“Only short review from me. Since the "The Wirecutter" claimed these would be the best IEMs under $100 I had to try them when I saw them for $49 on a very special sale. They are fantastic allrounders, the bass is pronounced a tad bloated maybe, but pleasurable to listen to, clarity, pretty decent miss and good details in the highs make this headphone a steal for the money. ...” --Koolpep
“Before I begin with my review of the Beyerdynamic XP1, all of the below are solely what I’ve managed to get out of the IEM, I suggest to try it out or read some other people’s review to get a clearer picture of the IEM, as my opinions are not absolute and other ears might have listened differently. Sound: First of all, this IEM is one of the three IEM that Beyerdynamic released...” --SawItComing
“ 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
Efficient, powerful neodymium drivers deliver fantastic sound with low distortion and great resolution, even when used with low output devices such as smartphones, tablets and laptop computers.Perfect fit and isolationWearing comfort, isolation of ambient noise and a deep bass-response are crucial for any in-ear headphones.

Starting off simply, let’s discuss the accessories that are included in the packaging. For starters, the DX 160 iE comes with a small carrying case that...” --AxelCloris
“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 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.
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
