Lumsing MM526 Unboxing

Contrary to most of the items I’ve received from Lumsing, this box was complete with graphics on the exterior, depicting the look of the MM526. It also contained information about the technical specifications and features of the device. The box was clearly meant to be on a retail shelf.

Pulling the foam packing out, revealed the waterproof bluetooth speaker and the two attachments that came with it. There is also a users manual, and a power user card. The attachments are a USB charging cord, and an AUX style male to male extension cable, to allow a direct connection to the speaker. The latter is helpful if you are still holding on to that old iPod; this will fit right into the headphone jack in the iPod.

I didn’t find anything immediately wrong with the construction of this device. It is quite solidly built, and did spend a few days bouncing around my work van, with no ill-effects. The carabiner would turn out to be very useful, as I tend to forget things, so clipping this right to my belt is a nice and easy reminder it’s still with me.

MM526 Features And Specs

Here is the list of technical specifications on the MM526:

The MM526 includes a stereo amplifier and dual voice coil speakers. It also provides what it calls “Intelligent Voice Prompt” which tells you exactly what is going on with the device. If it is in Bluetooth mode, instead of AUX (something plugged into the headphone port), it will announce “Bluetooth” when you power it on. Once you have connected a device to it via Bluetooth, it will also announce that.

In addition, wireless speaker the MM526 meets or exceeds IP64 standards for dust, moisture and fall damage. The solid construction I was speaking of really points to this fact.
