“I use these IEM's at work and during travel, it's very easy to transport with the small metal case. It was difficult to achieve the good isolation, i tried 10+ pair of silicon cushions and i finally got one which fits perfectly into my ears. These are very sensitive IEM's, if you hate source noises stay away from them, i hear little hiss even with my desktop amp/dac combo Corda Aria, probably...” --Lewzke
“ These were my sweetest sounding head-gear yet. It would be brilliant all-rounder if it would not require a portable amp for portable use. This is the first reason i left it, otherwise i almost got an ear infection from those foams.., they get dirty in a few weeks of massive use. I recommend them to clean, i boiled them in water. ” --angevoi
“ Ultimate ears metro.fi range are often overlooked on these forums. There is a simple reason for this, they are not worth the price they quite often retail at. They are, however, frequently on special offers and very good deals, i've even seen them being given away with other things costing only about £50. Obviously when earphones are on special offer they should be compared to others in their...” --Marcus_C

“Looking at the picture of the PK3's I wasn't expecting much. They look and feel cheap using a generic case for the drivers making them easy to fake. (In fact my first pair were fake!) these earbuds sound GREAT! Especially considering the price ($44) I have a few pair of earbuds in this same and higher price range and these PK3's knock all of them out of the water. They have a flat sounding...” --thebluebulk
“ These were my first IEMs, so obviously at first I thought that these were the pot of gold at the end of the rainbow. But after awhile... Bass is clear and punchy. Highs are pretty clear but high mids can get a bit muddy IMO. I'll be honest, it takes a lot of work to get these to fit, and once you do, they are really uncomfortable, at least for me. ” --vleung92
“ Ok first of all I will be using my Sansa Clip as my source as I feel an iem should always be tested with portable sources. I paid $200AUD for them brand new, which is dirt-cheap by Australian standards. I do not believe in burn in, especially for armature drivers - owning and listening to many iems has shown me burn-in is just a mental phenomenon where the brain adjusts to a new sound...” --ProjectDenz
PK2 earphones are the low impedance version of PK1. Although not as good as PK1, PK2's sound signature is similar to PK1. You don't have to drive PK2 with an expensive head-amp. If you are looking for something with high performance/price ratio, PK2 might be the best choice.
“ Well firstly this is not a true iem. The sound is about as great as one could get from an earbud. In my limited experience and without trying the pk1, I would say these are the finest buds you can buy. With that said, these are not for everyone, this is a niche product within an already niche market. I find driving it with my D12 anaconda makes for a pleasurable sound,...” --Jamesdeandoa
