| 9 mm Driver |
? The Joyroom JR-E102 have a youthful design, fun color patterns and a very small size. Joyroom’s catalog is not the largest among earphone manufacturers but they have a couple of earphones with interesting designs. The Joyroom JR-E102 are made entirely of plastic with a small form factor and shallow housing, they have a rubbery tangle free flat cable with an inline microphone and a 1-button control that is easy to press. Joyroom sells the JR-E102 in white, blue, pink or green color each one with the cable matching the color of the housing.
on the front of the box it is clearly stated that the Joyroom JR-E102 has a balanced armature, but on the back part of the box… it is written that it holds a 9mm dynamic driver
There is a very confusing technical specification reported on the packaging, on the front of the box it is clearly stated that the Joyroom JR-E102 has a balanced armature, but on the back part of the box where technical details are reported it is written that it holds a 9mm dynamic driver and there is no reference made to any balanced armature. As the housings are not transparent nor translucent there is no way to verify if there is a balanced armature or a 9mm dynamic driver, the size of the housing could fit either but the retail price suggests that probably holds a 9mm driver.

Accessories & Packaging
The box is nicely designed, colored to match the earphone option that you chose. Inside the box is very simple and comes with 3 extra eartips (we got 6 extra eartips but it might probably be a duplicate error made by Joyroom while packing our sample)
Bass & Sub Bass
The Joyroom JR-E102 sub-bass is very rolled off without depth or impact. Mid-bass is recessed, conservative and lacks punch. If you hate strong bass, the JR-E102 might make you happy. When eqed the Joyroom gains depth but every other frequency gets highly recessed. We put the Joyroom JR-E102 to our standardized basshead test and it was able to take 37% of a Fiio E12 amplifier’s maximum power (set to high gain and bass boost turned on); bass got noticeably enhanced considering the unamped performance. They do not deliver any rumble or basshead impact, expect a performance way below the Remax RM-565i and similar impact to the UiiSii Hi-705.

Mids & Vocals
Lower mids are recessed, distant and lack warmth. Middle mids sound tinny and higher mids are harsh. A custom eq can be applied to workaround the problems of the JR-E102; recession can be marginally improved and harshness slightly reduced but not by much.
Highs & Treble
Highs on the Joyroom are forward and piercing but lack detail and definition. They do suffer from sibilance too. Cutting down frequencies on the +/-6kHz eliminates piercing highs and sibilance.
Sound leaking from the Joyroom JR-E102 is high with a performance below many earphones. A mediumly attenuated sound level will be heard by people nearby.
The small form factor of the housing does not make a very good job blocking outside noises, the Joyroom needs medium to high volumes to effectively isolate from environmental sound.
The JR-E102 are very light and small with a tight enough fit as to remain in place but not too tight to become uncomfortable. They are very comfortable to use and having a flush fit they can be used while resting your head sideways on a pillow without generating too much pressure on the ears. According to Joyroom the JR-E102 can be also wore on a sport style passing the cable above and around the ears, we tried this fit with them and they were comfortable and hold their place a little bit stronger.
Response to Equalization
The Joyroom JR-E102 do not respond very well to custom equalization; highs are able to reduce their piercing peaks and sibilance but they are unable to gain any definition or detail, mids and vocals can attenuate slightly their harshness and recover a bit more presence but overall results are not a great improvement, bass gains some depth but at the cost of recessing every other audio frequency.
