“TL;DR : Don't be lazy, I already made the review super short Let's just keep this short, I got the MMX102IE (same version just with a mic and 1 button remote) for about 40$ cuz of a discount (You could still get it at about 70$ in my country) I will be judging from 4 aspects : Design, Build Quality, Comfort, and Sound Quality Design (4 out of 5) Decent design, doesn't scream...” --Zero Decibels
“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
“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. First I tried them without the foam covers and they sounded awful. I originally thought I had been sold a pair of fakes but after using them with the full cover foams I am impressed. they have good definition and separation in the mid and high frequencies. The bass is...” --thebluebulk
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.
Technical Details * Impedance:32 ohm(at 1KHz) * Frequency response: 20-20,000Hz * Sensitivity:120 dB (at 1KHz) * Max Input Power: 400 mv

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
“ Beyerdynamic's dtx100 is their top of the line dynamic driver iem. It has a bass driven sound very similar to the 60/80 which is a signature I like. Bass heads may be left wanting as will detail freaks but they are fun with a punchy attack and very user friendly. They exhibit marginally less bass than the 80's but extension is, if anything, better, as is clarity. Because of this bass...” --Marcus_C
“ In short: + Stylish looks + Comfortable + Powerful bass reproduction, flat but present mids, rolled off yet detailed and even sparkly highs, usually good separation + EQ-able +- "Dark" sound signature, tends to favor the bass and lower mids. Not perfectly analytical nor overly musical +- Best for pop and pop/rock - Lack of sub-bass detail, bass can be boomy - Impact not consistently...” --Shonen84
