“ 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

“ On my quest for the perfect sounding IEM for mobile use I came across these headphones that are rather underrepresented in the forum. The Panasonic RP-HDE10 are technically quite interesting as their 11,5mm MLF (multi-layered film) dynamic driver is actuated from both sides by a "HD Axial Dual Driver Unit" — a double set of coils and magnets.

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 HJE355 also has better detail, better highs, and seems to isolate better. I bought the HJE450 before I bought the HJE355. Even though the HJE450 is good, I prefer the less expensive HJE355. ” --JK1
“ Overall I have been satisfied with these phones. I would not recommend paying full price for them like I did. ” --Skoch
“ 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
