Testing:
The Super.fi 5 Pro's were run through their paces for about a weeks time. During that period, I used them as my primary sound source about 95% of the time, the only time I didn't use them was when I was working on mixing projects for which my monitors were the mandatory system to use.

I must say, I thought the Super.fi 3's were amazing at the time, especially compared to many other competitors in the same price bracket, but the Super.fi 5 Pro's simply blew me away. When I first put them in I didn't really know what to expect in terms of sound quality since these are the first set of dual-driver earphones the site has reviewed. Let me say, I had to double check to make sure I was actually listening to the song through these instead of my monitors when I first put them in. The tonal spectrum and quality is amazing. Imagine listening to your songs on an expensive set of hi-fi speakers, now imagine being able to stick those speakers in your ears and take them everywhere with you. The Super.fi 5 Pros have an amazing sound quality and depth to them when compared to any other earphone I have personally used - and I have used a lot.

Conclusion:
If you demand only the best when it comes to your audio listening, then look no further than the Ultimate Ears Super.fi 5 Pro set of in-ear earphones. If you're reading to take "consumer grade" to the next level, then these are an investment you will never regret.
