ZEBRONICS Astra 35, Portable Bluetooth Speaker, 16 Watts, Upto 8h Backup, Dual Drivers + Dual Passive Radiators, Call Function, Bluetooth v5.3 | USB | mSD| AUX, TWS, RGB LED

Okay, I received this speaker on 17/06/2026 at 70% battery. After using it for 6 days I'm writing this review. Battery Backup: I have used this speaker for 3.5 days (10+ hrs a day) without recharging it after receiving this on an average at 50% volume. So it gave me 30+hrs of battery backup (remember from 70% battery). Charging time is long though it nearly took 6-7hrs to get full charged. But considering the battery backup it's good. Sound quality: Bass : The bass is not very deep or too heavy like boat but the bass is decent good enough for me. Vocals and instruments : vocals and instruments are very clear properly balanced. Loudness: it's very loud at this price range. I didn't expected it to be that loud after watching many review videos but believe me when you will listen to it infront of you, you will understand what I'm trying to say I was also shocked when I played the very 1st song after receiving this In one sentence I can say the sound quality is balanced which is good. It can be compared with a 1200-1500 speaker as well. I'm attaching one combined video of playing different (3) songs and (2) movie scenes on this speaker 2 of them(songs) may be was played at 70% volume and the movie was at 50% volume. My phone's microphone couldn't able to record the sound of the properly, so you can't judge it by only seeing a video you have to experience it by yourself.

I'm not much satisfied but not at all disappointed as well cause at this price this product is offering very loud and good sound, lighting is plus factor as well, not for music cause there is very little bass but I can say it's justifying the price,

Base is decently good, loudness is good, music clarity is amazing, battery backup is tooooo good seriously. I am currently using this as a computer speaker, bluetooth range is also good, connection is stable. 10 different rgb modes and rgb can also be turned off for better battery life. Must buy

Sound quality ok, battery backup ok

Sound not good

Good one in this budget. Sound quality is OK. Battery having good backup, upto 10hrs approx, without LED lights. 1. Not good for call function as the mic is not that much effective and other person will not hear our sound clearly. 2. Main difficulty faced is for switching off the LED lights. There is no one touch OFF. We have long press the button multiple times to switch the lights off. That is the only difficulty I faced. 3. It takes a long to charge the battery completely. There is some disturbances in sound using while charging. 4. There is no hook or space for nail insertion for attaching it to the wall. We have to put it on a table or stand. Rest all ok. Mainly battery backup without light is very good. Getting backup upto 10 hrs approx in a medium volume. I didn't tried with lights.

Nice product

Worked just 15 days. If you want a speaker for a very short duration, then it just gets the job done. I know audio very well and listening to these for the first time felt awful, then I tweaked the equalizer in Poweramp and played it in lower volume, just 30-40% max, never more than that. Then it plays properly. But just worked for a month and unusable now as the music us disappearing every 5 second, perfect trademark of a cheap speaker. So don't know how long it'll last for you, but definitely don't expect anything much. And if you really want good music, skip it and obviously you'll need a speaker that lasts more than a 15-30 days atleast. So try any other cheap speaker. Oh and also I took 2 of them and connected them by TWS which worked beautifully creating a wide soundstage but collapsed in just 15 days. 🤦‍♂️ Have to get something else now.

Its a good product
