference response when critical work is required.

The design prioritizes both acoustic performance and practical desktop integration. The enclosures are acoustically engineered to minimize resonance, and the front-firing bass port allows for flexible placement near walls without excessive low-frequency buildup. The sleek, minimalist profile with a distinctive wave-guide around the tweeter aids in creating a wide, consistent sweet spot. By combining respectable audio accuracy for their size with the convenience of wireless streaming and straightforward operation, the JBL 104-BT monitors serve as an excellent all-in-one audio solution for users seeking a significant upgrade from basic computer speakers without the complexity and space requirements of larger studio monitoring systems.
