Stable Bluetooth 5.4 connection for fast and secure connection One of the main advantages of the Fantech BS155 NeraBox speaker is the latest Bluetooth 5.4 technology, which ensures a stable and fast connection with less delay and greater energy efficiency. This standard enables reliable connection without interruption, even in rooms with several active devices. With a range of up to 10 meters, the BS155 provides complete freedom of movement while the music continues to play smoothly, without interruption or loss of signal. Thanks to fast synchronization, pairing with a phone, tablet or laptop takes only a few seconds, making the speaker extremely practical for everyday use. TWS mode for stereo sound that exceeds the dimensions of the device The Fantech BS155 NeraBox supports the TWS (True Wireless Stereo) function, which means that two identical speakers can be wirelessly connected into one stereo unit. When paired with a second BS155, the devices become left and right channels, creating an immersive stereo feel and spatial depth not otherwise obtainable from a single compact speaker. This mode is ideal for mini parties, watching movies, gaming, but also for creating a pleasant musical atmosphere in a larger space. Deep and powerful bass thanks to Deep Bass Boost technology Although small, the Fantech BS155 surprises with its sound power and depth. The built-in 52 mm driver combined with the closed acoustic chamber provides enhanced bass, clear tones and rich sound that fills the space. Deep Bass Boost technology contributes especially to low frequencies, providing an effect rarely found in such small portable speakers. Whether you're into electronic music, hip-hop, pop, acoustic instrumentals or podcasts, the BS155 delivers sound that makes an impact. Practical control via physical keys The speaker has simple physical buttons that allow full control of playback. You can change songs, increase and decrease the volume, select the operating mode and turn on the TWS function without having to reach for the phone. This kind of control system is especially practical during activities where quick reaction is important, such as training, cooking or work. Built-in microphone for hands-free calls JoшBS155 is not just a speaker for music – thanks to the built-in microphone, the device can also serve as an excellent tool for making hands-free calls. This makes it a great accessory for working from home, the office, traveling or situations where you want to have a conversation without holding the phone. Up to 8 hours of work on a single charge The built-in lithium battery with a capacity of 1200 mAh allows up to 8 hours of continuous music listening at 50% volume. This is more than enough for all-day activities, short trips, trips or office use. The USB-C connector ensures fast and efficient charging, making the speaker ready for use in no time.
