QuantumSonoTrix 51 Bluetooth Speaker, IPX7 Waterproof, TWS function, 5W, Powerful Bass, BT 5.0, Upto 19hrs Playtime*, TF/SD Card Slot, AUX Input, USB Support and in-Built Noise Cancelling Mic (Black)

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.

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.

Pros:1. Sounds like more than 5w, enough for small treats, get togethers2. Quality of sound is good below 70% of the volume, later voices just shouts3. IP rating makes portable4. Battery back up is good5. Sturdy built quality6. More connection options7. Latest Bluetooth tech. But range is same 10m.bought @₹700Cons:1. Aux cable could have been provided.2. No fast charging3. Backup is good but charging time is also long

The Bass is discernible but mild. The mids are a bit muddy, but not to the point of affecting clarity. The highs are clear. Volume is decent. At this price point obviously the audiophile in you won't be satisfied. But what you do get is a quick connecting long lasting speaker that works great. One charge lasts more than a week if your daily listening time is less than 2 hrs. Remember this is not a party speaker. It's just meant to be used when the speakers on your phone/laptop are not enough. And for that it's brilliant.Also, prompt delivery by Amazon.

I enjoy high volume music while bathing. Don't waste your time in reading reviews just go for it.
