Overview of our technologies
The BOOMSTER is one of the best-sounding Bluetooth radios in its price class. You can expect pure sound from this portable stereo speaker with plenty of boom thanks to the following features:
- A separate downfire subwoofer reproduces the lowest frequencies and ensures a solid, punchy bass with electronic music. Subwoofer levels can be adjusted.
- A class D amplifier with 38 watt maximum power performance fires the 5 drivers for especially high and noise-free levels
- A sophisticated 3-way stereo system creates a broad and highly detailed soundstage that fills even larger rooms
- Two tweeters reproduce even the finest acoustic nuances for a clear, engaging sound
- Two midrange drivers endow instruments and voices with warmth as well as power
With the BOOMTER, it’s easy to stream music from smartphones and tablets. Bluetooth 4.0 guarantees a stable wireless connection that's capable of producing high-definition, high-end sound. A range of at least 10 meters ensures flexibility. Even movie sound is reproduced synchronously.
The BOOMSTER comes with high-capacity lithium ion battery with a 10 hr runtime at normal voumes that fully charges within 3 hours from an available power source. If there is no power supply available, the rechargable battery can be removed and standard AA batteries inserted – perfect for longer camping trips.
A 3.5 mm stereo jack socket allows you to connect devices per cable for the maximum level of connectivity with external source devices that aren’t Bluetooth enabled.
The Boomster‘s highly sensitive tuner and wire antennae ensure that even the even the weakest signals come in loud and clear. When it’s not in use, the wire antennae can be easily rolled up and stowed inside a dedicated compartment in the system. Three station buttons allow you to save your favourite stations.
An integrated microphone makes it possible to use the system's Bluetooth function to make phone calls via your smartphone while keeping your hands free. If you’re listening to music on the BOOMSTER, it will automatically shut off when you receive a call. Calls are accepted directly on the device.
The BOOMSTER is the perfect music system for camping or a garden party: Major functions on the BOOMSTER are controlled by discrete touch buttons that allow the surface to be easily wiped clean, and the inputs are protected with rubber covers. The entire construction is incredibly robust and includes a practical carry handle along with sturdy metal grilles over the drivers.
The BOOMSTER radiates good sound and high-quality workmanship in equal measure. A robust brushed aluminium carry handle, thick-walled synthetic enclosure and strong metal grilles give the BOOMSTER is solid look and feel. Simple matte black lacquer with high-gloss accents underscore the system's classic look. Well thought-out details include touch buttons discreetly illuminated in white and an elegantly angled front.

"In spite of its spartan design, the BOOMSTER has a few special effects to offer. A USB port makes it possible to misappropriate the device as a power source for smartphones and tablets. It can be used as a speakerphone via an integrated microphone – the music is automatically interrupted during incoming calls. Thanks to NFC technology, smartphones can be connected to the BOOMSTER with lightning speed.”
"Teufel’s beamed the mobile sound system out of the past into the present day and made it fit for the future. The BOOMSTER is an eye-catcher and attention-getter for inside and out.”

Remember the Boombox? The iconic stereo system that you could take with you on the road and which was also often visible in 80's movies: Teufel reinvented this concept with the addition of some modern day technique. With this transforming one of the most iconic items of the 80's into an icon of 2015.
The Boomster is a Bluetooth speaker that can be used in combination with your Smartphone, PC, Mac or Tablet for listening to music. At first sight the packaging of the product looks impressive and well designed, containing a manual and power adapter along with the speaker.
Also aesthetically an impressive item: the speaker has a handle, which is very practical, and does not weigh remarkably light, given the built-in hardware: 3.35 kg. [...] As one can see from the picture, the design looks very impressive, one of Teufel's stronger items.
Ok, this Boomster looks perfect design-wise, but how does is actually sound? This of course being the most important question, given it's technical specifications. Teufel has done it's homework and therefor the Boomster offers everything you need to enjoy a high quality sound. [...]
Teufel's Boomster is a matter of high quality. We did not experience any particular errors in testing the speaker at any level. The speaker encounters some difficulties at a higher volume, but in general it isn't worth the mention. [...] certainly not a cheap speaker, but bear in mind it is a top product."

Test score: good (2.14)
The BOOMSTER won first place in a comparison test of 20 Bluetooth loudspeakers

"Considering the extraordinarily good sound quality, one should consider the price Teufel is asking for the Boomster to be very fair.“

"The Boomster not only comes with sensible, practical features, it’s a cut way above in terms of sound. Most speakers hit their limits when they have to supply a small party with music. [...] The Boomster perfectly masters this task. The music is reproduced with clarity and precision without disturbing the entertainment or vanishing into the cacophony of voices.
In any case, the loudspeaker completely won us over: The sophisticated 3-way stereo system ensures a broad, detailed sound. Two tweeters reproduce sound down to the finest detail and emit a clear, open tone. Two midrange drivers ensure warmth and power with voices and instruments. A separate downfire subwoofer reproduces the lowest frequencies and ensures a hard, powerful bass without a trace of tinny sound. The subwoofer level can be directly regulated on the subwoofer and allows the Boomster to sound round and balanced or bassy and powerful according to one’s choice. Whether 40 people sit in a large room or single person in a small room, the handy Teufel device is completely reliable. It ensures a powerful, confident and utterly perfect sound in every situation.“
"The Boomster scores points with a nuanced sound quality, modern technology and absolute independence. According to the volume and function, the rechargeable battery lasts up to 20 hours and can be extended with disposable batteries. This is simply unbeatable. The sound is room-filling and harmonious with detailed highs as well as rich bass. The execution is sturdy, the design elegant and controls extremely simple. Those who love technology but also ‘amateurs’ will really get their money’s worth.”

