Sony Philippines released a new portable speaker in the country called the Sony Extra Bass SRS-XB31.

It has dual 48mm speakers, better RGB lighting effects, new sound modes, IP67 rated rugged body and the signature ‘Party Chain’ feature of Sony’s portable speakers.


Extra Bass and Live Sound Modes

The Sony Extra Bass SRS-XB31 has three sound modes – standard, extra bass and live sound.

As its name suggests, Extra Bass boosts the speaker’s bass and emphasizes low audio frequencies. It can be enabled by an long press of the speaker’s power button or through the Sony Music Center app.

Meanwhile, the live sound mode is new. Sony claims that it produces a “three-dimensional sound experience”.

The Sony Extra Bass SRS-XB31 has both Bluetooth and NFC connectivity. It can be controlled via a smartphone with the Sony Music Center app installed. Physical control buttons are also available on the speaker itself.

Its ports include a stereo 3.5mm audio jack for wired audio input, microUSB port for power input or charging and a full size USB port for powerbank function.


RGB Lighting and Party Chain

The Sony Extra Bass SRS-XB31 has RGB lighting that runs across its entire length, loops around the sides and runs back accross the bottom. Both ends of the speaker also have a flashing strobe light.

Of course, these lights sync to the beat of the music being played by the portable speaker.

Meanwhile, Party Chain allows users to connect and sync up to 100 units of Sony’s portable speakers. This makes the music louder and the RGB lighting also syncs across the different speakers.
