QuantumSONOTRIX 51 Bluetooth Speaker, 5W Sound, TWS Mode, Powerful Bass, IPX7 Waterproof, 19hrs Playtime, MicroSD Card, AUX and USB Input Support and Noise Cancelling Mic, 1-Year Warranty (Blue)

It is very nice product at the price I must say ₹699Bass and treble and volume is nice but in noisy environment volume sounds low may be because of generates bass from air.It is thicker then I expected so it is not portable though it is small in length and width.Battery is nice. I have not done stress teating but it didn't die out atleast for 8 hours at I think 90% volume which for me is more than enough.Have not risked to test IPX7 rating yet as I would like to make good use rather than entering into warranty issues later on

I totally like itIts Bluetooth connectivity is good and it works very well

It's a good product undoubtedly.Battery Backup - haven't charged it yet since It came. Still working. Have used it for more than 10 hours till now.Sound - it's crisp and punchy . Quality is OK in full volume as well.Build - Sturdy and feels good in hand.One Problem I have seen is that the sound output is considerably low with iPhone than with Android on Bluetooth.Not sure if its with me only.Those who are confused between 51 and Mivi, well 51 output is more. Mivi is good, but if you are looking for loudness then go for 51.Rest you can use and see.Update -Buttons stopped working after 1 month.Customer Service is bad.No home pickup and drop.You will have to visit service center. There also it will take 10-15 days for replacement.Not sure when I will receive my replacement.

Recieved my sonotrix 51 and after listening to it for a hour. I found following conclusions, this product can really give competition to bigger brands and at a great price.Its not one of the loudest of the speakers, but the bass output and clarity in the vocals and the background instrument is fabulous.It is not one of the speaker after hearing instantly you will say wow!! Its one of the speakers the more the song you hear the more you will get fond of it.Overall a superb product compared to the price..good job team

Here is my reviewPros - micro sd card slot- usb port- aux- Sturdy built- waterproof- good battery on Bluetooth- call and mute functionCons- not good audio quality- lacks bass- lacks audio clearity- volume is average- A bit heavier- With certain phones this speaker sounds a bit lower than usual sound qualityWHO SHOULD BUY THIS?- you are on budget and wants a waterproof bluetooth speaker with different types of connectivity available along with descent looks- you are a student and looking for online class wireless speaker- you workout and dont want to bother about the safety of speaker outdoors- you already have another better branded speaker, you just want it to be your secondary speaker.Not recommended if you have budget over 1000 rupees. Buy it when its on deal.NOT RECOMMENDED IF you want good music output and clear hd sound with bass.
