Sony SRS XB 31 is another model from the most popular Extra Bass series. XB 31 is proudly made for the party. The speaker comes with a lot of features that you can’t resist buying.
Inside The Box
When you unbox the speaker, you will get a speaker, USB Cable, operating instruction, instruction Manual, and warranty card. All stuff placed very neatly.
Talking about its build quality, it’s exceptionally durable. The size of the speaker is ideal, not bigger or smaller, just perfect. Rated with IP67, the speaker is waterproof, dustproof, rustproof, which is something cool.
Speaker has some weight as it weighs 898 grams. XB 31 has a flashing strobe that adds more attraction. Sony has three kinds of sound profiles, i.e., extra bass, standard, and live sound.
Unfortunately, there are no dedicated buttons to activate these audio profiles. The buttons are present at the top of the speaker. These buttons are of power on/off, volume up, volume down, pairing, play/pause. All buttons are tactile and clicky. A USB, mini USB, and audio jack are covered under a rubber flap.
The speaker has a small rubber fits on which the speaker rests. But I think these feet are so little that they are not capable of handling the weight of the speaker. When the speaker gets loud, it starts to roll out, especially in extra bass mode.
Sony SRS Xb 31 has massive bass, and you can twitch the equalizer for a well-balanced sound.
Sony has a particular app to control the sound of the speaker with several customization options. For the excellent bass, you can set it on Extra Bass mode.
Extra bass mode fills your room with those high notes, and you are not able to listen to the lyrics properly. If you want a balanced sound with decent bass, turn the extra bass mode off and switch to standard mode. Again it’s up to you. If the beat matters for you rather than notes, go with extra bass mode.
The speaker has a unique feature. You can make different sounds like a kick drum, scratch, snare, and cowbell by merely tapping your speaker in different places. Control the volume with force, give it a good hit for a loud output or tap gently for a soft sound.
Sony has claimed the battery back up of 24 hours, but in actual usage, there are a lot of restrictions to get that much backup. When you put the volume at 60%, you can get up to 16 hours of battery backup. Also, the speaker comes with a USB port that can be used for charging the smartphone.
If you waste your speaker’s battery to charge your smartphone, then probably you will not get sufficient backup. The speaker takes up to 4 hours to get fully charged. If you turn off the speaker during charging, it takes even less than 4 hours.
Party chain features let you connect up to 100 speakers so that you can make a party chain to create the party atmosphere. NFC is also working fine.
Call quality of speaker excellent. The person from both ends can clearly hear each other. The noise cancellation is also up to mark.
In my opinion, the XB 31 is a perfect Bluetooth speaker with almost all essential features. The speaker is also small as compared to all the remaining speakers from this series. If you need a portable speaker to fill the mid size room with great bass, then go for it.
