The speaker can be fed with all current audio sources. In addition to the popular variant to pair the mobile phone via Bluetooth to the speakers, but also an operation on a USB drive, SD (or TransFlash) card or universal AUX input is possible. The Rocketbox really having enough input options. The manufacturer must present in a chic white AUX cable, so this does not have to be additionally procured.
I'm not a guy who feels like a long time to read manuals and luckily worked commissioning intuitively in under 4 minutes. About the menu that appears legible in blue-lit Dislay, can easily activate the Blutetooth. It then appears in the My Bluetooth Places Search in the mobile Rocketbox which can then easily connect. A short sound acknowledged the connection and away you go.
The sound of Rocketbox I find good and loud enough. Bass lovers can of course not punchy bass volume can be expected.The at Bluetooth pairing both on the device (long press the "Forward" or "back" - button) are regulated and over the sound up / down keys on the phone. Interestingly, it is possible for example in the Amazon music streaming app, press the title of jump back in front / button on the Rocketbox to change.
Also incorporated is a normal FM radio. This worked well and with the standard channels in the region there were no reception problems.
The Rocketbox can be either via a USB cable to operate (DC 5V) and load as well as on battery power. The supplied battery has a 700mAh and should provide listening pleasure for a sufficient number of hours. The manufacturer uses here a very consumer-friendly solution, the battery type BL-5B is a widespread universal battery, known from many Nokia phones. In case of loss or decrease in performance a replacement is not a problem, you get the batteries for under 10 euros.
The Rocketbox is available in 4 colors: green, blue, black and white. I opted for the white / silver variant, since this comes across very classy. Due to the good processing the good piece looks really classy. In operation, a red LED lights behind the grille, an active Bluetooth connection is also indicated by a blue LED.
The Auna Rocketbox 2.0 is a well processed and stable companion who shines with excellent sound and practical battery. I currently use it when working in the basement, in the summer but arise many more applications (garden, beach etc.). I would recommend these speakers vollstens.
