GOgroove SonaVERSE BX Portable Stereo Speaker System w/ Rechargeable Battery & 3.5mm Aux Port - Works With Apple, Samsung, HTC, Sony and More Smartphones, Tablets, MP3 Players, Computers & More

Pros: Small, snazzy looking. Feels sturdy. Decent feature set. It is capable of being rather loud without distortion.

Cons: Sound is pretty terrible and shallow. No bass to speak of. None. It's not full sounding, I don't know what these other reviewers were listening to. I'm not a bass head and even classical music sounds awful on this. Unit has power issues even when plugged in, randomly cuts out regardless of setup. Don't expect to be able to charge your phone and listen to music via 3.5mm jack.

Overall Review: Maybe a bad egg out of the batch, but probably not. The sound is simply awful. Which is really no excuse because the speakers are large enough to output decent sound. It's just a vastly overrated piece of hardware, it seems.

Pros: It's small. For something this size, it sounds great. It will take a USB flash drive, so their really is a purpose for all those old 512mb/1gb sticks. I limit it to that because you can't navigate the file system. You just can't get to the music halfway through the stick without some manipulation. So with USB sticks, you make a mix stick, plug it in and leave it. Same with SD/microSD. If you want control, you use your iphone/android with aux cord and have at it. I use it in this config most of the time from my Android phone running power amp. I've used it at the beach, while working (building out attic), while hanging out on the back deck. In a small room, it is surprisingly loud... loud enough to have to turn down to talk over. I haven't had any of the problems that other folks have (internal connectors breaking/etc), but I took head and treat it with kid gloves. I live the aux patch cord on all the time, and don't worry about unplugging/replugging. I paid 19.99 shipped.

Cons: Well, it looks and feels cheap. There is no real navigation of devices, and I I haven't found any hacks or writeups as to how this thing does navigation. It appears to be top level file only, directories sometimes read (magic, I guess), and uses alphabetical or other order. You need to have the aux device up and running before you switch the unit on, or it may not pick it up (it does some kind of device scan, but that too is magic).

Pros: These little things are GREAT! No frills, just PERFORMANCE. You get a LOT of good quality sound from a small box, with a LONG battery life.

Cons: None, from my point of view. Sure, it has no bluetooth or playlist display of any sort, but it isn't designed for that stuff. It is what it is, and it does what it does...VERY well.

Pros: Puts out decent sound better than the little accordian type single speaker unit I was using for portable sound.

Cons: Haven't used it a lot. But no complaints.

Overall Review: Got it on sale. Always a good thing.

Pros: For $20, it is a great deal and great speaker. It sounds very good for this size of speaker. It supports USB jump drive, Aux, and SD card. Love it.

Cons: no.

Pros: Playing good for a 20$ device. 3W rms Portability Easy to use Backed 3 years if you can reach them :)

Cons: Information are missing in booklet like what type of format type is needed on usb, bitrate supported etc

Overall Review: I bought this to use SD card (Picture on newegg had card slot) but my SONA is only USB. I'm Pretty disappointed to have a USB key sticking outside the box.

Pros: needed a spare for my luxa speaker that uses an internal sound oscillator to magnify the sound, just laid my phone on top of it. this speaker blows it out of the water, but you need to use a physical audio cable. full sound in a small square package. no annoying superbright retina burning leds. excellent price with promo code. I would pay up to $20 for this. You can keep the speaker near you without using headphones and get that "immediate sound", concert sound right next to you.

Cons: none, got it on sale with promo code for twelve dollars plus tax.

Overall Review: will buy another in the future

Pros: On sale it's a great price. The sound is very acceptable quality for a low-cost device. Rechargeable battery, does not require Bluetooth, nice size.

Cons: Not all that portable but much better sound quality than the really small BO devices (so I guess that's a con with a pro). The battery does not last terribly long (most of a workday usually).

Overall Review: I got a pair of these for less than the list price of one. Very happy with what I spent and what I got.
