First impression to Bluedio US
Delivery
Bluedio is known for including a wide range of accessories with its audio products. With this Bluetooth speaker, too, all accessory options have been exhausted. In addition to a multilingual user manual, it also includes a USB charging cable, a 3.5mm audio cable and even a carrying strap with a carabiner.
Original Bluedio
The authenticity of the loudspeaker can be checked using a code on the back of the packaging. There is an authenticity seal with a code that can be scratched off. A link that leads to the Bluedio homepage can then be used to check whether it is actually an original Bluedio loudspeaker.
Design and workmanship
The most outstanding feature of the Bluedio US is the design. The name “UFO” already indicates the speaker’s spacey appearance. In the middle is a 59mm bass driver. The side arms or wings consist of two 40mm drivers. The 310 x 170 x 105 mm loudspeaker can be placed upright and, as standard, on the anti-slip pads on the underside of the wings.
The workmanship of Bluedio US (UFO) is good. The housing part, which shines so beautifully on the pictures, is not made of plastic, but actually made of metal. With rich 921g, the Bluedio US speaker is anything but a lightweight. The black housing part is made of plastic, but is still very well matched to the metal part and also processed properly. Only the plastic control buttons and the adjacent LEDs could be better matched to the rest of the housing.
Commissioning & functions
Anyone who has ever put a Bluetooth speaker into operation, will also get no problems with the Bluedio US (UFO). In pairing mode, the speaker can be easily and without password input connected to a compatible Bluetooth playback device. The enclosed operating instructions describe in detail the commissioning, operation and also individual functions.
A bluetooth speaker should be able to play music. The Bluedio US can receive music via Bluetooth (A2DP), but also via a 3.5mm audio input. In addition to playing music, the loudspeaker can also be used to accept and make phone calls (HSP, HFP) from a connected smartphone. For this purpose, there is a small microphone below the control buttons, which enables the hands-free function.
The most interesting feature is the 3D mode. This can be activated at the push of a button and produces a more voluminous sound. More on how the loudspeaker sounds in the next point.
Klang
In normal mode, the sound of the Bluedio US (UFO) appears neutral and low in bass. The sound could be described as almost unspectacular if you mostly like bass-rich music. The speaker experiences a real bass and sound boost with active 3D mode. Only in this mode does the 59mm bass driver (5W) really come into its own. Music sounds significantly more voluminous and a certain spatial sound is actually created. The two 40mm (5W) drivers also appear more dynamic and warmer. In a direct comparison with the Bluedio AS loudspeaker - which also has a 3D mode - you can clearly see that the Bluedio US (UFO) has significantly more powerful loudspeakers and the sound is better coordinated overall.
The maximum volume is also impressive. A scratching or shouting has not made itself felt in even the most shrill and bass-rich music. Only the mids and heights are somewhat lost due to the increasing volume. There are sound differences depending on whether the speaker is connected via the 3.5mm audio connection or via Bluetooth. In the cable network, the control buttons are obsolete and the speaker is used purely passive. The powerful 3D mode can not be activated then. Wireless is the maximum transmission range at well 15 meters.
Rechargeable battery
Bluedio does not provide any information on the type or capacity of the battery. The battery cannot be changed. The manufacturer only specifies the running time as up to 5 hours. In practice, the 7 hours are very long and can only be reached with a low volume. A value of around 4 hours with normal volume and an active Bluetooth connection is realistic. Two LEDs serve as a charging indicator. If the loudspeaker is connected to the power, a red LED indicates the current charging process. When the loudspeaker is fully charged, a blue LED indicates that the battery is fully charged. A full battery charge took 4 hours in the test.
