Powerful Audio Performance with Deep Bass Enhancement
Despite its compact size, the BS157 delivers impressive audio quality that punches above its weight class. The 57mm full-range driver produces crisp, clear mids and sparkling highs, while the integrated passive radiator bass diaphragm adds surprising depth and warmth to low frequencies. This thoughtful acoustic design creates a well-balanced soundstage that brings your music to life, whether you’re listening to bass-heavy EDM, acoustic folk, or podcast dialogue. The 5W RMS power output ensures consistent, distortion-free volume levels suitable for small to medium-sized rooms, outdoor gatherings, or personal listening. The frequency response range of 85 Hz to 20 kHz captures the full spectrum of audible sound, ensuring you hear every detail from deep bass drops to delicate cymbal crashes with remarkable clarity and precision.
TWS Mode for True Wireless Stereo Experience
Elevate your listening experience by activating TWS (True Wireless Stereo) mode, which allows you to wirelessly pair two BS157 speakers together. This innovative feature creates authentic left-right stereo separation, dramatically widening the soundstage and immersing you in three-dimensional audio. Perfect for movie nights, gaming sessions, or parties, TWS mode transforms your audio setup from mono to stereo without any complicated wiring or configuration. Simply activate TWS on both units, and they automatically sync to deliver synchronized, high-quality stereo sound. This feature is particularly impressive for music with distinct instrumental separation, providing spatial awareness and depth that single-speaker setups simply cannot match. Whether placed across a room or flanking your TV, paired BS157 speakers create an enveloping sound environment that enhances every listening experience.

This all-day performance means you can soundtrack your entire day—from morning workouts to evening relaxation—without worrying about recharging. The compact dimensions (87.5 x 87.5 x 114.2 mm) and lightweight construction (just 370g) make this speaker incredibly portable. The durable shell is designed to withstand the rigors of daily transport, easily slipping into backpacks, handbags, or carry-ons without adding noticeable weight. Whether you’re heading to the beach, camping, studying at a café, or setting up at a friend’s place, the BS157 travels effortlessly while maintaining its premium build quality and reliable performance throughout countless adventures.
Atmosphere-Setting RGB Lighting
More than just a speaker, the BS157 NeraBox doubles as an ambient lighting device with integrated RGB illumination. The dynamic lighting system cycles through a spectrum of vibrant colors, creating visual ambiance that complements your audio experience. Whether you’re gaming with friends, hosting a party, or simply relaxing after a long day, the customizable RGB glow sets the perfect mood. The lighting can be easily controlled via dedicated buttons, allowing you to select your preferred color scheme or turn it off entirely for battery conservation. This dual functionality makes the BS157 particularly appealing for desktop setups, bedside tables, or as decorative accent lighting in any room. The RGB feature transforms the speaker from a simple audio device into a complete sensory experience that engages both sight and sound.
Hands-Free Calling and Intuitive Controls
The BS157 isn’t just for music—it’s a complete communication device. The built-in microphone enables crystal-clear hands-free calling, making it convenient for conference calls, video chats, or catching up with friends while multitasking. Voice prompts provide helpful feedback when switching modes or connecting devices, ensuring you always know the speaker’s status. The thoughtfully designed control panel features dedicated buttons for all essential functions: play/pause, track navigation, volume adjustment, mode switching, and RGB customization.
