“First of all, I'd like to thank 'H20Fidelity' who recommended this IEM to me. I was not sure whether to go for this brand as i did not hear of it before. but thought of givin' them a try. Got it under 40USD. I had Sennheiser Precision 300-II before these and I liked them. The intention to purchase an IEM that was like Senn Precision 300-II was to have a pair of headphones that are just fun to...” --akshayshah12
“ 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
“I have 5 sets of the e30 with varying amount of time on them ranging from brand new to 500 hours and there is so much variation that I don't know which one to review here. But generally, I'd say the e30 is neutral/warm yet detailed with a pleasing full bodied sound. It's 'hi-fidelity' in the sense that it imparts virtually no sound signature/sound stamp of its own onto your music...” --thelostMIDrange

“Build Quality: Not much to say than a solid IEM. The outside is "gunmetal" it looks like metal and feels like metal, but then again. I have been fooled before. The clip ...is just a clip, no deficiencies or poor moving around from it. The L shaped 3.5mm jack is also good. No weird wiggling parts, feels and looks solid. As it's an earphone, this section is generally good. The tip of the earphone...” --bowei006
