“Full review here: http://www.head-fi.org/t/699630/review-dunu-dn-1000-3-way-hybrid Sound: This is the main part of the review, and the most important for every audio gear. Dunu's house sound usually leans towards to either the warm and smooth, or bassy signatures. Even their single balanced armature based IEMs were more mid-centered with rolled-off highs and lows....” --Zelda
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

“ First off, I'd like to thank the folks at DUNU-TopSound for providing me with samples to review Up for review today are a pair of balanced armature based IEMs. Priced solidly within the bracket I would consider “mid-range”, these have a great deal of competition right out of the gate and one has to wonder whether or not DUNU’s newcomers can stand up to that competition....” --TheGame21x

DUNU is a fairly new company and was started as a brand of the Top Sound OEM making IEMs that utilize very high quality housings that have a similar look and feel, but better build quality to the Monster IEMs. I have had a chance to hear some DUNU products briefly, but as I now stick to custom IEMs and higher priced universals I didn’t perform a full evaluation. I was a little surprised...
“ 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
“ Review of DUNU DN-17 Crater A Little Information I would like to thank DUNU for being extremely generous and sending me yet more gear for review! It was a bit of a surprise to receive these headphones, as I was not aware of entering any contest or anything of that sort and was not expecting them. However I do of course welcome new gear for testing, so it was a lovely surprise to see...” --Gatepc
