Introduction

The Ultima Soundbox S50 is a locally-manufactured Bluetooth speaker from Nepali brand Ultima, designed to bring powerful audio to parties, outdoor gatherings, and everyday listening. With its claimed 50W stereo output, dynamic RGB LED lights, and IPX5 water resistance, this portable speaker aims to compete with established international brands at a fraction of the cost. Targeted at music enthusiasts, party-goers, and anyone seeking loud, bass-heavy sound on a budget, the Soundbox S50 promises premium features without the premium price tag.

Design & Build Quality

The Ultima Soundbox S50 features an ergonomic cylindrical design wrapped in soft fabric over a high-quality ABS plastic frame. The speaker measures 354mm (L) × 144mm (W) × 187mm (H) and weighs 2.07kg, making it portable yet substantial enough to deliver powerful sound.

A built-in carry handle adds convenience for transportation between locations. The speaker comes exclusively in black color with a modern aesthetic complemented by dynamic RGB LED lights that pulse to the music. With an IPX5 dust and water resistance rating, the Soundbox S50 can withstand splashes and light rain, making it suitable for outdoor adventures and poolside parties.

The overall build quality appears solid based on the official product descriptions, with the fabric wrap providing both visual appeal and protection for the speaker drivers.

Performance / Usage Experience

Based on the specifications provided on official product pages, the Ultima Soundbox S50 is designed to deliver room-filling sound with emphasized bass response thanks to its dual 90mm drivers and passive bass radiators. The 50W RMS output suggests sufficient volume for small to medium-sized gatherings.

The Bluetooth 5.1 connectivity should provide stable wireless connection up to 10 meters, while multiple input options (USB, AUX, FM Radio) offer versatility for users who prefer wired connections or radio listening.
