| 9 mm Driver | Neodymium Magnet |
? The Panasonic RP-HJE120 Ergofit are the most famous earphones on Amazon with an almost perfect 5 stars rating and over 40,000 feedback scores; adding the fact that they are pretty cheap we thought they deserved a space in our database of earphones reviews. With a slightly larger than average dynamic driver (9 mm), a neodymium magnet and a declared maximum power capacity of 200mW, Panasonic may have manufactured an interesting earphone, but let’s don’t rush and see the results at the end of the tests.
… the most famous earphones on Amazon with an almost perfect 5 stars rating and over 40,000 feedback scores.
The housings of the Panasonic RP-HJE120 Ergofit are made of plastic which result in a very lightweight pair of earphones. Part of the lightweight has to be attributed to the thin cable, but besides the fact that they do not add much weight to the total package, using such a thin cable sacrifices durability and the quality of the rubber used on the cable does not provide them a good tangle-free performance. Do not think that this cable issues only happens with cheap earphones, the premium Sony MDR-EX7500/800ST are notorious for having a pretty bad cable (that resembles in many ways the one from the Panasonic RP-HJE120 Ergofit) and they were the 2nd top of the line earphone that you could buy from Sony some years ago.
The Panasonic RP-HJE120 Ergofit can be purchased in a very diverse combination of fun colors: green, red, violet, pink, orange, blue (like the unit we are reviewing) or the usual classic white or black.

Bass & Sub Bass
The Panasonic RP-HJE120 Ergofit have some mid-bass punch but not much sub-bass, they mostly lack bass depth. For none bass-intensive music they might suffice or could be a good option for people that prefer more conservative bass that does not take over the whole sound signature. On the other hand, if you are planning to listen EDM or even pop music that you enjoy to have strong bass you could feel disappointed. With an EQ the RP-HJE120 Ergofit distinctly increase their mid-bass punch but sub-bass still does not shine.
… could be a good option for people that prefer more conservative bass…
The Panasonic went through our extreme bass test handling 40% of a Fiio’s E12 maximum power when setting the amplifier to high gain and turning bass boost on (also a custom basshead EQ was applied). The results were a remarkable increment of mid-bass punch strength and sub-bass depth but not that intense as to enter basshead territory, they do not offer any type of basshead rumble or impact. As to be more specific, they are more inline with what a good microdriver is capable of producing (for example: the UiiSii Hi-705 and even less than the Remax RM-565i), far less than its bigger brothers the Panasonic ErgoFit RP-TCM125 and the Panasonic ErgoFit Plus RP-HJE190 or other highly popular earphones as the JVC Gumy Plus HA-FX5, the Inpher FUQING B-2 or the KZ ATE. To be honest, we were expecting a bass response full of impact, punch and depth coming from them considering it holds a neodymium magnet, a slight larger than average dynamic driver and the maximum power capacity of 200mW reported by Panasonic.

Mids & Vocals
Mids are laid back and lack energy. The recession is more pronounced on lower and middle mids but higher mids are neither exempt of recession. The higher mids recession grants the Panasonic RP-HJE120 Ergofit mids that are never harsh and pretty non fatiguing. An EQ slightly help to improve mids and vocals performance but they start to sound a bit boxy.
Highs & Treble
Highs on Panasonic RP-HJE120 Ergofit are smooth with very slight detail and never piercing or sibilant. They are not bright but very very smooth that can be a great thing for treble sensitive listeners. With an EQ, highs clear up substantially and brings noticeable brightness to the game while remaining free of sibilant or piercing highs.
The sound that leaks out the Ergofit is just a bit below most average earphones, they are not terrible but it is neither their strongest asset. A clearly perceivable sound level will be heard by nearby people which doesn’t make them the best companion for libraries.
The Panasonic RP-HJE120 Ergofit do a pretty good job blocking outside noises. Sound surrounding you will get noticeably reduced without needing to raise the volume to very high levels.
The small size, lightweight plastic housing, featherweight cable and oval eartips combined result in a greatly comfortable earphone that will hold their place and offer pain-free long lasting listening sessions. The flat cone shaped housings ensure a very easy handling of the earpieces to put in and out or reposition at any given moment with little to no effort at all.
Response to Equalization
The response to custom equalization of the Panasonic RP-HJE120 Ergofit is very good generally speaking except for mids and vocals. Highs achieve a much better performance after being custom equalized and no piercing or sibilant highs are introduced. Bass gains much more mid-bass without making the sound signature too muddy. As we said before, mids and vocals do not excel with their response to any custom EQ, not much improvement is made and boxy sounding mids appear.
