Many things can be said about the iFuzen. If you're like me, browsing your iPhone whenever there's a spare minute, you should be familiar with the "oh shit my battery's almost out and I just had lunch". If that's all you think, you should probably look somewhere else. Because even though the iFuzen doesn't add too much bulk to your dearest friend, it does have an on board amp that both adds to the size, weight and price of this magnificent device.

The on board amp is actually the reason I bought it. The extra battery was just some kind of excuse for me to buy it without my fiancee calling me mad for buying more "headphone stuff". And what a glorious thing it is. The amp in the 4s isn't particularly good. The amp in the iFuzen however, is really good. So what does it actually do?

1. It makes the sound more "dynamic"
2. Widens and deepens the soundstage
3. Tightens up the bass
4. Adds some well deserved sparkle
5. Adds some warmth and what they like to call "a tube like sound" I don't want to try to explain how that sounds, I'm not a legit audiophile. Yet.

"Hey, I like cool stuff but I don't have very good headphones. I only have overly bassy IEMs..."
Don't worry. The iFuzen can help you. Somehow, the 3rd sound mode manages to make my cheap IEMs sound better. A lot better. It removes a good bit of the midbass hump and muddiness. It brings the recessed mids forward and warms them up a bit. Adds some sparkle. Voila! You have yourself a new set of phones. If you're leaning towards this device. Pull the trigger. Or well. Click. It's worth it. If you like music and you have an iPhone 4/4s, you should own one of these.

P.s. it drives bigger phones just as well. If you have better headphones, it will just improve those 5 things stated before. It will add some warmth and a bit of its' own signature but it's really a great device. Transforms your iPhone into a portable powerhouse.
