Astrum SoundBox ST150 Review – The best pocket speaker ?

Atrum SoundBox ST150

Hello everyone, Astrum actually requires a bit of the introduction to you, but not if you already followed me here. I have earlier reviewed their Bluetooth Headphones you can check it out here. Astrum HT600 did impress me and I didn’t expect it to turn good. Earlier on this site, I reviewed the SoundBot SB572 Bluetooth Speaker which is too awesome at battery life. The Astrum Soundbox ST150 when we were supposed to receive it, We thought to compare it with the Soundbot. When we unboxed the speakers I thought they shouldn’t be compared to it. It’s because Astrum SoundBox ST150 is unique of its own kind and possibly you will love it as a unique Bluetooth speaker.

Build of Astrum ST150

When I unboxed the speaker I’m still in shock to see its small form factor. It is indeed the smallest and the premium feel speaker I have come across in the span of my tech reviewing journey at that price. A rectangular shape Bluetooth speaker which fits in any hand for sure. Astrum S150 has a huge metal rim at the sides, the rear has the clean leather type finishing with the embossed Astrum logo. The front has the speaker grill with 3 small speaker drivers. On the metal rim at the top has the MicroUSB charging port with the power On/Off button. To be precise about the size it was slightly larger to fit in my palm but with my fingers, I was able to get the grip of the speaker in a much better way. It’s the only powerful speaker which will fit in your jeans back/ front pocket easily and you might not worry.

No need of carrying case as your pocket itself is the best carrying case for this speakers. I would rate the build 8 out of 10, It doesn’t have aux/card slot like the others does but fitting the aux port and card slot in such small form factor is much tuff game for Astrum. They already have done good in others part so it’s negligible.

The sound of the Astrum ST150

I need to say you might directly jump to this section because this is the limelight of the all the Bluetooth speaker’s post. I really thought as they are the small speaker they won’t sound as loud as we have seen the SoundBot SB572. The Astrum did shock us with its loud voice. I’m still shocked when it play super loud for the room. Trust me, you won’t believe the sound output of this speakers. The speaker is equipped with good base and trebles. It’s small but not less powerful. The sound levels were more than adequate, it’s didn’t had the perfect detail for the audiophile but I won’t complain that looking at the price point. There are 2 32mm speakers which show the sound and the middle one is the vibrating motor which works as per the sound.

Overall I will rate the sound at 7.5 out of 10.

Battery life

If you read the specification above then you would know this speaker has 700 mAh Li-ion battery. In our test at complete rundown from 100 percent, it did last for 3 and half hours. In charging over with normal 5V 1A adapter it did take somewhere around 2 hours for the complete charge when they where completely drain. The standby time for the speakers is completely good.


The MRP for which the speakers retail is at Rs. 2790/- you might get it for cheap over online portals. I will definitely say it’s totally justice to the price. It doesn’t come with volume control but you can control the volume via your phone volume rocker and that’s the only way. I think that’s still an Okay way. Astrum did really make it different with this speakers for sure.
