Pros: Real tuneable sound via the three different bass ports.
inline Mic with button for phones
Great detail and clarity from a dynamic driver.

Lots of great accessories, plenty of eartips so everyone can find a goo

Cons: I couldn't find any fault with these.

Summary: This is an amazing dynamic IEM for this price, especially for those that are upgrading for the first time or have a wide range of musical tastes. I listen to a lot of classical music, acoustic, jazz, some progressive rock, and Electronic dance music. Being able to switch out the ports on the back of this IEM has been a great feature to have when I go from listening to classical at home on the weekends to some electronica for my runs. By no means is the neutral bass port, bass light. The bass is still very punch and present, however the gun metal ports bring the bass more forward and add some midbass emphasis. I like the gun metal ports for listening on runs or walks, and the silver for more critical listening at home. The black ports are strictly "fun" for Drum and Bass music with a heavy emphasis on the bass. The mic is especially handy when I am walking the dog and streaming Pandora from my phone. The mics sound is clear for the caller and I don't need to hold it up to my face as the positioning is quite good near your face rather then down lower like some sets. I used both the double flange tips and the large single flange, micro-phonics are non existent when worn over the ear with the added benefit of bringing the mic a little closer while outside. Worn down there are some micro-phonics as cane be expected from any IEM. Using the included shirt clip takes care of this issue. The construction quality is excellent from the plug through the microphone to the strain reliefs on the earphones themselves. I especially like the smooth, clear/silver cable that was also on the Mee M9 that I own. In summary, these are a great sounding pair of in-ear phones with the option to customize the sound for those that are unsure about what they like. They are a wonderful value and I highly recommend them.
