really poor quality:
I purchased the speakers to replace the Macally ones I had lost. This looked like it might do the job for a lot cheaper. Oops! You get what you pay for (+shipping). Quality is a little thin but constant distortion and crackling make this just a throw away item. Don't bother.

Pretty simple...IT DOESN"T WORK.:
Got it yesterday. Didn't work. Just creates an annoying sound. Comes in the annoying package that just makes it a pain to return. Here is $7 I'll never see again. A shame they don't give you the option of zero stars. Amazon however is the best. Never had a problem with them, it's definitely about the product, not the seller.

Junk:
These speakers are not even worth the plastic wrapper that it comes in. I brought these speakers for my instinct sprint phone so that I can listen to music while I did school work, but the build in speakers on my phone sound louder.

Horrible!!:
Terrible quality! I would return them but it would cost more to ship them back than they cost to purchase....not worth the plastic they were shipped in. I would have given it 0 stars if that was available.

Great price, decent sound quality, low volume:
Pros: - Price: excellent - Compatibility: The compatibility for this item, unlike a lot of ipod accessories, is excellent because it will work with any portable music player device that has a headphone jack, which is pretty much all of them. So as long as the device can physically sit in the headphone jack, it should work for you and it does work for me Coby mp3 player as well as my brother's Sony mp3 player. It should work for all generations of ipods too, barring a physical impediment from it sitting properly in the headphone jack. - Sound quality: I used to have a Griffin speaker adapter like this for my old ipod and the sound quality from the Coby is much better. Cons: - Volume Control: There is no volume adjustment on the device itself, so you have to adjust the volume using the mp3 player. That isn't a problem in itself, but it doesn't get very loud, so don't expect to be playing this over a loud noise source like outside. - Battery power: This isn't really a pro or con, it just is. The speaker uses one AA battery and has its own on/off switch, so it isn't powered from the mp3 player. This is good in that the mp3 player battery lasts longer, but I often forget to turn off the speaker when I remove it from the mp3 player and end up draining the AA battery fast. It would also be simpler for me if the mp3 player and the speaker used the same battery type so I didn't have to carry extras of both battery types. There is no indicator light telling you whether the device is on or off. - Size: it isn't that large really, maybe the size of two thumbs, but I was a little surprised by that size as my old Griffin ipod speaker was the half the size. It isn't so large that you would have any problem carrying it around. Overall, I highly recommend this.