"The Boomster’s sound is very strong for a loudspeaker of this size. Two midrange drivers, two tweeters and a subwoofer serve as the basis for the 3-way system. The subwoofer in particular puts other comparable speakers in their places. The bass is well defined and is energetically played back.”
"The two midrgange drivers and two tweeters likewise do perform their jobs well and indulged our ears with very realistic mids and clear highs.”
"The Boomster possesses the qualities that allow it to present itself as the successor to the ghetto blaster. [...] Thanks to its well thought out 3-way system, it reproduces music with the utmost power and dynamism and does so with extremely stable levels.“

"According to the manufacturer, [the Boomster] should last up to 16 hours at normal volume with both the rechargeable as well as the disposable batteries. We extensively tested the rechargeable battery and ran the Boomster [...] at a normal volume (approx.. 70%) with a Bluetooth connection. [T]he Boomster ran and ran and ran… At the end, [...] [it] stopped after 21 hours which is quite an achievement for a portable Bluetooth speaker."
"The Boomster lived up to its name and set itself apart from the soundstage we have become accustomed to. The sound doesn’t give much hint that one is dealing with a portable Bluetooth speaker, but rather reminds one much more of a full-fledged compact stereo system."
"The entire construction with the downwards facing subwoofer generates a bass that is played back with confidence and stable levels and is always good for a new surprise. An overexertion of the bass membrane that can be detected in the form of a buzzing sound was nearly impossible to produce at any volume.”
"It’s a lot of fun to listen to music with the Boomster. The little powerhouse can really be surprising in many respects. Its size alone distinguishes it from typical, well-known mobile loudspeakers and it can definitely compete with a standard compact system.”

"The effects – no matter in what is played – allow the Boomster to extend deep into the listening room and develop a surprisingly intense three-dimensionality."
"It should be especially emphasized that the compact device is suitable as an introductory system in student dorms or apartments. At the same time, one can be mobile thanks to the battery operation. […] The sound is rich and commanding in a way that one is not accustomed to from such a device."
"The integrated 3-way system [...] guarantees a solid, technical basis that is markedly more elaborate than that which can be found in most competing products."
"Powerful, composed and homogenous – this is how the Boomster tackles challenges. It never seems to overexert itself. On the contrary: One catches oneself constantly using the very responsive touch keys for regulating the volume [...]. "
"This was a coup. We can’t think of another portable loudspeaker that can keep up with the Teufel Boomster acoustically. It plays with power and three-dimensionality, sounds harmonious and pleasant. [...] The newcomer also shows its ascendancy with excellent level stability and flexible portable use scenarios. [...] With a technically sophisticated construction and robust workmanship, it would be hard to find any weak spots.”
"On balance, the Boomster rocks the entire market – more sound and flexibility are not available at the present time."
"„‘We will rock you‘ – Teufel’s Boomster rises to the top from the very beginning.”

"The controls are simple, well thought out and give access to all the required settings in order to enjoy music outside of one’s own four walls. Measured against the loudspeaker’s size, the quality of the playback in the highs and mids is clear and not overwrought. The subwoofer is capable of enormous depths. We really appreciated the ability to supply the subwoofer with a bigger or smaller challenge by adjusting the intensity. This gives the buyer the ability to determine individual settings.”

"With the BOOMSTER, Teufel’s brought a truly amazing product that offers amazing quality to the market – the sound as well as the workmanship. It’s not only good for outdoor use, but also for indoors.”

"Now for the most essential part: The sound. Teufel’s BOOMSTER is a full-fledged 2.1 stereo sound system with a maximum power capacity of 38 watts across 5 drivers (1 subwoofer, 2 tweeters and 2 midrange)! In other words: A lot for such a small device which ensures plenty of oomph. The frequency range extends from 50 Hz to 20 kHz thereby covering the range of larger speakers with substantially more volume.”
"In terms of sound, one can expect more from the BOOMSTER than its appearance would indicate. An integrated downfire subwoofer ensures the right intensity and is paired with well-defined mids and clear highs. Teufel’s BOOMSTER is surely no loudspeaker for highly critical listeners, but it’s one that is a lot of fun and simply sounds good.”
"In terms of music, we can recommend the Teufel BOOMSTER for any genre. Whether pop, rock, electro, jazz, house, rap or R&B, the BOOMSTER feels at home with them all.”
"All-in-all, the Teufel BOOMSTER left us with an enduring positive impression. The looks are good, it’s technologically well equipped, long-playing and - last but not least - was able to make a good impression with its sound.”
