Portable Silicone Horn Stand Acoustic Amplifier for iPhone 4 - Black

Pros: This is a very cool item! It really makes the phone sound much MUCH louder. With this on, four volume bars is as loud as max (16) bars without it.
It's super simple to use. You just have to connect the two pieces together and slip your Iphone 4 into the slot.
It uses no batteries or external power supplies. It's just a simple horn using basic acoustic principles to make the speakers louder.
Stands up in portrait or landscape mode.
Soft silicone material seems pretty durable. You could accidentally sit on it and it would just spring back into shape.

Cons: No bass, just mids and highs. That's to be expected since it's a small horn, and the Iphone speaker isn't that great either, so it doesn't have much bass to work with.
You most likely have to remove your phone case in order for this to fit, unless you happen to have a really thin bumper - like paper thin.

Other: Awesome product.

Pros: ok, when i ordered this product i aws expecting it to be a miniature speaker that plugged into the haedphone jack of my iphone but it acually just uses the horn to amplify the noise from the iphone's speaker ( Which i would personaly prefer because it doesnt use up my battery ). It really does amplify the volume by an extremely noticable amount. Another added bonus that i discovered is that it also works with my ipod touch aswell.

Cons: none that i can think of, it is agreat product.

Other: I love my amplifier and would purchase it again without hesitation.

Pros: ~ does not use iphone's/ipod's battery
~ amplifies the sound using a horn
~ amplifies the sound alot louder than the iphone/ipod can produce
~ fully made of silicone so can be put on iphone/ipod easily
~ can still charge iphone/ipod with this attached
~ doubles as a stand for iphone/ipod

Cons: ~ none that i can find

Other: if you are looking for a cheap way to listen to your iphone's/ipod's music and do not want to spend alot of money on speakers then this is your best bet

Pros: - very useful item - does increase the volume in a couple of times - does not use battery power, and it is useful because it can not charge the battery when the iPhone in the horn - can be used in the office and at home because it has a small size and can be placed next to or behind the monitor - sustainability is on the table

Cons: To use the horn every time it is necessary to pull the iPhone out of the case that is not very useful if the iPhone fits tightly in the case

Other: - I like to use it - Not regret buying

Pros: This is a great deal for the iPhone. It comes in a very low price, it is friendly when it comes to the environment. No need for power or batteries. It fits your iPhone and it increases the speakers in a very surprising way.

Cons: So far, I have not found any cons. It does not take power, it is cheap, and looks good.

Other: I would highly recommend it. Very cheap, it delivers a good sound from your speakers. Good deal!

Pros: It works, without batteries, wires or anything else. It's as simple as creative; you will notice how the sound of your iphone seems to be magnified. You can even look movies with it fitted in your iphone. It works in horizontal and vertical position (you can watch movies using it).

Cons: Mine came with a scratch in a corner, but it stills work. The only problem is that I can only put my iphone in horizontal position and not in vertical. Mine came with a scratch in a corner, but it stills work.

Other: It amplifies the sound in a natural way, without using anything but its shape.

Pros: This is a cool gadget. I saw it on a coupon on line selling for $19.99. So I looked at DX to see if they had it and good thing too. For $3.30 how can you go wrong. The sound isn't the greatest, but it amplifies it enough to hear it clearly. If your expecting symphonic sound, I suggest you consider spending considerably more. But for outings it's great and you don't have to worry about it getting wet or dirty.

Cons: Nothing really. It is what it is.

Other: I bought a bluetooth portable speaker that produces great sound. But this no-nonsense gadget does the trick. It was so good in fact that my family thought it was cool. So I bought 3 more. One more for each of them.

Pros: This product amplifies the sound perfectly, no need to carry cables to connect, you can save anywhere, if it gets dirty you can wash it with soap and water.

Cons: I can't use it upright without support him because it falls. In horizonal position no problem.

Other: In conclusion, it is a cheap product, portable, does not require batteries or cables, convenient, easy to use.
