Developed by JARRE Technologies and available in a choice of glossy red, glossy white and matte black (my review sample), the Aero Bull Nano is a portable Bluetooth speaker.  To emphasise the portability aspect of this device, a carabineer ring is included in the package.  This allows you to attach the speaker to an article of clothing when you are on your travels and require music on the go.

The speaker’s title gives an indication as to its size and shape.  With regards to the “Nano” aspect, this Bluetooth speaker has dimensions of 85 x 90 x 85 mm (H x W x D).  As to the shape of the speaker, the Aero Bull takes on the appearance of a stylish shades-wearing bull’s head as it delivers the bold JARRE TECHNOLOGIES signature sound. The shades are permanently attached so there is no chance of borrowing them during a sunny period.

This Aero Bull Nano device offers users a  choice of Bluetooth or line-in connectivity depending upon the source of the music being streamed through the JARRE kit.  In most cases Bluetooth will be the preferred option as the Aero Bull Nano will connect to a smartphone or tablet through its support for Bluetooth 4.0.  Establishing a Bluetooth connection between the Aero Bull Nano and various smartphones and tablets in my possession proved straightforward with a blue LED light, located on the left side of the unit’s neck, flashing during the pairing process and then switching to a steady blue glow to indicate a connection was made. A light on the opposite side of the neck indicates when power is being delivered to the speakers..

If your music source does not support Bluetooth then you could use the supplied audio lead to make the necessary connection.  I suppose referring to this supplied lead as merely an audio lead is a bit of a misnomer.  Measuring 46 cm in length, this lead splits into two strands at one end thus giving options for standard USB and 3.5 mm jack connections while the other end has a micro USB connection.  This combination of connections means the same lead can be used to connection a non-Bluetooth aware music source and to recharge the Aero Bull Nano’s internal battery.

According to the information supplied with the Aero Bull Nano, charging the battery for the first time could take up to 12 hours.  To be on the safe side I left the charging to take place over night.  With a fully powered battery you should expect around eight hours of continuous music.  When I tested this feature, I managed just over five hours when using a Bluetooth connection and felt rather short changed by the conversion rate.

Packed into the head of this Bluetooth speaker device are two full range tweeter 18 mm drivers delivering 5w of output plus a 39 mm subwoofer driver that adds a further 5w of output.  While the Aero Bull Nano has a small button on the back of the speaker for power on / off, it does not possess any controls of its own for adjusting the volume level.  If any adjustment is required, as I am sure it will be, then this will need to be carried out by using the controls on whatever device is streaming the audio.

I was impressed with the quality of the audio output delivered by the Aero Bull Nano speaker.  The slight inconvenience of needing to adjust the volume level via the music source (smartphone, tablet or MP3 player) was neither here or there and did not impact on my enjoyment of listening to music from the Aero Bull Nano.  Whatever colour you opt for, this Bluetooth speaker should be available for £79.
