Portable Silicone Horn Stand Acoustic Amplifier for iPhone 4 - White

Pros: Works 100%, it makes the sound louder not very much, but this could be a alternative to a iPhone dock if you use it at home, but for outside use with car and wind noise it wont work as well

Cons: To soft it is made from the same material as the cheap silicone covers, the good thing about that is that you can throw it into a wall if you want to and it wont break
The softness also does that the iPhone don't fit tight, as I thought it would be like

Other: If you want you iphone to play music louder or just want your alarm clock to be loud, then it's perfect and the price is not to bad looking at what you get

Pros: Soft, it wont hurt your iPhone.
If you have a super slim case, it'll fit in without undressing the phone because of the maleability of the silicon "amplifier".
It works either vertical or horizontal position.
It doesnt need bateries.
Unbreakeable.
Nice touch. If u dont touch it looks like mat porcelain.
The sound gets louder.
Interesting visual aspect.
Waterproof.

Cons: It raises only the medium frequency sounds.
Does not work well outdoors.

Other: I loved it!

Pros: Noticeable volume increase. Virtually unbreakable silicone. Fit is good.

Cons: Would have liked a tighter fit with some inner reinforcement to better secure the iPhone. Makes the sound slightly "tinny".

Other: For $3.30 you are not going to get a better device to get audio from you iPhone. Headphones would sound better, but are not always what you want.

Pros: made of good silicone fits iphone and i could put my ipod touch 4g with a cover in too. increases the volume a tad bit waterproof

Cons: there was a black splot that cant be removed(Insignificant) one of the sound hole is useless and does not amplify sound through the horn but the other does.(it's blocked by the silicone) but it looks like it was done on purpose. probably because of the price, i think the pricier one has sound amplification through both holes.

Other: great as from what i seen in shops around town, these cost half the price, and probably has the exact same quality. GREAT!

Pros: If you have trouble hearing your phone ringing all the way from the other room, this amplifies the iPhone's ringing sound

Cons: The only con I can think of is that it's pretty useless. No one leaves their iPhone somewhere around the house ...

Other: Too bad that this horn isn't suitable for other phones, plus it's a bit pricey for it's sole purpose of a table mount. But it is nice as a present or as a gag - since you can turn the volume all the way up and scare your friends or co-workers.

Pros: Cheap, Good, Easy to handle, Very useful, No need electicity to make sound higher

Cons: No cons! Very good product. But there's only one hole that's leading to the sound, I don't understand why it isn't 2.

Other: Conclusion: Very good product, the sound is higher, a lot higher, I really recommend it to anyone who has an iPhone, i think it even fits to iPhone 3g and iPhone 3gs!

Pros: I'm really amazed with this product. Seems that does miracles with a small piece of plastic. It emits a sound considerably louder than the Iphone can produce alone. The material is very good and sturdy, holds the phone very well. Not as loud as a speaker power, but produces an amazing sound!

Cons: Not as loud as a speaker power, but the price is very low, so it is worthwhile. Can not be used with the case, as it sits tight on the phone, but I can not consider this a counter

Other: Totally recommend, you will be pleasantly surprised with this product

Pros: Simple basic solution for making your iPhone louder. Build quality is reasonable for the price.

Cons: Sometimes the bottom bit becomes disconnected and I have to push it back in. Sound quality isn't the best, but that's to be expected given the item's design. MUST be used on a very flat surface (e.g. table) or it'll fall over.

Other: Great functionality, draws no power, great price, very portable.

Pros: this is the perfect way to listen to your iphone in the shower. it amplifies the sound to a reasonable level so i can hear it over the running water but it's not so loud that i can't hear anything else. the iphone is upright so i can easily access its controls while in the amplifier. makes my showers and kitchen work so much more fun. the featured button works perfectly (and it's actually easier to use that button than the iphone button) and there's very easy access to the volume controls. it doesn't slip, even when the surface is a little wet. the silicone is very good. there was no smell to it. the packaging was very good and assembling it was VERY easy. i didn't even need instructions. it is also very small and light so it's easy to take it with you anywhere you go, or even use it in a car. it is very easy to use. i taught my mother to work it in less than a minute.

Cons: i have to take it out of its protective case in order to use it. it is only suitable for iphones so no one else can use it in my family. needs a straight surface to stand on. i wish i could somehow hang it from the ceiling. it's not loud enough to be used outside.

Other: BUY IT! i use it every day at least once. it was the first thing i unpacked when i moved. buy it for yourselves, as a gift or to hand out at a party. it's very cheap and so useful. i'm going to buy another one so i can keep one in the kitchen and one in the shower.
