Pros: excellent balanced sound. you will not get good bass if you do not get a proper fit in our ears. you must get a 100% seal or no bass. they have tons of bass, so if you don't hear - you DO NOT have a good seal. this is true of any in ear monitors - not just these. these are not ear buds that rest on your ears - these are in-ears and must be inserted in your ears to get a seal. if you are complaining about poor fit and "no bass" - guess what - this the reason!Start with the small tips and work your way up until you get a good fit and great bass. take your time - it's worth it absolutely necessary - with any IEM.

Cons: These have a thin cord. I worried they would not be durable, but so far so good. note I baby all my stuff so YMMV.

Overall Review: I'm tired or reading about no bass with various IEM I have that I know have excellent bass. if you don't understand what you are buying or don't take the time to read the instructions that come with your gear - you get what you deserve if you get poor results. Again FIT IS EVERYTHING! - so take some time and get a good fit. Also - practice putting them in so you get a good fit every time. One last time: If no bass - then you haven't put them in correctly. End of story

Pros: hmm - can't think of any

Cons: Didn't work - had to send back to newegg

Overall Review: My iPhone 4S would not play in both channels unless I held it an a very certain way with my hand - as soon as you let go - boom once one channel. then it stopped all together with the " this accessory is not supported" message. I have several other docks (none are Vizio) and never had this issue with any of them. Sent it back for a replacement - we'll see if the next one is any better.

Pros: It works... but barely 50% of the iphones built in capacity

Cons: However given its bulk, long charge time and initial cost I expected to get 100% plus equivalent capacity of the built-in iphone battery. Unfortunately it only recharges about 50% of the iphone's battery capacity so disappointing capacity in that regard. However it is very low capacity and takes many hours to fully recharge - go figure. I do like that it works with the case still on the iPhone. and will let you recharge your iphone with a mini-USB cable so if you don't have our iphone cable with you it lets you use a more common cable most people have laying around. Still it is clear to me why this thing only costs sixteen bucks now - that's about what its worth, but no more than that IMHO.
