Aquajam's AJ2 Comes in three colors, red, black, and yellow. The color schemes of each of them are all very nice and visually appealing.
It comes at a price of $139, but I've seen it around $99 in some stores like Kmart or Target.
The battery is a built in Lithium Rechargeable battery that lasts up to 10 hours. It took me about 6 hours to fully charge it. To charge it you twist off the loop on the top of the speaker and connect a micro usb cord to it.
It only weighs 1 lb and is very portable. You can carry it in your hand comfortably or in a backpack. I was even able to fit it in the pockets of my shorts.
It also includes a Bike Handlebar Mount, Carabiner, Handstrap, and a Micro Usb to Usb Cord, and 4x 3M Waterproof Tape Mounts that allow you to put it on a shower wall, a surfboard or even on the side of a boat.
It has a built in Microphone that allows you to answer calls by pressing the power button and use it as a speakerphone.
The speaker is designed to float so that when in water it will float with the speakers facing upwards. It is also IPX7 Certified and can be submerged up to 1 Meter (around 3 feet).
It also should be fully usable in snowy environments.
The speaker is 10 watts and has very impressive sound quality for a bluetooth speaker. The volume at max can also get really loud which is great for when your outside. It will be louder outside of water because when it is floating, the water will dampen the sound waves making it quieter.
The Verdict:
I've been using this every time I go swimming or fishing and am greatly enjoying it. The sound quality has greatly impressed me and all of the included mounts for whether your biking, surfing, hiking, or fishing makes it very appealing and great for everyone.
