Blaupunkt Atomik BB20 Wireless Bluetooth Party Speaker 20W with Dual Passive Radiator I 1500mAh Battery I Deep Bass I Karaoke with Mic I USB I TWS…

The sound quality and built is good. The battery drains after full charge even when not in use.

Nice & clear sound just i purchased for my keyboard 🎹 outdoor use It will serve as per my requirement battery 🔋 is good, karoke mode 📳 is nice good to carry..

It’s a total waste of money. First drawback is the charging cable acts as it’s radio antenna, so either you can charge or play radio. If the battery discharged during playing radio one has to put off the radio and plug in to charge. Next – The quality of charging cable cum radio antenna is so fragile that it easily comes out (see pictures) even with careful usage and an accidental very slight pull. I have never seen this weak material in any other brand of Bluetooth speaker or mobile or any device.
Moreover, spare charging cables are not available in the local market in all major cities. I am from the capital city of Odisha, still I have no access to a Blaupunkt showroom or any local dealers who sell Blaupunkt charging cable. The design of the port is such that any other cable is not compatible with this instrument.
Now the only option is Blaupunkt customer care. They were kind enough to send me another cable free of charge but still that didn’t work so they agreed to take my instrument back and send me another piece. And guess what! Even the new instrument cable came out within 3-4 time usage without any major accident. Just that I was playing radio on the Bluetooth speaker on bed with antenna (charging cable spread out to catch clear signal) , and my daughter roller on the bed, slightly causing a pull on the cable and see the picture, how it came out! Unbelievable isn’t it? Has anyone seen such a fragile material for such application?
I request one and all not to buy this product 🙏

 I am reviewing after one week of daily usage. When I opened the box, I realized the brand value by good quality package and neatly packed and protected contents. After powering ON and playing my first song on it, I recalled my HMV Vinyl Player that I owned in 1988. Extremely crisp high and mid frequencies from high fidelity speakers; you can feel that the song is played outside the speakers (and not deep inside like other bluetooth players), as was evident in the Vinyl players. The max volume is so much high (when pushing up the volumes of both this device and the mobile/laptop) that human conversations in the room will be almost cancelled (inaudible). This again reminded me of my HMV Vinyl player. I tried to sense its stereo effects in the songs having different frequencies in two channels (like, Om Shanti Om by Kishore Kumar, Film Karz). All the separated frequencies are clearly audible (which are suppressed in mono amplifiers). Yes, the channel separation cannot be felt as the speakers are too close and their audios are overlapping. This is because of the small size of this equipment. It is very portal (length is just one inch extra of my stretched palm; width and height are four inches each). hence, the size shown in the pictures is not correct as they make this equipment appear much bigger. However, this is not a concern for me; rather it is a good thing given its audio quality.

Now I come to Bass. I am a Bass lover, but may have a different definition. My definition of bass is: the bass guitar melody/scale changes, the bass-drum, the bass trumpet, the piano bass, and the bass unit of African Congo/Bongo are audible clearly. I do not consider the modern “Deep House Boom Boom” as bass because it is more of a low frequency noise with no musical expression. With my definition of bass, it is amazing in this device. All the old songs of 70s, 80s, and 90s will sound amazing in the bass zone. In fact you cannot get this level of bass clarity in modern bluetooth speakers because of passive amplification (using passive bass radiators instead of active drivers in speakers). This device has active amplification in both the front speakers although a small passive bass radiator is also provided in the rear (this is the reason, the boom boom is felt in the back or else when you keep it close to a vertical wooden surface; such as your bed wall). In the front speakers the bass is audible as per my definition even at 10% volume (the passive bass radiators trigger bass only after 25% volume as they require air pressure from the sounds to trigger their vibrations).

Now I shall cover the physical build. There is no match to wooden speaker boxes. The plastics make the sound boxy and quite enclosed. All my earlier amplifiers have wooden speaker boxes. Blaupunkt knows this fact clearly and hence have provided hard plastic alloy body almost as strong and heavy as wood.

The FM radio and microphone are added features of this amplifier. FM works very well. You just need to connect the power cable as antenna (without plugging the power adaptor) and tune the FM channels once by pressing the play-pause button long. The mic is moderate. There is echo without any controller. It could be better to provide an echo controller. However, it sounds good if you hold the mic three to four inches away while singing. I have tested all my expensive mics. Overall, this feature is quite satisfactory.

That’s all from my side. I want to conclude by saying that you will enjoy this speaker only if you are a music and melody lover. The rap or non-melody lovers will not enjoy it as they will find all their favorite bumbles, booms, blasts (and all such noises except music) missing in this speaker.

P.S: Please hear sound of attached video in good bass headphones;
