DOCKIN D FINE - thumbnail Test seal: DOCKIN D FINE, Rating good

5th place: DOCKIN D FINE

The price/performance ratio of the DOCKIN D FINE Bluetooth speaker is perfect. For the comparatively low price you get a Bluetooth box with a very good sound. Limitations exist in regard to mobility. With its weight of almost 2kg, the speaker is very heavy and is probably less popular on the go.

6th place: Bose SoundLink Revolve

The Bose SoundLink Revolve Bluetooth Speaker is small in terms of size, but big in terms of sound. The sound is very evenly distributed around the device and is great for this size. However, other larger devices in its price range have a better sound quality. It's perfect for travelling. The speaker is only protected against rain and water splashes and should not be under water for long periods of time.

Ultimate Ears - MEGABOOM 3

Winner: read review
  • It's best to take a charger cable with you. Although the battery life of most devices is very long, it happens quite often that the battery is suddenly empty. Especially after long periods of non-use, the battery may be unexpectedly low.

In the run-up to the test, we defined practical requirements and the following test criteria:

  • Sound quality
  • Functional scope
  • Battery performance
  • Handling

In order to evaluate these criteria, we have defined several tests for the Bluetooth speakers. In order to test the sound quality, the loudspeakers are played with different genres. We pay attention to high tones as well as bass. Each loudspeaker is checked for available connections, apps and included accessories. Devices which, according to the manufacturer, are waterproof or protected against splashing water are tested accordingly. Finally, the battery capacity of all devices is measured.

In order to rule out errors and to ensure the load of everyday use, each test takes place in several runs.

The test criteria receive percentages depending on their importance. The final score is then objectively calculated from the criteria using an algorithm.

Product selection

Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest). Criteria such as price and functionality are an important factor for us.

The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.

As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.

Most recently, Stiftung Warentest (a german, well-known foundation that tests products for consumers) evaluated Bluetooth speakers in January 2019. The Beoplay P6 from B&O was the test winner with a score of 1.7. It is the most expensive speaker and is only pulled down a little by the battery performance. Two loudspeakers land in last place. The Yoyo from Cambridge Audio and Sony's SRS-XB21, both with a 2.9.

19 devices were tested, of which twelve were rated "Good" and seven "Satisfactory". In order to come to this result, the following criteria were included in the grading: Sound (65%), handling (10%), stability (5%) and battery (20%).

For the sound test, the speakers were played with music from the genres pop, techno, classical and also only spoken word (e.g. audio books). The loudspeakers were connected to a smartphone via Bluetooth and to a system via a cable. The sound quality was tested outside and inside by five experts for naturalness, transparency and sound at a greater distance.

In the further course of the test, the instructions for use and commissioning were assessed. Furthermore, the devices were tested for their suitability for everyday use. By examining Bluetooth range, connectivity, source selection and transportability. Especially the transportability of some devices was not convincing, as the unprotected membrane of the speakers could easily be damaged.

In order to test the stability, the Bluetooth loudspeakers were dropped from a height of 0.8 metres onto a wooden floor and showered with water like rain for five minutes before being checked for functionality. All but one of the devices delivered very good results here.

The evaluation of the battery was the biggest problem for many speakers. The battery life decreased rapidly, depending on the volume. Also with the charging duration some devices could not convince - only four could supply a very good result.

The Bluetooth loudspeakers tested by Stiftung Warentest did not overlap with our test devices. However, we tested Sony's SRS-XB31, the successor to Stiftung Warentests loser. The new model scores much better in our test than its predecessor.

Nowadays, countless devices ensure that you can listen to your music at any time and in any place. Laptop, tablet or smartphone - they're all capable of playing music. And with modern Bluetooth speakers, you can even improve acoustics and increase volume. But how do Bluetooth speakers work, what features do they offer, and what do you need to look out for when you buy them?

Those who prefer headphones can also find a Noise Cancelling Headphones test.

What are Bluetooth speakers?

The technology of a Bluetooth loudspeaker is based on short-range radio. This ensures that music files can be transferred to an output medium such as the loudspeaker without a cable connection. The range is limited to a short distance of a few meters. However the advantages of the technology come to the fore, as the corresponding loudspeakers can be positioned freely in the room and their position can be changed within seconds if required.

The Bluetooth technology itself is based on a wireless transmission protocol that can be used to transfer data from one device to another. This makes it possible for music that you play from your smartphone or tablet, for example, to be played through the speakers.

Where you can use your Bluetooth speaker depends primarily on the range. Theoretically, the Bluetooth range should be up to 100 meters. In practice, however, the range is usually smaller due to interference signals or power drops. Nevertheless, a maximum range of around 25 metres is quite realistic for some models, which is why they can be used with great flexibility.

