In the box
Logitech UE ships the Mobile Boombox in a transparent plastic box that consists of two parts. In the bottom there's a cardboard partition with the quickstart guide in several languages, a micro-USB cable and cleverly designed power adapter with plugs for the UK and continental Europe. The speaker itself is on display in the top, transparent part.
The Mobile Boombox itself is covered in a type of coarse rubber, that gives the impression it can handle a bump or two. The front consists of a large speaker grill, on the top three buttons that have been seamlessly integrated into the rubber casing, and the back has the on/off switch, a micro-USB port and a 3.5 mm jack.
When you turn on the speaker, you can connect it right away via Bluetooth. If you want to connect a second source to it, you have to press and hold the Bluetooth button at the top until the blue light starts flashing again. The Mobile Boombox can have two devices connected to it at a time, which you can switch between without one of them losing the link. The speaker can also remember a total of eight Bluetooth devices, so you don't have to pair them each time. This is a fairly standard feature on Bluetooth speakers.
The connection uses the A2DP profile, but it's unclear which codecs that are supported. SBC obviously, but if mp3 and aac also word is unclear. No mention is made of Apt-X, our favourite Bluetooth codec. Only Logitech UE's flagschip headphones, the 9000, supports Apt-X. The Mobile Boombox is also compatible with AVRCP and HFP, for remote control and for serving as mobile headset. You can make calls with the Boombox, because it has an integrated microphone.
