Energy Sistem Energy Music Box B2 comes with a boxy design. The front side has speaker units with Energy Sistem branding. Back side has micro USB port and 3.5 mm audio port. These are covered by a rubber panel.

The top side has music control buttons including volume rockers, bluetooth search button, play and pause button along with previous and next track buttons. Here, one thing to note that the play and pause button acts as power button as well. When I first unboxed the speaker, I was clueless how to turn it on. Top and base side have rubber layer. So, it does not slide off shiny surfaces.

Dimensions measure 143 x 57 x 30 mm that makes it shorter than smartphones. It weighs 214 grams. So it is portable and you can even carry it in your pocket. It doesn’t take much space in bag.

It has two dynamic full range stereo speakers of 6W each. Here are the technical specifications.

SPEAKER

  • Speaker diameter: 40 mm
  • Signal-to-noise ratio: >80 dB
  • Frequency response: 80 Hz ~ 18 KHz

MICROPHONE

  • Sensitivity: -42 dB ± 3 dB

BATTERY

  • Capacity: 800 mAh

If I talk about performance, this device impresses. I tested with a range of songs and audio clips. It is loud and clear. Audio is good until you push it to highest volume level. If you keep sound level less than 85%, you will get excellent sound output. The sound is crisp and clear but the bass effect could be better. Well bass is restricted due to size. If you are bass lover, you will certainly be disappointed as Bass-heavy tracks will not be as good. Overall, it is good for home party. The sound is loud enough to give you and your friends a good music to dance.

It also has a built-in microphone, so you can attend calls as well. Voice input from this mic is fine and you will be audible on other side.

It has music controls to increase or decrease volume or go to preview or next song. All these controls work well. It supports Bluetooth 4.0 connectivity and also offers 3.5 mm auxiliary audio input. I tested the wireless range and it was fine for the distance of around 8 meter. After that, connection was not smooth as sound output was breaking.

It packs 800 mAh battery that perform really well. The battery life depends on the loudness of sound you play on this speaker. I was mostly on 80% of the sound level and got around 9 hours of battery backup. The battery takes around 2 hours in fully charging.

Final Words

Energy Sistem Music Box B2 is a good speaker at this price segment. It is priced at around Rs. 2000 and is good enough to compete with rivals. Its minimal design, still loud and clear sound impresses. If you are looking for a good Bluetooth speaker at this price segment, you can also consider this.
