The Fantech NeraBox BS155 is a compact, portable Bluetooth speaker designed for simple, reliable audio on the go. With Bluetooth 5.4 connectivity and a stated 10-meter wireless range, it helps you enjoy music, podcasts, and casual entertainment without constantly re-pairing or staying right next to your phone. Its 5W RMS output (1 × 5W driver) and 1 × 52 mm driver unit are tuned for clear, balanced sound in a small form factor—ideal for study sessions, short outdoor hangouts, or everyday listening at home.
Built around a 52mm driver and a 1.0 mono speaker layout, the BS155 focuses on delivering straightforward audio performance across a 100Hz–20kHz frequency response. This range supports both low-end presence and audible detail in the mid and high frequencies, making it suitable for a wide variety of content—from voice-heavy podcasts to mainstream tracks. If you want a portable speaker that’s easy to carry and quick to use, the BS155’s compact design helps you keep audio available wherever you set up your day.
Powering the speaker is a 1200mAh Li-ion battery, rated for up to 8 hours of playback at 50% volume. That makes it a practical choice for long study blocks, travel days, or casual listening without frequent charging. Charging is supported via USB-C, and the power rating is listed as 5V ⎓ 500mA, which aligns well with common USB power adapters and cables—helping you recharge conveniently at home or while traveling. For best results, consider charging before extended use and keeping volume around moderate levels to help maximize battery runtime.
Weighing 178.6 ± 5 g and measuring 65 × 79 × 79 mm, the BS155 is built for portability. Its small footprint makes it easy to pack in a bag or keep nearby on a desk, so you can switch from phone audio to speaker audio quickly. Compared to larger speakers that take up more space, this model is especially convenient for students and travelers who prioritize mobility while still wanting dependable sound for daily use.
With Bluetooth 5.4, 5W RMS output, USB-C charging, and a 1-year warranty, the Fantech NeraBox BS155 is positioned as a budget-friendly portable Bluetooth speaker for Bangladesh users who want a straightforward setup and consistent performance.
