HMDX Jam Box Bluetooth Speaker

by Josh Osborne Osborne.Josh@MacPhail.org

I've been using the HMDX Jam Box for my daily speaker needs  for the past month now. I teach in community partnerships, Music For Life, and individual music therapy sessions, so I have often been confronted with the need for a portable solution to amplification.

I have to say, I'm incredibly impressed with the volume output of this little device. It fits in the palm over your hand, weighs a little over a pound, and can project convincingly in a large space. I recently took this speaker on a road trip with me; even with the all the windows down, I could still hear my music over all the noise.

Additionally, this device is Bluetooth capable, so it is cable-free.  There is an 1/8in input option if you don't want to use Bluetooth. This may be a viable option as enabling Bluetooth on our iPads or phones diminishes battery life. Personally, I prefer using any option that is cable free.

The con to this speaker is that the battery life is about three hours. I need to charge it in the middle of my work day in order to maintain a charge to get me through my teaching schedule. This device is charged via mini USB port. This is the same means of charging a standard cell phone or Android smartphone. It does not come with a charger, but you can use any phone charger connected with a mini USB cord. I actually carry a portable charging device with me at all times, so this is how I keep the speaker charged during the work day. I have this demonstrated in the picture below.

congratulations guys, quality information you have given!!!


Hanno, you could definitely keep it plugged into wall all the time. That is essentially what Im doing with the portable charger. im just on the go so much, sometimes there isnt a readily available wall socket. I would use a smartphone charger, it's a small device so it wouldn't need something as hi voltage an iPad adapter.


I bet you could plug the usb into a converter like the ipad a/c converter. Check the voltage first though. I know my kindle can charge using my ipad adapter. I've also charged my kindle off of the ipad using the usb/camera adapter kit.


This sounds great! Limited battery life seems like the main weakness. Can the speaker be plugged directly into a wall socket, instead of running it on battery power?
