The media could not be loaded. 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;

Truly the product is worth more the it's cost. Sounds very good, bass is great...and the functionalities can't be compare with any other brand. You won't regret it.

Good for a room size, decent bass,tribble and loudness is enough. Bass is not punchy but it's going d for a 20w than choosing 10w.mic good quality.baterry backup is only for 1 hr. Frequency breaking in lower and heigher band. Not been designed best.Replacement period gone, it's difficult to get from dealers.After a year. Battery dead. Nonreplacmenet by anyone,no serviceCan open box by serviceman.Poorest quality

The media could not be loaded. I should say this is an outstanding Bluetooth speaker with FM. You can connect your mobiles, laptops and other audio sources through bluetooth to this speaker, volume is amplified, clarity is good, and bluetooth connectivity is outstanding...They provide a microphone also with this to do karaoke and you can I guess speak to an audience in a hall and whatever you speak will be loudly audible to the audience, although I have not tried this yet. FM is also present, if you short press power button FM starts and auto searches stations. Long press of + and - Volume control buttons help in increasing and reducing the volume whereas sort press moves the audio to the next and previous songs while not using FM but mp3s or other audios. While using FM these buttons help in changing stations. Charging is fast, and battery longs last, they claim it to last for 12 hours if continuously used, I guess this is true as I have not timed it, but battery is long-lasting I am convinced. You can also insert a microSD card containing audios and listen to them and navigate through the songs easily using the volume control buttons.It is a good device that can be purchased to have a nice time in a melodious way. Its a treat for music lovers. Students can also use it to listen to educational videos while doing daily chores like brushing, cleaning room, washing utensils, cooking etc and save time better and multitask as I do.I even felt that it could be a good gift to elders who listen to bhajans and other devotional songs after retirement...Finally I would like to conclude that this is not just a Bluetooth speaker, but an outstanding Bluetooth speaker which provides quality and features which is worth more than the price it costs. And Amazon has brought it to us with great discounts which requires no praise. Its a default feature of Amazon...Blaupunkt is going to move higher in the audio industry I am sure if they continue producing such quality devices...I think its already a brand and its a German company with values and best products...Service issues and customer care is also good and response is fast and timely....Hope all the goodness continues for a long period, it may as they provide a warranty also...Thanks Blaupunkt and Amazon..You gave us a few more happy moments in our lives...

This review is written after 1 year of usage.The sound is decent. I expected better from something which is branded as the "Hallmark of German Engineering". My Lenovo Thinkpad speakers have better clarity and quality. The voice lacks natural bass and sounds flat with mic.Battery lasts ~3 hours. From yesterday, charging has stopped working suddenly. Tired multiple chargers and cables.Better than unbranded options.
