Pros: relatively inexpensive. Feels well built.

Cons: The unit on very low volume sounds ok, although a bit heavy on the low end which muddies up the rest of the sound from the 2" drivers. Mine arrived with a blown left speaker, which clicks and pops on any input with the volume above half. It'd be a 3 star review otherwise. Shipping it back to to get a replacement will cost an additional $12. That stinks.

Pros: Great sounding speaker, even at full volume no cracking with bass. For the price it sounds amazing. It won't blow the windows out, but It's loud enough for me. Can be heard on full throughout the downstairs of my house. Housing is solid and seems to be a good build.

Cons: Not really a Con, but every time you adjust the volume up or down it makes a tone. I leave mine with the Volume all the way up anyway and use my phone for the volume controls. Not going to take an egg away for that.

Overall Review: I have bought other Rosewill products before, Never any issues, great Company.

Pros: Sounds great, amazing sound quality for size. Rubber finish and heavy weight makes it feel like a quality product. Good range. Comes with audio cable so you can plug directly in. Bat life is great.

Cons: Sound will at times tone down. Meaning it will sound like it slowed down but speed of music is unchanged. I think its the sounds pitch. This happens streaming or playing local files maybe once every 1-2 hours of usage. It doesn't seem to be noticeable to many people. Biggest con is the charger port. I've bought two of these. They get a fair amount of use but nothing i would call abuse. Plugging it to charge pushed the port out of the board and into the speaker itself thus ruining the product for ever once the battery runs out. There are no screws to open since speaker has a streamline design. So no way to open it up without ruining the speaker. I got about a few months out of both speakers before this happened and when it did i felt pretty sad about it. It's not a cheap speaker and the quality of the product i thought was a fair tradeoff till it broke. Two times, the same way.

Overall Review: Disappointing. i feel like this is a design flaw on a well made product. If this charging port was more secure i feel like the speaker would have potentially lasted me years. It makes me weary to buy Rosewill products, and all portable bluetooth speakers in the future.

Pros: Excellent sound (I listen to mostly death metal) No loss in bass or kick-pedals Wireless Bluetooth Has a very solid build, no cheap feeling to it Can get really loud without any distortion Price is worth it for this beast.

Cons: I can't hold the volume buttons to change the settings, I have to click them. No biggie though.

Overall Review: Needs to include an aux out slot so I can hook up multiple Ampbox speakers if I wanted too.

Pros: Decent Sound / charge lasts a while

Cons: Charge port broke after 1.5 years of use - Not easily to service. The 4 screws under the footpads do not get you into the device.

Overall Review: Called Rosewill - they just wanted me to buy a new one! I will not be buying another on for more than $10

Pros: Decent Sound for it's size Decent Battery Life Easy Pairing Super Portable Appealing Design

Cons: By the tenth time I used this device the usb charging port broke away from its board. That's it; it's dead now.

Pros: So far it has performed as expected work just fine no real issues and can be used as speaker phone it's nice if you're working on the car uses a standard Cell Phone USB cable to recharge.

Cons: Time will tell.

Pros: It sounded good for the size and the battery life was somewhat impressive.

Cons: The charge port broke off inside the device. It literally came off the circuit board.
