“ 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
“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
There is an old saying that says everything is all about presentation, and these new RP-HJE 130 earbuds from Panasonic definitely follow that very well. As far as the earbuds themselves go, they are your standard pair of earbuds for listening to your favorite tunes and probably work very well. The real attraction here though is in the packaging. With these earbuds packaged up to look like a...
“ I bought this and the JVC HA-FX40 at around the same price($20 each). I like this for the better behaved highs, overall slight warmth, and what seems like a slightly better build quality. I like the HA-FX40 for its slightly better detail, although its highs are a bit too strong at times. The HJE355 has a very ergonomic shape and I think most people will find that it is very...” --JK1
“ 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

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.
“ The sound reminds me of the PX100. It is warm and detailed, with plenty of bass. It has more bass impact but less detail than the HJE355. The HJE355 also has better detail, better highs, and seems to isolate better. I bought the HJE450 before I bought the HJE355. Even though the HJE450 is good, I prefer the less expensive HJE355. ” --JK1
