“   I am always on the search for great in-ear headphones, however I always seem to find the same problem, because they are in ear, they tend to have very small drivers, meaning there is never much bass, and in most cases the highs are also messed up in an effort to get more bass! So I am always on the lookout for in-ear headphones that have good bass, yet have a nice flat frequency...” --MyConnor5Review

“These headphones have powerful bass (comes with a lot of ommph) which is good and lets honest if your interested in these earphones main reason will be for the bass    For listening to music such as Pop and dubstep these are very good as the beat/bass just comes alive. For rock I found them good but not excellent. For classical and new age music its OK I found them a...” --butter30

YUIN PK3 Earbuds

YUIN PK3 Earbuds

“ 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

“ 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

“Introducing HiSound Audio's Crystal IEMs   After reviewing HSA's E212 and PAA-1Pro recently, Jack approached me and asked if I'd like a review sample of the Crystal (IEM) and Living (Earbuds).  I jumped at the chance, and after paying for the freight - they duly arrived a couple of weeks ago.  I’ve listed price at the RRP of  ~ USD $69 – this is not what I paid for them...” --Brooko

“Hisoundaudio Golden Crystal       First I’d like to thank Jack at Hisoundaudio for giving me the opportunity to purchase the Golden Crystals, or GC as I’ll reference them, as they are not yet available from any US dealer.   Meet the super tiny Golden Crystals.  They are the smallest dynamic driver on the planet (I think the Monster Tributes are 5mm as well, if...” --shotgunshane

“ 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

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.
