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

I m using it with only Bluetooth feature as both Pendrive not working.
In the beginning..it gives you instruction that fm is on ,external media connected like this.
But stopped in 3-4 monthly..it’s just Bluetooth speaker

lets see how long it
lasts

 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;

Good product at the price. Gave only 3 stars bcoz of three issues.
FM radio does not have a visible channel selector. So you may have to keep shooting arrows in the dark to search your preferred broadcast
Secondly the bass is not up to the mark.
Thirdly the Mike has constant echo by default. Makes it almost useless.
