Grace Digital GDI-AQSCE104 Eco Extreme Waterproof Floating Case with Built-In Speaker for iPod, iPhone, Droid, and MP3 Players (Yellow)

Quick overview. Good speaker Just what i was expecting maybe bettter.

Design- Nice hefty design. I got the orange one very pleased with choice. Not bright orange but a nice dark orange. This way i can see it in the grass but it also look cool. The only thing i would change, i knew this going in, I would be to put a bigger D-clip on it with some 550 cord. The plastic loop that the current clip uses is kinda small.

Durability- It feels durable and will take some abuse. I have not tested it's waterpoofness but it has a rubber seal and the latches seem strong. They also has a button lock on them which is nice. I would take care on rocks though because it is plastic on the face and back. Plastic is brittle so it may survive a drop on the ground but not on the rocks.

Sound- As expected it's not earbleeding loud but loud enough. It should be fine for a group of people huddling around a table eating or playing cards. I compared it to my other portable speaker its about the same but with more bass. I got this for its waterproofness, size and durability not for the sound. I like that it only needs 3 AA batteries.

If you want a larger speaker that is also water resistant and durable try Sangean U-1 or U-3. They seem like larger and louder sound systems that are tough. But their line ins are on the outside. If you want a fully enclosed unit try the fatbox. but all three are large. I choose Sangean because unlike other rugged sound systems they run off regular batteries not ones for power tools.

Update- For some reason it sounds louder now. it could be the songs. But now i would recommend it for a large group. For personal listening i hardly go over 1/3 turn Also I have noticed that even at max volume i don't hear any distortion, which i did on other portable speakers.

***end of summer review***
Took it to the beach and camping many times. Words can't describe how perfect this speaker is. I think it's a great compromise between sound (it is still plenty loud, I don't see a great need for anything louder) and size. I just throw it in my pack or clip on and off i go. Also the fact that it use AA batteries is great. When the power goes out you swap out batteries and keep listening and rocking while others need to recharge their internal batteries. Also for the people who don't like wasting batteries you can always buy AA rechargeables.

I wasn't expecting much sound from one little speaker, but I'm impressed. It's no Bose of course, but it will be perfect out on my kayak! I'll take great comfort knowing my Zune is so well protected.
After using it several times out on the water, I still give it 5 stars. When the batteries get low, it sounds like the speaker has blown. Put fresh batteries in and sounding good again. I use rechargable to save money and better performance. I can't tell you how many have stopped me on the river asking how I have tunes on my kayak!

I was quite surprised... I wanted to occasionally listen to CDs outside or in the shower without having to worry about water damage. Couldn't find a CD player that I liked, so I bought this and stuck an old iPod Shuffle in it. Very excellent sound for what it is; I've bought mini 'speakers' before and they are nothing like this. This little box produces a solid sound that allows you to actually enjoy your music.

The design is sturdy, and there is even an air-pressure differential filter that protects the speaker in case you take it on a plane or up a mountain. Plenty of room inside, the device was much bigger than I thought it would be.

I couldn't find anything like this elsewhere; if you need some rugged and waterproof portable-audio, then this is surprisingly well worth the money.
