I could not pass up sharing this simple smartphone ( Blackberry, iPhone, Droid etc) Speakerphone Enhancer. I wish I would have thought of this – This really is a quick and dirty (only if you leave the glass dirty) Solution that really works. I can’t believe how well this works. I tried it today and the sound is increased – Now this is not hi-fi – But it works in a pinch when you need a little extra boost. Make sure to put the speaker side down – The bottom of the iPhone down. This causes an echo chamber and increases the volume of the sound. Just a little quick and easy solution. Great from when you are away from your regular speakers or dock.
But if you want a little (Well a lot better speaker system for your iphone – I would suggest checking out this page at amazon: Iphone Speaker Docks.
