The Japanese word tsuyoi means strong and tough. And its certainly the right adjective to describe this speaker. The JUMPU Tsuyoi-S is a portable wireless speaker that features an IP65 rating, a speakerphone function, and an 8-hour battery life. It connects via Bluetooth v4.1 with a working distance of up to 10m. It also has a 3.5 mm AUX port for wired listening, as well as a X-Bass for enhanced bass.

Design and Build

You know just by looking at it that the JUMPU Tsuyoi-S is a rugged speaker. It has a distinct square shape and a thick, chunky body. The sides and edges are protected by rubber, while the body is made of hard plastic held in place by metal screws. It feels solid and well built. Although there are metal speaker grills on both sides, it only has one speaker.

Performance and Audio Quality

According to its documentation, the speaker has a working distance of around 10 meters. In testing, that wasn’t the case. The speaker started skipping audio within a few meters less than what was prescribed.

Pairing the device is simple enough. To connect, just turn on the speaker. A voice prompt will inform you that its now on. As soon as its on, the LED will blink blue continuously, which means its ready for pairing. Then go to the Bluetooth settings on your phone and connect to Tsuyoi-S.

Audio quality is above average. It decent sound, but lacks bass despite the x-bass feature. It has ample volume as well, even when outdoors. On full volume, some songs started to distort but not too much.

The Tsuyoi-S has a 1,500 mAh battery rated to provide 8-hours of playtime. It is decent for the size. During testing, I was able to get a number close to that. I brought it to the office and it managed to last a work day.
