“Late last year, Brainwavz released a number of great IEM’s in the R3, Delta, and S1. The S1 seems to be Brainwavz’s attempt at making a sporty IEM, and pits it to compete against the very competitive $60 bracket. As with the Delta, I reviewed these last year, but since I can’t find it, I’m guessing I never uploaded it before my computer crashed, so this is another short rewritten review. The...” --Ishcabible
“I don't normally write reviews so I'll be all over the place but here we go: I listen to mostly electronic music. No specific genre in it, but it ranges from Ambient to very hard stuff (think The Bloody Beetroots). These are able to keep up with my ears. I'm not highly picky with my audio but these please me greatly for their portable usage. My home pair of...” --Mgear
“I bought this in 2012-06, when my Brainwavz M2 broke. It was given a Sonic Diamond by ClieOS for the pre-order price and 4.2 / 5 for the sound quality, so I expected quite a bit. Unfortunately, the cables are nowhere near as good as those used on the M2. The build quality of the speakers seems quite okay, though. Compared to the M2, the bass is considerably weaker, but the...” --Kadano
“Very nicely balanced overall. Bass very slightly lacking, but this is a matter of taste. Lots of tips to choose from, and came with foamies! Cheaply put together though. Loads of microphonics. Clip is useless. Thought I heard some imbalance but it went away with burn-in. Questionable quality? After further burn-in, my Betas became very bass...” --inline79
“ 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 PK3 is a great, warm earbud. It does vocals especially well because it is very mid-focused. It has impressive bass extension, not especially strong impact; the trebles are smooth and may roll off too soon for clarity and detail nuts. But the mids are what the PK3 are all about. ” --kmhaynes
“ 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