You don't need any further technology to transfer the music files from the smartphone or tablet to the Bluetooth speakers. This is due to the fact that almost all current models nowadays have a Bluetooth chip that is compatible with the speakers.

Many Bluetooth speakers have SD card slots or USB ports in addition to the Bluetooth function for connecting external playback devices. Thanks to them, you don't have to pair a player with your speakers to play music.

To use the Bluetooth speakers with your smartphone, tablet, PC, or laptop, you must first connect both devices. First, make sure your playback device's Bluetooth feature is turned on. Then turn on the same feature on your Bluetooth speaker. This is done by pressing the button on the speaker. Some models require you to press and hold for a few seconds, while others require just a short press. Now the so-called pairing between the two devices takes place. Usually this process only takes a few seconds.

A decisive advantage of Bluetooth speakers is their compactness. They are small and usually weigh only a few hundred grams. This makes them easy to transport and to install almost anywhere. There are also no annoying cables, which makes the Bluetooth loudspeakers much more flexible than conventional loudspeakers with a cable connection.

In addition to their compactness, they have another advantage that is important for playing music. The sound quality is significantly better compared to the sound output of smartphones or tablets. In addition, the maximum volume is also significantly higher. In order to achieve the highest possible playback quality, it is advisable to use Bluetooth speakers with aptX. This compression technology ensures that the quality of the music in audio transmissions does not deteriorate during transmission from the playback device to the loudspeaker.

The main drawback is the security gap that can occur if the device is used improperly. If you enable Bluetooth on your smartphone or tablet, check your settings first. This ensures that no one else can access sensitive data such as pictures, videos, or contact information via Bluetooth.

The short range of Bluetooth technology is also a disadvantage from time to time. Although some models have a range of more than ten meters, the walls in your home can already break the connection.

Bluetooth is a technology that has been around for almost 20 years and was initially used mainly for mobile phones to connect them to each other and enable data exchange. Over the years, the technology has been continually improved, so that many versions of Bluetooth can now be found that differ in their characteristics. While the first versions only differ in terms of transmission speed, later versions also feature improvements in range and power consumption.

The first Bluetooth version 1.0 has a very low range and a transmission speed of only 732 kbps. Bluetooth 1.1 hardly has any updates compared to its predecessor, while Bluetooth 1.2 already has a transmission speed of 1.0 MBit/s. The Bluetooth 1.1 version has a very low range and a transmission speed of only 732 KBit/s. Bluetooth 1.1 hardly has any updates compared to its predecessor, while Bluetooth 1.2 already has a transmission speed of 1.0 MBit/s. The first significant increase in performance was achieved in 2004 with the introduction of Bluetooth 2.0. 2.1 MBit/s represented the highest speed for many years. Not until 2009 did the next version follow in the form of Bluetooth 3.0, with a maximum data rate of 24 Mbps.

However, current Bluetooth speakers no longer work with versions 1 to 3. Bluetooth 4.0 or even 5.0 have long since become the standard. Compared to 3.0, the current versions have many times the transmission speed and range, which means that the technology has meanwhile proven itself and can be used flexibly.

Bluetooth speakers can vary greatly depending on the manufacturer. So there are some aspects you should take into account when buying Bluetooth speakers in order to find the best speaker for your individual needs.

The first criterion for selecting a speaker is its future use. If you want to use the Bluetooth speaker primarily outdoors, for example when camping, the housing should be suitable for that purpose. Important features for this are a robust and dust-resistant housing that is also waterproof. If the loudspeaker is used more at home, an integrated radio function is an advantage. This ensures that you can quickly play music in the bathroom or kitchen. For use in your own four walls, the Bluetooth speaker should also have a docking function. This way, you can significantly optimise the background noise and even use the speakers to improve the TV sound.

There are a few more features that are essential. Long battery life is especially important for outdoor use. The range of functions also plays an important role. Many of the current high-quality models can even do more than just play music. Some have connections for other sound sources that can be connected using a jack cable in addition to a hands-free function. An SD card slot is also an advantage. With an SD card, you can carry your favorite music around without needing an additional music source like your smartphone. Last but not least, a large Bluetooth range is an important indicator. Especially outdoors, a range of at least eight meters is very convenient. However, this range is only given if the Bluetooth speakers of your choice have at least version 4.0, or even better 5.0. When you buy a Bluetooth speaker, make sure that it meets the latest standards. Otherwise, data transfer and range could be too small to enjoy all the benefits of Bluetooth speakers.

It's also important to take a close look at the model of your choice before you buy. Speakers with Bluetooth capability are not always wireless. Although some models don't actually require a cable connection to the player, they still need to be plugged into a wall outlet to be powered.
