The media could not be loaded.  I am writing this review after using this speaker for more than 3-4month, it's actually a very beautiful and superb speaker with the perfect sound quality and battery is decent, after charging once I use this speaker for more then 7-8hrs a day still it works 2-3 days very easily which is the best part of this speaker, sound is also so much good, so the conclusion is if you want a best Bluetooth speaker with good sound quality with good playtime and also with good connectivity in this range, then it's a perfect choice go for it..!

I was happy to receive the SonoTrix 51 bluetooth speaker. Amazon delivery was excellent.Updated review: 14th January 2022: I found a way to fix the bass issue. Using a equaliser app on my phone I reduced the bass to about 60% for all music output on my phone. Now the speaker is working really well even at higher volumes. I'm happy with the SonoTrix 51. Thank you, Quantum Hi-Tech!Initially the sound and bass output was very good considering that it is only a 5W speaker. But since the last one week I have noticed that the speaker is emitting a broken sound for lower frequencies. With the bulk of my songs played from YouTube, the bass drum sounds completely shattered! One solution is to play stuff at a lower volume if you don't want to cringe at the unexpected. Otherwise it's a quality product and value for money. I wish I could have given 5 stars. You might want to order the SonoTrix 8W instead and see if it handles the lower end better.

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

The first one that got delivered was faulty, was promptly replaced by Amazon, great service!Speaker is decently loud, as you would expect from a 5 watt speaker. As with most bluetooth speakers, sound through AUX cable decreases, so does the sound effects (bass n all).The speaker is bass heavy but it's not the boomy bass, it's muddy. The bass radiator rattles at high volume and it becomes unpleasant. Above 70% volume, sound quality completely goes for the toss.Vocals are not clear, treble and mid range is terrible, this is like those cheap earbuds that only focus on bass and do not care about the sound quality. Instrument separation is terrible as well.Battery backup is good, the speaker is built well, buttons are clicky but it's unnecessarily big and bulky.Problem with these Chinese rebranded items is they tend to provide a bigger bass radiator than the speaker itself, size should be in 1:1 ratio.Better options: Florid star (Rs.499) Mivi Play (Rs.699) Mivi Roam 2(Rs.799) Boat Stone 180/190(Rs.799-999), Boat Grenade(Rs.999-1299).Best Alternative: Infinity Fuze 90/100 (Rs.999)Infinity's sound signature and bass is on another level.

I purchased it in last day. The speaker is good working very well. Audio quality is good. It's little bit heavy. Looks like premium. But no dust proof. Overall good with this price range. There is no discussing sound like your device is ready to connect or connected(like boat speakers). That's the first thing i like here. I was using jbl on the go that's much better but it has an additional feature that's is usb support amd battery life.Very good battery life till have 90% of battery after playing music more than two hours with 70% volume. But charging time is high 7hrs and there is no indication like green lite if its fully charged.

Well , Probably no body has frustrated me like this Product . Looking into the product , it was a made in india, which is why i choose this product and after seeing the good reviews . I was excited to receive the product , and just after 10 days of very limited use the product stopped working . The Product is not getting powered up . I tried putting on a charge for long hours still the same . With the hope that I will be easily able to replace the product and good service as this comes with 1 year warantty . I tried reaching to amazon , seller , and then i was introduced to the harsh reality on this product that amazon does have any clue on whom should i contact for a replacement or service and kept on giving me wrong information for 20 days . Now Somehow I am able to connect to the company directly , they are asking me to go ahead and get the waraty claimed from a place which is very remote and not at all feasible . For mere 600 rupees there is an additional headache with replacement. Call center is callus , service center is callus , these sellers I think are buying the reviews and it is a worst company . The purpose of putting this detailed review is that , other people should not get fooled by this hooligans'. Please go for better brands rather then spending money on there cheap delhi brands . You are surely going to repent . I have left all the hope , i am to tired to run . Thanks .

Recommended for everyone sound quality also premium

Valur for money product.
