I've had this for about a month now and I use it every day and I have to say WOW this is something great. They took a little getting used to, but my goodness, they really are awesome. To be honest I much prefer it to my HD660. In any case . Here's the breakdown: - Bass is certainly not a light bass, but it's not a heavy super bass either. The bass is deep and supports the music very well. When the song calls for it, there's bass, and very nice bass. - Mids are the strength of this IEM. The middle area is so clean and smooth. The voices can sometimes sound quite intimate and lively. They just draw on other frequencies and create this beautiful symphony that is this IEM. - Heights are one of the areas I have a bit of a problem with. Still amazing. Coming from something like the HD650 or HD660 you'll find the highs a bit airy and quite revealing. The only problem I've had is a dip around 10,000 which sometimes makes the sound seem a little "wrong" to me. Other than that, I can't find any issues with the FR of this IEM. It's damn good - the picture/sound stage - in short, the picture in this IEM is just awful. It's nothing special, but it's certainly good enough. However, the soundstage is rather unexpected. This is pretty amazing for IEM. I would honestly say that it feels like listening to headphones and using my whole ear to hear and not just the ear canal. - Conclusion - I was a bit skeptical at first, but after a month of use, I have no hesitation in saying that these are lifeguards. I run them on the FIIO BTR5 and being able to listen to silky high-resolution music anytime, anywhere is a true luxury that every music lover needs. If you want an IEM that's surprisingly good at almost everything, get this one.
