Best party speaker at this price…
Mind blowing product at this price range. I purchase it at 7398 rs in Diwali festival sale. I think at this price range, no other product comes with 120W speaker and basslike this speaker. Prons- 1. bass - 5 /5 2. FM - 4 /5 as you need to attached aux cable for proper functionality. 3. Speaker built quality- 5 /5 4. Karakore light- 5/5 Battery performance- 4/5 5. Mic - 5/5 Cons- When you turned on speaker it speaks zebronics name too loudly and this sound could not be adjustable.

Very nice party Box.
Sound quality is overall okay but the bass effect is not that good. And the vocal tone down feature that Zebronics has given in roxor pro is not there in this. I think if they had given those features in this as well, it would have been better, other wise this price point the sound box is very nice. I am happy with this product ☺️. Thank you amazon for this price point party box.🥳

Bad product. Went duff within 2 months. Dealing with Zebronics is a nightmare
Zebthump 700 speaker bought online video bill no SDEG-54347 dated 09 Jun 25 has stopped responding to charge. The speaker doesn't respond until it is on charge for no less than 14 hours and then plays for approx 5 minutes. Then freezes again indicating no charge. Their is no response even while the charging port is connected and switched on. Details of bill and product serial number are attached. 2. The item has been checked by your technical team, from Janakpuri service centre came on 20 Aug 25 after relentless follow up on calls and social media. He however, indicated that everything is fine and this speaker plays for about 1 hr after full charge as against the recorded 6-7 hrs in your brochure. However he offered no support for the no charging and freezing issue. The speaker played for 5 minutes after he left and froze again. 3. Another complaint has been lodged today by myslef and shall do that untill this is resolved. 4. I would also like to remind zebronics that on delivery the speaker was delivered without the accessory charging cable which I had to seek from zebronics. The speaker was lying unused for the duration from delivery to the delivery of charging cable. 6. These issues don't speak well of a #makeinindia product in the current times. 7. Expecting a positive response from Zebronics to this issue as the item is under warranty. Shall follow up on email again if tbe matter is not resolved favourable until further legal recourse is resorted to.

Good product but bad default volume levels for home use
Good product. Good audio quality when playing via bluetooth. While mic quality is avg, it's decent to use the karaoke mode. Things that annoying and surely needs a fix from the manufacturer 1. Default audio output (at vol level 1) is very high for FM mode. It's very loud for home usage as you cannot even converse when FM is playing. It gets very noisy especially when advertisements are on. 2. The sound when switching between modes like BT ->Aux ->fm and when it connects to BT source is very loud and screechy While we can somehow manage with #2. #1 is very annoying and literally makes the FM feature in this product unusable if you buy the product for home usage. I raised a tech complaint for #2, and there was a prompt response from tech team who even visited the home to check the product. They say they are aware if this but can't fix it since it needs to come from the manufacturer as a firmware update. And apparently the manufacturer needs a lot of complainta to act on it. I find this a very silly and bad customer/product support from Zebronics. This is one of the few products in this category having FM feature and hence I bought this. But this product default volume config defect, FM feature is unusable for home setup. May be ok if you want to play in outdoor Street events. Then the product feature should be clearly mentioned that it's not good for home use.

Good product
Bought this to our school. Delivered on 12-08-25 And it failed within few hours of working. Inspite of warning reveiws , i trusted Zabroinics and bought this Thump 700 by paying Rs, 11,000. Display is not coming, battery is not working. No direct replacemnet or return option. I logged a complaint with Zabronics , (which is cumbersome), seems technician will visit within 4 -5 working days. God only knows how many days it will take to make it working. The speaker was delivered with a poor battery . Now will end up with repaired item/battery. Update: Technician from Zabronics visited and replaced the battery with a new one. He was very helpful and explained about the product well. Upgrading the rating to 4, based on performance of the speaker and service
