“ These shiny, luxurious little in-ear monitors that come in a very exclusive box sure feel very expensive in terms of look and feel. They shells attach behind your earlobes and rest comfortably there. This is the most comfortable in-ear headphone I've worn. They can be driven from an iPhone as well as an amp, sound will not be any different. The sound of these...” --Lan647
“these are ok, i just bought them. They have the same dynamic musical presence as their on-ear, the Q-460. Construction is all plastic, but the cable seems flimsy. same as the Q-460s. I guess these are the compromises concerning the lower lines of the q-series. ” --hanglee65
“ 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
“ i cannot give you a price comparison or compare it to others in its price range as i was given these as a gift. but i loved these things. the bass was impressive, good highs, and smooth mids. although they tend to be a little unclear sometimes i find them to sound very enjoyable and stunning. they didn't distort or clip at all and i noticed no sibilance at all. the only thing i can complain...” --bcasey25raptor
“After starting to review a few IEM's in the past week I decided to slip these babies back into my ears as a reference point for the other IEM's. After doing so for a few minutes I realized these really needed a proper review as they definitely keep up with a lot of gear that is more expensive. As can be seen by the picture these are very tiny being the smallest IEM I have owned to...” --dweaver
“ 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
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
